Jichuang Northern ICNL9951R: Enabling "2.5K High Brush + Active Pen"

In today's world, where tablets and smart control screens are ubiquitous, how can we achieve smoother touch control, a more delicate display, and a more accurate pen-writing experience at a more cost-effective price?

Today, I want to recommend a truly powerful TDDI (Touch Display Driver Integration) CPU to those of you who are deeply involved in this field—the ICNL9951R from Chipone Technology.

This is more than just a chip; it's a "performance monster" tailor-made for the mainstream 8-11 inch market! How does it single-handedly solve the three biggest headaches: interference, space constraints, and power consumption? Read on to find out! 👇

Key highlights at a glance: More than just TDDI, it's a cutting-edge "cascading" technology.
The ICNL9951R is an in-cell touch display driver chip designed specifically for A-Si, IGZO, and LTPS panels. Its biggest selling point lies in its flexible single- or dual-chip cascading architecture!

Single-chip mode: Supports 800RGB x 2560 resolution, focusing on high cost-performance small-sized tablets.

Dual-chip cascade mode: This is its "big move"! By cascading two IC NL9951R, it easily supports 2.5K ultra-high-definition resolution of 1600RGB x 2560 (WQXGA).

What does this mean? It means that you don't need an expensive high-end single chip; with two cost-effective ICNL9951R chips, you can give your product a flagship-level Retina display experience!

Application scenarios: This is a perfect match for these three types of products!
Based on the ICNL9951R's perfect coverage of 8-11 inch screens and its support for active pens, the following three scenarios are its absolute domain:

Scenario 1: Education & Productivity Tablets
Nowadays, it's almost embarrassing to release an online learning or light office device without a pen. The ICNL9951R natively supports active pen functionality, and with its high 120Hz display refresh rate, it delivers a smooth and highly responsive writing experience, whether students are taking notes or professionals are annotating PDFs.

Scenario 2: Smart Home Control Panels
High-end smart homes are evolving towards 8-inch and 10-inch screens. The ICNL9951R's In-cell technology allows for a thinner and more aesthetically pleasing central control screen. Meanwhile, its powerful anti-interference capabilities (discussed in detail below) ensure accurate and error-free touch control even in complex home electromagnetic environments.

Scenario 3: Rear Seat Entertainment Screen
Automotive electronics require extremely high stability. The ICNL9951R supports multiple panel materials such as A-Si and IGZO, offering strong adaptability. Its CABC (Content Adaptive Brightness Control) function effectively reduces screen power consumption and heat generation, a significant advantage for electronic devices in the enclosed space of a vehicle.

🛠️ Solving pain points: The engineer's "aspirin," a cure for all kinds of discomfort.
During the research and development process, engineers often face the dilemma of "wanting more, wanting more, and wanting more." Let's see how the ICNL9951R resolves these challenges:

Pain Point 1: What to do about severe signal interference causing the touch screen to "jump around"?
👉 ICNL9951R Solution: Time Division Multiplexing + Intelligent Frequency Hopping

In an in-cell screen, display signals and touch signals are like two people living in the same room, easily "fighting".

The ICNL9951R employs time division multiplexing (TDM) technology, which staggers the display driving and touch scanning in time so that they do not interfere with each other.

Even more impressive is its built-in Intelligent Frequency-Hopping algorithm! When there is strong noise interference in the environment, the chip will automatically "change lanes" and switch to a clean frequency band for touch scanning. Combined with a high signal-to-noise ratio (SNR) analog front-end (AFE), even if you have a high-power device next to you, the touch function will remain as stable as ever!

Pain Point 2: Onboard space is extremely limited, and wiring is too difficult. What can be done?
👉 ICNL9951R Solution: RAM-less Architecture + TDDI Integration

Traditional solutions may require external RAM or separate touch IC and display IC, which takes up a lot of PCB space.

The ICNL9951R adopts a RAM-less design, which directly reduces the chip size. As an SoC (System on Chip), it integrates the display driver, timing control (T-CON), and touch control into a single chip.

In addition, it supports MIPI C-PHY. Compared with the traditional D-PHY, C-PHY can transmit higher data volume with fewer wire pairs (3 wires transmit 2.28 bits/symbol), which greatly reduces the number of FPC traces and makes your board layout cleaner!

Pain Point 3: What to do about the severe overheating and drastic battery life caused by high refresh rate screens?
👉 ICNL9951R Solution: CABC + Low Power Mode

While high refresh rates are enjoyable, they consume a lot of power. The ICNL9951R incorporates CABC (Content Adaptive Brightness Control) functionality. Instead of simply adjusting the backlight, it intelligently reduces backlight brightness and adjusts pixel transmittance based on the currently displayed image content (e.g., if the image itself is already bright), significantly reducing backlight power consumption while maintaining image quality.

Meanwhile, it supports five low-power operation modes, including deep standby and gesture wake-up, ensuring that every milliampere of power is used effectively.

⚔️ 3. Competitor Comparison: A Single Sentence Reveals the Secret
Compared to conventional TDDI products of the same specifications on the market, the biggest advantage of ICNL9951R is:

"Utilizing a unique two-chip cascade architecture, it achieves a perfect coexistence of 2.5K ultra-high resolution and 120Hz high refresh rate without increasing process costs, and boasts a touch sampling rate of up to 240Hz, doubling performance while being more cost-effective!"

(Many competing products can only make low-resolution screens, or they require expensive single-chip solutions to make high-resolution screens, and it is difficult to support an active stylus and high refresh rate at the same time.)

📝 4. More key parameters (for technical experts' reference)
Resolution support: up to 800 RGB for single chip, up to 1600 RGB for dual-chip cascade.

Interface: Supports MIPI DSI-2 (D-PHY V1.1 / C-PHY V1.1). C-PHY speeds up to 1100Msps/trio.

Touch channels: Supports up to 800 touch nodes (16x50), providing an extremely high-precision, fully-fitted in-cell experience.

Image quality enhancement: Built-in algorithms such as CE (color enhancement), DGC (digital gamma correction), and sunlight screen visibility enhancement, so you don't need to worry about calibration; the image quality is already excellent.

Packaging: Supports COG and COF, adaptable to different module designs.

A good chip is not only about its specifications, but also about the service!

We provide full-process technical support, from schematic design and layout suggestions to driver debugging. Whether you're aiming to create a blockbuster tablet or a high-end industrial control screen, the ICNL9951R is an indispensable choice.

🔰 𝐂𝐡𝐢𝐩𝐖𝐨𝐫𝐥𝐝 𝟖𝐆𝐛 𝐒𝐏𝐈 𝐍𝐀𝐍𝐃: 𝐗𝐓𝟐𝟔𝐆𝟏𝟖𝐃

Dear engineers and purchasing partners, in today's increasingly complex embedded systems, memory capacity and throughput are often performance bottlenecks. ChipWorld's XT26G18D is a 3.3V SPI NAND Flash that combines 8Gb (1024MB) of high capacity with a high frequency of 120MHz. It not only solves the problem of numerous pins in traditional parallel NAND, but also provides exceptional transmission performance while maintaining SLC stability.

𝐃𝐞𝐞𝐩𝐥𝐲 𝐚𝐝𝐚𝐩𝐭𝐞𝐝 𝐭𝐨 𝐭𝐡𝐫𝐞𝐞 𝐦𝐚𝐣𝐨𝐫 𝐚𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐬𝐜𝐞𝐧𝐚𝐫𝐢𝐨𝐬

High-end smart door locks and security vision: Modern smart locks integrate functions such as 3D face recognition and video intercom, with firmware packages often reaching hundreds of MB in size. The XT26G18D provides a large 4352-byte page (4K+256B) that supports fast random access, ensuring high-speed loading of face models and voice libraries, and improving the smoothness of interaction.

In-vehicle infotainment and instrument cluster systems: The automotive environment requires devices to remain reliable even under extreme temperatures. This chip supports industrial-grade operating temperatures, and its SLC technology guarantees 60,000 write/erase cycles, making it ideal for storing in-vehicle Linux/RTOS operating system images and high-precision map data.

5G Industrial Gateway and High-Performance Router: In network communication equipment, the XT26G18D's Quad I/O mode data transmission rate can reach 480Mbit/s. This enables the device to decompress and load large kernel files at extremely fast speeds during power failure and restart, significantly reducing service interruption time.

𝐀𝐝𝐝𝐫𝐞𝐬𝐬𝐢𝐧𝐠 𝐭𝐡𝐞 𝐜𝐨𝐫𝐞 𝐩𝐚𝐢𝐧 𝐩𝐨𝐢𝐧𝐭𝐬 𝐨𝐟 𝐞𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐬

Limited PCB space and layer count: Parallel NAND typically requires over 40 pins, while the XT26G18D uses a WSON8 (8x6mm) package. This compact layout minimizes routing requirements, requiring only a few GPIOs to drive 8Gb capacity, reducing PCB area and helping to reduce the design cost of multi-layer boards.

Waste of computing resources in ECC control: Many low-end controllers lack powerful hardware ECC capabilities, and software error correction would consume a significant number of CPU cycles. This chip integrates an 8-bit hardware ECC engine (per 528 bytes). Error correction is automatically completed when data is read from the Flash array into the cache, allowing the controller to directly read "clean" data, greatly optimizing system efficiency.

Data security and intellectual property protection: The chip has a built-in 128-bit unique ID (UID), which gives each chip a globally unique identity. Combined with a 16K-byte lockable OTP area, engineers can permanently lock the authorization key of the core algorithm to prevent the device from being maliciously copied or the firmware from being illegally cloned.

When original equipment manufacturers (OEMs) allocate more production capacity to high-end/enterprise-grade products and older process resources are converging, the "delivery time and allocation" of NAND flash memory often has a greater impact on production than the unit price.

👉Delivery breakpoint from sample to mass production
👉Procurement Material Confirmation Schedule

🔷𝐂𝐚𝐬𝐞 𝐑𝐞𝐯𝐢𝐞𝐰
Positioning terminal: Samples can be coordinated, mass production becomes "pending production", and the first batch is split into two deliveries. Remedial measures: forecast + frame order to ensure production first, and verify backup materials in parallel.

Industrial control equipment: The AVL suffix was not clearly specified, and the temperature rating of batches of goods arrived inconsistently, triggering retesting and BOM modification. Remedial action: Freeze the complete order code and incoming material verification list.

🔶𝐂𝐨𝐧𝐜𝐥𝐮𝐬𝐢𝐨𝐧𝐬 𝐚𝐧𝐝 𝐀𝐜𝐭𝐢𝐨𝐧 𝐋𝐢𝐬𝐭
Treat NAND as a "rhythm material" management system: write out the complete order code and freeze it; use rolling forecasting + frame single-lock window; prioritize testing/documentation; use "to the factory" as the delivery date metric.

This article briefly discusses the use of NAND in real-world projects and how customers typically make selection decisions.

In actual projects, capacity is not the primary decision-making factor.

1. Which projects will prioritize NAND?
Based on project experience over the past two years, NAND mainly focuses on:

◾️ Positioning terminal/vehicle terminal
◾️ Industrial control equipment
◾️ Communication daughter board
◾️ Instruments and data acquisition equipment

These projects have several things in common:

◾️ Firmware size is relatively controllable
◾️ Limited data write frequency
◾️ High requirements for system stability
◾️ Long product life cycle

II. What points do customers typically focus on during the product selection phase?
1. Startup stability
Many projects are quite sensitive to startup time and system failure rate.

SLC offers relatively controllable read/write consistency, making it more popular in devices with high reliability requirements.

2. Eraser/write life and temperature range
Industrial control and outdoor equipment typically require a wider temperature range and a longer lifespan.

NAND flash memory performs better in terms of write cycles and data retention, making it easier to meet long-term operating requirements.

III. Some Supplements Based on the Current Market Situation
Currently, the overall supply and demand of NAND remains tight, especially for mature models.

If the project plan is relatively clear, it is recommended to pay attention to the subsequent production schedule during the prototype stage.

From the perspective of the agent's experience:

For new projects, don't wait until the final design is completed before confirming materials.
Mature projects can be planned in stages according to the annual plan.

Communicating in advance will make things more relaxed.

IV. XTX NAND Common Model List
Based on the models we currently collaborate with most, please refer to our previous article: ChipWorld NAND Product Introduction for project reference:

In recent years, ChipWorld has accumulated some mass production cases in industrial control and communication projects, which have demonstrated the stability and delivery schedule of its NAND product line.

Specific model parameters, packaging form, and temperature rating can be further matched according to project requirements.

During the NAND selection phase, capacity is only a basic requirement.

More importantly:

◾️ System architecture matching
◾️ Lifecycle planning
◾️ Production scheduling and supply stability

Since the Spring Festival, we have received numerous inquiries from customers regarding NAND pricing and delivery times. Based on recent price inquiries and online news, we have compiled a brief summary of the current market situation for your reference.

𝐈. 𝐒𝐋𝐂 𝐍𝐀𝐍𝐃: 𝐒𝐮𝐩𝐩𝐥𝐲 𝐚𝐧𝐝 𝐝𝐞𝐦𝐚𝐧𝐝 𝐫𝐞𝐦𝐚𝐢𝐧 𝐭𝐢𝐠𝐡𝐭, 𝐰𝐢𝐭𝐡 𝐭𝐡𝐞 𝐩𝐚𝐜𝐞 𝐬𝐥𝐢𝐠𝐡𝐭𝐥𝐲 𝐞𝐚𝐬𝐢𝐧𝐠 𝐜𝐨𝐦𝐩𝐚𝐫𝐞𝐝 𝐭𝐨 𝐛𝐞𝐟𝐨𝐫𝐞 𝐭𝐡𝐞 𝐋𝐮𝐧𝐚𝐫 𝐍𝐞𝐰 𝐘𝐞𝐚𝐫.

Currently, the overall supply of 2Gb/4Gb SLC NAND is still in a relatively tight balance:

Mainstream models maintain high prices
Delivery time is generally longer
The factory is operating at full capacity, prioritizing existing projects.

The main demands are concentrated in:

Industrial control equipment
Positioning terminal
Communication products
Long-term projects that are already in mass production

Based on recent developments:

Not a sustained, rapid rise
It's more like a high-level operation under long-term tight supply and demand.

For existing mass production projects, if the annual usage is relatively clear, it is more prudent to plan for some safety stock in advance; for new projects, it is recommended to get involved in material confirmation as early as possible to avoid being forced to adjust the schedule later.

Starting this week, we're seeing some changes to some commonly used capacities:

Prices for some models are starting to become negotiable.
Inventory pressure has become apparent in distribution channels.
A small number of models can be made available from stock.

The main reason is:

The recovery in consumer goods is slower than expected.
Channels that stocked up heavily before the Lunar New Year are starting to release their inventory.

It should be noted that:

The current situation is one of localized easing, not a full-scale decline.

Overall, the changes are still structural, differentiated by model and channel.

In short:

SLC is tight, TLC is locally relaxed.

𝐈𝐈𝐈. 𝐀 𝐫𝐞𝐜𝐞𝐧𝐭 𝐩𝐫𝐨𝐣𝐞𝐜𝐭'𝐬 𝐚𝐜𝐭𝐮𝐚𝐥 𝐬𝐢𝐭𝐮𝐚𝐭𝐢𝐨𝐧

Last week, a customer who manufactures positioning terminals was evaluating whether to postpone placing an order and wanted to observe the price further.

When it was confirmed this week, the originally coordinated delivery date had been postponed, so it had to be split into two batches for delivery: one batch to be produced first, and the other to be supplied with materials.

Similar situations have become increasingly common recently.

Often, what affects the project's pace is not just the unit price, but also the production scheduling window and material coordination.

𝐈𝐕. 𝐒𝐨𝐦𝐞 𝐒𝐮𝐠𝐠𝐞𝐬𝐭𝐢𝐨𝐧𝐬 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐏𝐫𝐨𝐜𝐮𝐫𝐞𝐦𝐞𝐧𝐭 𝐒𝐢𝐝𝐞

Based on the current market conditions, our usual advice to clients is:

For projects already in mass production, a portion of the usage can be locked in advance based on actual consumption.
New project phase: Complete sampling and selection confirmation first, without waiting for the "ideal price".
If you plan to lower prices and wait for a pullback, the market is currently still in a high-level consolidation range, and there are no clear signs of a significant short-term correction.

From a cyclical perspective, it's closer to:

It's consolidating at a high level, rather than in a rapid downward phase.

𝐈𝐧 𝐜𝐨𝐧𝐜𝐥𝐮𝐬𝐢𝐨𝐧

We have seen many examples of this in periodic devices like NAND flash memory:

Small changes in unit price often have a greater impact on a project than delivery time and stability.

Proper material planning is more important than reactive measures.

If you are pushing forward:

Positioning products
Industrial control equipment
Communication terminal
Projects involving SLC/TLC NAND

Feel free to contact me anytime. I can assist with the selection process, delivery time, and current channel availability to help keep the project's pace within a predictable range.
