YEESTOR eMMC Enhances Storage Performance for In-Vehicle Infotainment (IVI) Systems.

Operating systems, applications, and multimedia data. Compared to traditional UFS or SD card solutions, eMMC has become the mainstream choice due to its high integration, standardized interface, and balanced performance. Its built-in flash memory controller automatically handles bad block management and wear leveling, allowing developers to quickly implement storage functions without delving into NAND characteristics, effectively lowering the R&D barrier. eMMC's Execute-in-Place (XIP) capability supports fast system boot, while its compact packaging fits the limited space within vehicle interiors.

In smart cockpit infotainment (IVI) systems, a 128GB eMMC plays the key role of system data storage and multimedia caching. This capacity can fully accommodate the vehicle operating system, Amap navigation data, offline media libraries, and user personalization settings, providing ample storage space for multi-screen interaction. Its core value is reflected in three aspects: firstly, high-speed read performance, supporting the HS400 mode of the eMMC 5.1 protocol with sequential read speeds up to 350MB/s, ensuring smooth loading of large navigation applications and 4K videos; secondly, excellent random read/write capability, with 4KB random read/write performance exceeding 8,000 IOPS, meeting multi-tasking concurrency demands; thirdly, power consumption control, with standby power below 1mW and operating power consumption about 30% lower than traditional solutions, helping to optimize overall vehicle energy efficiency management. For example, in dual-system parallel scenarios, eMMC can simultaneously support data exchange between the instrument cluster and the central control screen, improving system response efficiency by over 40%.

YEESTOR's SGM8103K is a 128GB industrial-grade eMMC chip, utilizing pMLC flash memory particles and a BGA-153 package (11.5×13.0×1.0mm). The device complies with the eMMC 5.1 standard, supports HS400 high-speed mode, achieves an interface frequency of 200MHz, and delivers a peak read speed of 350MB/s. Its key parameters demonstrate significant advantages: the pMLC architecture provides 3,000 program/erase cycles, which is three times that of ordinary TLC solutions; the industrial-grade temperature range of -40°C to 85°C is suitable for automotive environments; and the built-in LDPC error correction algorithm ensures data integrity. Compared with similar products, its performance is highlighted in:

1. Storage Architecture: pMLC particles ensure write endurance throughout the vehicle system's 10-year lifecycle.

2. Temperature Adaptability: Full-temperature data retention from -40°C to 85°C, superior to the consumer-grade standard of 0°C to 70°C.

3. Read/Write Stability: Read/write performance fluctuation across the full temperature range is <5%, avoiding lag risks under extreme temperatures.

4. Packaging Process: 1.0mm ultra-thin profile, aiding the slim design of central control modules.

The chip integrates an intelligent temperature regulation mechanism, maintaining stable read/write operations even in -40°C low-temperature environments and automatically triggering speed-limiting protection at 85°C high temperatures. Its hardware encryption engine supports AES-256 data encryption, meeting the secure boot requirements of vehicle systems. In IVI system applications, the SGM8103K can directly connect to mainstream automotive-grade SoCs (such as Qualcomm 8155, Renesas R-Car H3), enhancing the fluidity of multi-application switching through 4KB random read/write optimization. As an official authorized partner of YEESTOR, MANDU provides comprehensive support including chip selection guidance, signal integrity simulation, free sample applications, and mass production assurance, helping customers obtain automotive-grade certification.

For smart cockpit R&D engineers, the YEESTOR SGM8103K eMMC, with its industrial-grade reliability, long-life architecture, and automotive-grade adaptability, is an ideal choice for central control storage systems. Its pMLC technology can effectively handle frequent system log writes, and its hardware encryption features ensure user data security.
