What is eMMC?

Characterized as a storage solution for a wide range of embedded systems, eMMC Storage finds its usage in consumer electronics, handheld computers, smart home appliances, tablets, smartphones, GPS systems, eReaders, IoT, automotive embedded applications and other industrial uses. Embedded MultiMediaCard (eMMC) is an embedded non-volatile NAND flash memory system consisting of the MMC (multimedia card) interface, flash memory and a flash memory controller, which simplifies the application interface design and frees the host processor from low-level flash memory management.

Why is eMMC used in the automotive industry?

eMMC Storage is offered in small BGA (Ball Grid Array) packages which need to be soldered to the board and consume low power in the absence of a constant power source, making it a viable, low-cost memory solution for space-constrained automotive industry applications. The benefits of the non-volatile memory interface design and qualification process of the eMMC aid automotive electronics resulting in a reduction in time-to-market and facilitating support for future eMMC applications. The trend of incorporating Artificial Intelligence in the automotive industry necessitates lower latency rates, optimized performance and adequate storage of web-based data guaranteed by the eMMC. Advanced driver-assistance system (ADAS) prevalent in autonomous automobiles expands their footprint by utilizing the eMMC due to their high-density flash performance. ADAS is the facilitator of adaptive cruise control, automatic lane centering and collision avoidance technologies. The light distance and ranging (LiDAR) system is a prominent ADAS technology that utilizes eMMC for real-time image recognition and helps the vehicle navigate the surrounding environment. Global Automotive Electronics Market demand is anticipated to be valued at $300,332.43m in 2022, forecast to grow at a CAGR of 7.30% to be valued at $607,574.4m from 2022 to 2032. Cars are becoming much more than just modes of transportation with the automotive industry increasingly employing eMMCs due to their smaller footprint, low-power consumption and cost-effectiveness in various cutting-edge applications and workloads such as:

Remarkable Features of FLEXXON’s eMMC beneficial for the automotive industry:

Accelerated processing power, decreased power consumption and increased data storage capacity are crucial to enable connectivity for the automotive industry. FLEXXON’s eMMC has emerged as the optimum data storage technology for the automotive industry. For the automotive applications — including infotainment and ADAS systems — the AEC-qualified eMMC of FLEXXON operates over the ambient temperature range of (-40°C~105°C) in extreme environmental conditions offering reliable, long-term performance, non-volatile data retention, and is JEDEC compatible supporting features such as boot operation, replay protected memory block (RPMB), device health report, field firmware updates, power-off notification, enhanced features for faster and more reliable operation, write leveling, high-priority interrupt (HPI), secure trim/erase, and high-speed. The FLEXXON’s low-power consuming eMMC provides increased efficiency for advanced audio and high-resolution video in embedded automotive applications and delivers fast clock speeds of data with high transfer rates. High-speed performance is achievable through accessing multiple dies inside the FLEXXON’s eMMC, which endorses JEDEC eMMC 5.1 standards with the fastest interface speed (HS400). The automotive-grade embedded eMMC of FLEXXON performs advanced error correction, automatically refreshes the device and is integrated with the SMART feature, i.e., Self-Monitoring Analysis and Reporting Technology, permitting users to monitor the status of their device’s performance, reliability, health monitoring and control. The Linux commands of eMMC aid it in reading the SMART information from the device and examining the quality of health and the remaining life of the eMMC to avoid grave failures. The Global Embedded MultiMediaCard (EMMC) Market Growth Report has nominated FLEXXON as one of the eminent eMMC manufacturers with our eMMC being bootable; it allows automotive applications to have internal flash storage and guarantees interoperability between devices, exhibiting the following features:
  • Tailor-made firmware: The firmware warrants the use of eMMC according to the nature of the automotive application.
  • Highly Integrated eMMC Solution: Exceptional storage capacity of 4GB to 512GB supports an extensive temperature range of -40°C~105°C for automotive applications.
  • Packaged Design: Compact-sized storage device to meet various automotive industries’ high reliability and high-performance needs.
  • Pre-loaded data integrity in the reflow process: Data integrity refers to the reliability and accuracy of automotive data.
