Fudan Microelectronics' Self-Developed Memory Chip Passes AEC-Q100 Automotive Grade Verification
Recently, the self-developed memory chips of Shanghai Fudan Microelectronics Group Co., Ltd. have passed AEC-Q100 Grade 1 automotive-grade verification by the authoritative third-party testing and certification organization — the East China Branch of the Fifth Electronics Research Institute of the Ministry of Industry and Information Technology · Integrated Circuit Reliability Verification Public Service Platform — and have begun to be deployed in vehicles.
Introduction to the products of Fudan Micro that passed automotive-grade verification this time
The automotive-grade FM24C512DA1 provides 524,288-bit serial electrically erasable programmable read-only memory (EEPROM), internally organized as 65,536 bytes of 8 bits each, and supports a 128-bit UID and a 128-byte security sector. Through cascading, up to 8 FM24C512DA1 devices can share a single I2C bus. This product is suitable for automotive-grade applications such as T-BOX, smart cockpit, domain controller, dashcam, ADAS advanced driver assistance, BMS battery management system, infotainment system, powertrain, safety and chassis.
Fudan Microelectronics' existing industrial-grade serial EEPROM memory series covers capacities from 1 Kbit to 2 Mbit and offers three interfaces: Microwire, I2C and SPI. In addition to the 512K I2C interface EEPROM automotive product launched this time, the Fifth Electronics Research Institute will fully support Fudan Microelectronics in launching a full series of automotive-grade products compliant with AEC-Q100 Grade 1.
– I2C interface EEPROM roadmap: 16K/32K/64K/128K/256K/512K (AEC-Q100 certificate obtained)/1M/2Mbit
– SPI interface EEPROM roadmap: 32K/64K/128K/256K/512K/1M/2M/4Mbit
– Automotive-grade products (64K–4Mbit) developed on the new process platform will fully embed ECC online error correction logic, significantly improving product reliability. Key AC, DC and reliability indicators of the new EEPROM series will fully benchmark against industry-leading products, with some indicators leading the industry.
Fudan Microelectronics' existing industrial-grade serial SPI NOR Flash memory covers capacities from 1 Mbit to 512 Mbit. The Fifth Electronics Research Institute will fully support Fudan Microelectronics in launching a full series of automotive-grade products compliant with AEC-Q100 Grade 2. Currently, the 64M NOR Flash is under certification.
Fudan Microelectronics' existing industrial-grade serial/parallel NAND Flash memory covers capacities from 1 Gbit to 8 Gbit and offers two interfaces: PPI and SPI. The Fifth Electronics Research Institute will fully support Fudan Microelectronics in launching a full series of automotive-grade products compliant with AEC-Q100 Grade 2. Currently, the SPI interface 1G NAND Flash is under certification.
– SPI interface NAND Flash products: 1G/2G/4G/8Gbit
– PPI interface NAND Flash products: 2G/4G/8Gbit
Shanghai Fudan Microelectronics Group Co., Ltd. ("Fudan Microelectronics", SSE STAR Market stock code: 688385.SH; "Shanghai Fudan", HKEX stock code: 01385.HK) is a professional company in China engaged in the design, development, production (testing) of very large scale integrated circuits and the provision of system solutions. Founded in July 1998, the company was listed in Hong Kong in 2000, transferred to the Hong Kong Main Board in 2014, and is the earliest-established and first-listed joint-stock integrated circuit design enterprise in China. In 2021, it listed on the SSE STAR Market, forming an "A+H" capital structure.
Fudan Microelectronics Group currently has five major product lines. As a globally leading supplier, its non-volatile memory business has formed three major product lines: EEPROM, SPI NOR Flash, SPI NAND Flash and specialty memory, making it one of the companies with the most complete non-volatile memory product lines in China. Among them, its EEPROM industrial market share ranks first in China, and multiple projects in the automotive electronics field have entered mass production.
The Security and Identification Division's smart IC card and RFID/READER chips have cumulative shipments exceeding 10 billion units, among which the security chip FM1280 and NFC reader chip have passed AEC-Q100 assessment. Cumulative shipments of low-power and industrial MCUs rank first in China, and the FM33LG0XXA series has completed AEC-Q100 verification. With a market share of over 50% in smart appliances, it is the most advantageous supplier in China, and its products are widely used in new energy electric vehicle charging piles.
Fudan Microelectronics Group is the first domestic manufacturer to launch 100-million-gate FPGA products (programmable chips), and also owns the first PSoC introduced to the domestic market. This product can meet the application requirements of high-speed communication, signal processing, image processing, industrial control and other fields, and has received positive market feedback.
Currently, Fudan Microelectronics Group is actively developing a new generation of billion-gate products based on 14/16nm process technology, maintaining its leading position in domestic FPGA technology.
