FM25256-DN-T-G is a 256Kbit (32KB) SPI interface serial EEPROM chip produced by Fudan Microelectronics, packaged in an 8-pin dual in-line package (DIP-8). It supports a working voltage range of 1.8V to 5.5V, with a maximum clock frequency of up to 20MHz (at 4.5V to 5.5V) or 5MHz (at 1.8V). The chip features a 64-byte page write mode and byte write operations, and supports both hardware and software write protection functions to safeguard partial or entire memory areas. Additionally, it provides a 128-bit unique ID, a 64-byte security area, and an automatic timed write cycle with a maximum duration of 5ms. The FM25256-DN-T-G operates within a temperature range of -40°C to +85°C, with an endurance of up to 1 million write/erase cycles and a data retention period of up to 40 years, making it suitable for a variety of low-power and high-reliability industrial and commercial applications.

Fudan Microelectronics is a leading domestic integrated circuit design company, with significant product and technological advantages in the automotive electronics field. Its EEPROM products, with their high reliability, low power consumption, automotive-grade certification (AEC-Q100), and wide temperature range (-40°C to +125°C), are widely used in Battery Management Systems (BMS), intelligent cockpits, and vehicle systems. The company’s first automotive-grade MCU, the FM33LG0xxA series, features an Arm Cortex-M0 core, offering high reliability, low power consumption, high security, and a rich set of peripheral interfaces, suitable for applications such as body electronics, trunk control, and headlight control. In addition, Fudan Microelectronics’ security chips support various encryption algorithms to ensure data security. By collaborating with multiple partners, Fudan Microelectronics has established a complete automotive electronics ecosystem, meeting the domestic automotive industry’s demand for domestic chips and promoting the intelligence and domestication of automotive electronics.
