GXSC FRAM Replaces MB85RS2M/FM25V20 in Industrial Controllers

Industrial controllers are used in industrial automation systems to receive sensor signals, execute control algorithms, and output control commands, thereby enabling automated management and precise control of industrial production processes. During continuous industrial production, controllers frequently need to update process parameters, equipment operating status, fault logs, and calibration data. This places high demands on storage chips in terms of real-time write capability, high-frequency endurance, data reliability upon power failure, and wide-temperature stability.

Traditional memory technologies such as Flash or EEPROM suffer from high write latency, limited erase/write endurance, and an inability to support real-time high-frequency rewriting. Prolonged high-frequency operation can easily lead to data loss, making it difficult to meet the high-frequency and high-reliability data storage requirements of modern industrial equipment. With its ultra-high read/write endurance and latency-free real-time writing, GXSC FRAM serves as an ideal replacement for traditional Flash and EEPROM storage solutions in industrial controllers, while also offering excellent adaptability to industrial environments.

GXSC FRAM employs ferroelectric process technology and silicon-gate CMOS process technology to form non-volatile memory cells. Unlike SRAM, the chip does not require a battery to retain data. The memory cells used in this chip support up to 1E11 read/write operations, offering read/write endurance that far exceeds that of FLASH and EEPROM. Furthermore, it does not require the long data write times or wait states associated with FLASH or EEPROM.

The performance specifications of GXSC FRAM are as follows:

• Capacity: 2 Mbit, with SPI interface;

• Operating frequency: 25 MHz;

• High-speed read feature: Supports 40 MHz high-speed read command;

• Operating temperature range: -40°C to 85°C;

• Package types: SOP8 150mil package, SOP8 208mil package, RoHS compliant;

• Performance-compatible with MB85RS2MT (Fujitsu) and FM25V20A (Cypress).
