GXSC FRAM Replaces MB85RS128FM25V01 in Valve Control Applications

Modern valve control has evolved from traditional manual operation to intelligent automation, requiring real-time storage of critical information such as valve opening parameters, operational status, fault logs, and calibration data. At the same time, it must withstand harsh industrial environments characterized by extreme temperatures, strong electromagnetic interference, and frequent start-stop cycles, placing high demands on the reliability, write endurance, data retention capability, and low-power consumption of storage devices.

Leveraging advanced ferroelectric storage technology, GXSC FRAM offers a pin-to-pin replacement for the MB85RS128/FM25V01, fully meeting the storage requirements of smart valve control. It is currently widely used in control modules for various types of electric valves, solenoid valves, and control valves. Compared to other types of memory, such as flash memory or EEPROM, ferroelectric memory offers superior reliability in data retention.

The core technology of GXSC FRAM combines ferroelectric and silicon-gate CMOS processes to form non-volatile memory cells. It integrates the high-speed read/write capabilities of SRAM with the non-volatile advantages of EEPROM, enabling data retention during power outages without the need for a backup battery. Its 128K storage capacity meets the parameter and data storage requirements of smart valve control systems.

Valve control systems may face sudden power outages or unstable power supplies. Critical information such as valve position parameters, fault logs, and calibration data must be retained long-term after a power failure to prevent the loss of system parameters and control abnormalities upon restart. The GXSC FRAM supports up to 1 million erase/write cycles and can retain data for 10 years at 85°C (200 years at 25°C), ensuring stable data storage even under these harsh conditions.

Smart valve control modules have limited space, with compact internal PCB layouts, and some portable or battery-powered valve controllers have high power consumption requirements. The GXSC FRAM uses a compact 8-pin SOP package, making it small enough to be flexibly embedded into the compact PCB layout of valve control modules, thereby saving board space.
