GXSC Ferroelectric Memory GX85RS128 Replaces MB85RS128FM25V01 in Wireless Modules

Wireless modules are specialized data transmission devices built on DSP and radio technologies. They enable data transfer through control terminals, devices, and cloud platforms, operating across a broad frequency range. These modules primarily handle critical tasks including data transmission/reception, protocol parsing, and temporary storage. In wireless data transmission scenarios, modules frequently store configuration parameters, communication logs, and cache transmitted/received data. Therefore, this article recommends replacing the MB85RS128/FM25V01 with the domestically produced ferroelectric memory GX85RS128 for wireless modules. This constitutes an optimal storage solution for achieving miniaturization and high-performance upgrades in wireless modules.

The GX85RS128 employs ferroelectric technology and silicon-gate CMOS process technology to form non-volatile memory cells. When facing various harsh outdoor environmental conditions such as high temperatures, low temperatures, vibration, and electromagnetic interference, the GX85RS128 offers excellent anti-interference capabilities and a wide operating temperature range, enabling stable data storage under these challenging conditions. Compared to traditional storage types like flash memory or EEPROM, ferroelectric memory offers superior reliability in data preservation, ensuring secure storage of device-related information.

Wireless module configuration parameters (e.g., frequency band, baud rate, address code, encryption key) require long-term stable retention without loss even during power outages. The FM25V01 achieves 10 years of data retention at 85°C (200 years at 25°C) without battery power, far exceeding the typical lifespan of wireless modules. It also offers industrial-grade temperature adaptability (-40°C to +85°C), ensuring stable data preservation in extreme environments and preventing configuration loss due to temperature fluctuations or power outages.

The GX85RS128 operates within a voltage range of 2.7V to 3.6V, with a minimum standby power consumption of just 9 microamperes. It reliably stores data without delay under low-current conditions, preventing data loss after power failure. Key specifications:

• Capacity: 128Kb

• Interface Type: SPI interface (Mode 0 and Mode 3)

• Operating Voltage: 2.7V to 3.6V
