GXSC Replaces MB85RS2M/FM25V20 in Test Signal Conditioning Systems

Test signal conditioning systems serve as data hubs for industrial measurement and control as well as precision instruments. During system operation, they continuously generate massive amounts of raw sample data and real-time operating parameters. Data storage for these systems must meet certain requirements for real-time performance, reliability, and durability. Guoxin Sicheng’s SF25C20 ferroelectric memory employs advanced ferroelectric storage technology, combining the high-speed random read/write capabilities of RAM with the non-volatile storage characteristics of ROM, making it ideally suited for signal conditioning systems.

High-speed signal sampling systems have high data update frequencies and require storage devices with no write latency or erase wait times, capable of responding in real time to high-frequency data write requests. The SF25C20’s read/write speed can reach 1E11 read/ operations—far exceeding the endurance of traditional EEPROMs. Frequent use of EEPROMs can lead to wear and the risk of data loss, whereas the SF25C20’s high durability ensures stable data storage and retrieval in test signal conditioning systems, guaranteeing long-term, stable system operation.

The advantages of using the SF25C20 in test signal conditioning systems are as follows:

• Low power consumption: 4.5 mA, with standby power consumption of only 1 µA, making it suitable for low-power devices such as Industrial Internet of Things (IIoT) terminals (e.g., test signal conditioning systems)

• High-speed response: Read/write speed reaches 1E11 read/write operations, with read/write endurance far exceeding that of FLASH and EEPROM.

• Long lifespan: Data retention capability of 10 years at 85°C (200 years at 25°C); stored data will not be lost even under harsh environmental conditions over extended periods.

• High operating frequency: All devices operate at 25 MHz and support 40 MHz high-speed read commands, meeting the demands of applications requiring high data read/write speeds.

• Compact packaging: Available in SOP8 150-mil and SOP8 208-mil packages, these devices are small in size, easy to install and solder, and help save PCB space.
