Description
Operating at a supply voltage range of 2.0V to 3.6V, the FM25V20A-G supports standard SPI (Serial Peripheral Interface) communication, which facilitates easy integration into microcontroller-based systems. It has a wide temperature range, typically from -40°C to +85°C, suitable for industrial environments. The FM25V20A-G's non-volatility ensures data retention even when power is lost, making it ideal for applications in data logging, industrial control, and automotive systems where data integrity is critical. Its compact design and robust performance make it a versatile choice for embedded systems requiring persistent memory storage.
Equivalent

Pinout
Pin Count and Functions:
- Pin Count: The FM25V20A-G typically comes in an 8-pin Small Outline Integrated Circuit (SOIC) package.
Pin Functions:
1. CS (Chip Select): Activates the device when low, allowing access to data.
2. SCK (Serial Clock): Synchronizes the data transfer between the FRAM and the microcontroller.
3. SI (Serial Input): Takes in data from the microcontroller to the FRAM.
4. SO (Serial Output): Sends data from the FRAM to the microcontroller.
5. WP (Write Protect): Disables writing to the status register when low, ensuring data integrity.
6. HOLD: Pauses the serial communication without deselecting the device.
7. VSS (Ground): Ground reference for the device.
8. VDD (Power Supply): Provides the necessary power to the device.
These pins facilitate the FRAM’s operation, allowing for high-speed, non-volatile memory access with unlimited endurance.
