Additional Details:

The FM25VN02-G operates on a single power supply, typically between 2.7V and 3.6V. It comes in a standard 8-pin SOIC package for easy surface mounting. The SPI interface comprises four signals: Serial Clock (SCK), Master In Slave Out (MISO), Master Out Slave In (MOSI), and Chip Select (/CS). The device is compatible with both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). Its page write capability allows writing up to 256 bytes of data in a single operation, enhancing write efficiency. A hardware write protect pin (/WP) is available for safeguarding data against unintended modifications. Deep Power-down mode is designed to minimize power consumption when the device is idle. The FM25VN02-G is suitable for applications demanding dependable non-volatile storage for settings, calibration data, or user-specific information. Its robust construction and wide operating temperature make it ideal for various industrial applications.
