FM24C16B-G

FM24C16B-G is a 16-Kbit I2C serial EEPROM from the FM family. It provides non-volatile, byte-addressable storage for embedded systems (2048 bytes, 2K × 8). Accessed over the I2C two-wire bus (SDA, SCL) with a standard 7‑bit device address (set by A0–A2 pins or fixed by package variant). It supports page writes (typically 16 bytes per write) with a write cycle around ~5 ms. Endurance is about 1,000,000 write cycles and data retention spans decades. The G suffix usually indicates RoHS-compliant packaging; exact temperature range varies by grade (often -40 to 85 °C or -40 to 125 °C). Features include a WP (write protect) pin for protection and low-power standby. Common uses: small configuration data, calibration constants, logs, and other non-volatile storage for microcontrollers. For precise pinout, voltage range, timing, and addressing details, consult the official FM24C16B-G datasheet.

Equivalent 16-kbit I2C serial EEPROMs from major vendors include:
- ST M24C16-W
- Microchip 24LC16B / 24AA16
- Rohm BR24C16
- Giantec GT24C16
They use the same 2-wire I2C interface, 16 Kbit capacity, and 8-pin packages. Verify exact pinout and A0–A2 address pins for cross‑fit.

FM24C16B-G is a 16‑Kbit I2C EEPROM. Common applications include:
- Storing non-volatile MCU configuration and calibration data
- Device identity info (serial numbers, lot/date codes) for traceability
- Small data logging and parameter history
- External configuration storage for consumer, automotive, and industrial electronics
- Firmware/parameter backup for embedded systems needing persistent memory
These use cases leverage its simple I2C interface, small footprint, and low power.

FM24C16B-G is packaged in an 8-pin SOP (SO-8) package, RoHS-compliant (green).
