24FC512T-E/OT

The 24FC512T-E/OT is a 512-kbit serial I2C EEPROM with extended temperature rating. Key points:
- Non-volatile memory: 64 kB of storage, retained without power.
- Interface: I2C two-wire, with 16-bit memory addressing for accessing the full range.
- Features: supports random and sequential reads and page writes; designed for low-power operation.
- Package: small 8-pin device suitable for embedded systems.
- OT suffix: extended operating temperature, intended for industrial/automotive environments.
- Common uses: storing configuration data, calibration tables, logs, or other firmware data that must persist across power cycles.
In short, it’s a large-capacity, I2C EEPROM optimized for reliable, non-volatile storage in harsh or temperature-critical applications.

Equivalent 512 Kbit I2C serial EEPROMs:
- AT24C512 (Atmel → Microchip)
- CAT24C512 (ON Semiconductor)
- M24C512-W (STMicroelectronics)
Note: check exact temperature range, package, and addressing (512Kb uses 2-byte addressing) for your automotive/extended-temp requirements.
