32 Kbit I2C EEPROM for configuration storage
The Microchip 24LC32AFT-I/SN is a 32 Kbit serial EEPROM with an I2C interface, organized as 4K x 8 bits. The part is packaged in an 8-pin SOIC (0.154" width, 3.90 mm body) for surface-mount assembly.
Read and write timing for the bus
The write cycle time is 5 ms per page or byte, so a full 32 Kbit write (512 bytes) takes roughly 2.5 seconds if done sequentially. For designs that log data at sub-second intervals, consider whether the 5 ms write delay fits the update rate; if not, a dual-bank or larger page-size EEPROM may be needed.
The part is ROHS3 compliant.
