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.","metaTitle":"Microchip 24LC32AFT-I/SN 32Kbit I2C EEPROM, 400 kHz, 8-SOIC","metaDescription":"Microchip 24LC32AFT-I/SN 32Kbit I2C EEPROM, 400 kHz clock, 900 ns access, -40 to 85°C, 8-SOIC.
