Microchip 24AA32 32K 1.8V Serial EEPROM Datasheet
The 24AA32 is a 4K × 8 (32 Kbit) serial EEPROM from Microchip Technology, designed for low‑power applications with a wide operating voltage range of 1.8 V to 6.0 V. It supports up to eight devices on a single I²C‑compatible two‑wire bus, providing up to 256 Kbits total memory.
Key features include high‑endurance memory blocks (10 M write cycles), low standby current, ESD protection over 4000 V, and fast write performance using an internal 64‑byte cache. The device is offered in 8‑pin PDIP and SOIC packages and operates from 0 °C to +70 °C (commercial) or –40 °C to +85 °C (industrial).
