24AA32A-I/ST

24AA32A-I/ST Description

The 24AA32A-I/ST from Microchip Technology is a 32Kbit (4K x 8) I2C-compatible serial EEPROM, designed for high-performance, low-power applications. Operating within a 1.8V to 5.5V supply range, it supports a 400 kHz clock frequency and features a fast 900 ns access time, making it suitable for systems requiring rapid data retrieval. The device is organized as 4,096 bytes of 8-bit memory, with byte-level and page-level write capabilities (up to 32 bytes per page). Its 5ms write cycle time ensures efficient data storage, while its I2C interface simplifies integration into microcontroller-based designs. Packaged in an 8-pin TSSOP, it is ideal for space-constrained applications.
