EEPROM Memory IC 32Kb (4K x 8) I²C 400 kHz 900 ns 8-TSSOP The 24AA32A-I/ST is a 32 Kbit (4 K × 8) Serial EEPROM developed by Microchip Technology. It uses the I²C (Inter-Integrated Circuit) interface, allowing simple communication with microcontrollers and other digital systems.

This device is designed for non-volatile data storage, meaning it retains stored data even when power is removed. It is commonly used in applications such as configuration storage, calibration data, device identification, and logging.

The “I” variant indicates industrial temperature range, while “ST” refers to the TSSOP package.

Key Features Memory 32 Kbit EEPROM (4096 × 8 bytes) Page write capability (up to 32 bytes per write cycle) Organized for efficient sequential and random access Interface I²C serial interface (2-wire: SDA, SCL) Supports standard speeds: 100 kHz (Standard mode) 400 kHz (Fast mode) Hardware address pins allow multiple devices on the same bus Power Characteristics Wide operating voltage: 1.7V to 5.5V (low-voltage operation) Low power consumption: Standby current in microamp range Optimized for battery-powered systems Reliability & Endurance Write endurance: up to 1 million erase/write cycles Data retention: typically >200 years Built-in write protection features Functional Features Self-timed write cycle (no external timing needed) Byte write and page write modes Sequential read capability Schmitt trigger inputs for noise immunity 🌡️ Physical & Environmental Package: 8-lead TSSOP (ST) Operating temperature: –40°C to +85°C (industrial grade)#commonpartslibrary #integratedcircuit #memory
