Microchip 24LC32AT 32Kbit I²C Serial EEPROM 4K x 8 SOT-23-5

Microchip 24LC32AT 32Kbit I²C Serial EEPROM is a 32 kilobit (4K x 8-bit) I²C serial Electrically Erasable Programmable Read-Only Memory in a compact SOT-23-5 surface-mount package. Its low-voltage design supports reliable operation down to 1.7V while consuming minimal power, with standby and active currents of 1µA and 1mA respectively.

Overview

Engineered with Schmitt trigger inputs for improved noise immunity and output slope control to eliminate ground bounce, this EEPROM supports clock frequencies of 100kHz and 400kHz. A fast page write capability allows up to 32 bytes of data to be written with a maximum write time of 5ms, and a self-timed write cycle simplifies programming.

Key Features

• High reliability: low-power CMOS technology, over 1 million erase/write cycles and data retention exceeding 200 years
• Enhanced system design: up to eight devices on the same I²C bus, for a combined address space of up to 256Kbit
• Robust protection: hardware write-protect pin and ESD protection rated greater than 4000V
• Wide operating range: single supply voltage from 2.5V to 5.5V and temperature range of -40°C to +85°C

Applications

Suited to power-sensitive, portable applications as well as demanding industrial and automotive environments, this serial EEPROM is used for storing configuration data, calibration settings, and other critical information in electronic systems.
