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

The MICROCHIP 24LC32AT-I/OT is a 32 kilobit (4K x 8-bit) I²C serial Electrically Erasable Programmable Read-Only Memory (EEPROM) in a compact SOT-23-5 surface-mount package. Its advanced, low-voltage design allows for reliable operation down to just 1.7V, consuming minimal power with standby and active currents of only 1µA and 1mA respectively. This makes it an ideal solution for power-sensitive, portable applications.

Engineered with robust features, this EEPROM includes Schmitt trigger inputs for superior noise immunity and output slope control to eliminate ground bounce, ensuring data integrity in electrically noisy environments. It supports clock frequencies of 100kHz and 400kHz, offering flexibility for various system speeds. The device boasts a fast page write capability for up to 32 bytes of data with a maximum write time of 5ms, along with a self-timed write cycle for simplified programming.
