AT21CS01-STUM10-T

Based on a 1Kb single-wire I²C EEPROM core, the AT21CS01-STUM10-T from Microchip Technology stores important data reliably over long periods.

Specifications include 1Kb (128 bytes) of memory, single-wire I²C interface, 1.7V ~ 3.6V supply range, and the SOT-23-3 footprint. Clock frequencies up to 125 kHz are supported. Its single-wire I²C implementation saves pins on dense boards while keeping the familiar I²C protocol, useful for identification and small data storage in wearables and modules.
