Description

The Microchip Technology Inc. 24AA02/24LC02B (24XX02*) is a 2 Kbit Electrically Erasable PROM. The device is organized as one block of 256 x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.8V, with standby and active currents of only 1 µA and 1 mA, respectively. The 24XX02 also has a page write capability for up to 8 bytes of data. The 24XX02 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP and MSOP packages and is also available in the 5-lead SOT-23 package.
