Description
The Microchip Technology Inc. 24AA01/24LC01B (24XX01*) is a 1 Kbit Electrically Erasable PROM. The device is organized as one block of 128 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 24XX01 also has a page-write capability for up to 8 bytes of data. The 24XX01 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.
