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 per-

mits 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.
