Description:
The Microchip Technology Inc. 24AA02E48/
24AA025E48 (24AAXXXE48*) is a 2 Kbit Electrically
Erasable PROM. The device is organized as two
blocks of 128 x 8-bit memory with a 2-wire serial inter-
face. Low-voltage design permits operation down to
1.7V, with maximum standby and active currents of
only 1 ? A and 1 mA, respectively. The 24AAXXXE48
also has a page write capability for up to 8 bytes of
data (16 bytes on the 24AA025E48). The
24AAXXXE48 is available in the standard 8-pin
SOIC, 5-lead SOT-23, and 6-lead SOT-23 packages.
