Description
The Microchip Technology Inc.
24AA02E48/24AA025E48/24AA02E64/24AA025E64
(24AA02XEXX) 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 interface.
Low-voltage design permits operation down to 1.7V,
with maximum standby currents of only 1 µA for
I-Temp. and 5 µA for E-Temp., as well as a maximum
active current of 1 mA. The 24AA02XEXX also has a
page write capability for up to eight bytes of data
(16 bytes on the 24AA025E48/24AA025E64). The
24AA02XEXX is available in the standard 8-pin
SOIC, 5-lead SOT-23, and 6-lead SOT-23 packages.
