Description:
The Microchip Technology Inc. 24AA02E48 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 and active currents of
only 1 μA and 1 mA, respectively. The 24AA02E48 also
has a page write capability for up to 8 bytes of data. The
24AA02E48 is available in the standard 8-pin SOIC
and 5-lead SOT-23 packages.
