DESCRIPTION
The Microchip Technology Inc. 24LC04B/08B is a 4K or
8K bit Electrically Erasable PROM. The device is orga-
nized as two or four blocks of 256 x 8-bit memory with
a 2-wire serial interface. Low voltage design permits
operation down to 2.5 volts with typical standby and
active currents of only 5
µ
A and 1 mA respectively. The
24LC04B/08B also has a page-write capability for up to
16 bytes of data. The 24LC04B/08B is available in the
standard 8-pin DIP and both 8-lead and 14-lead surface
mount SOIC packages.
