DESCRIPTION
The Microchip Technology Inc. 24LC08B/16B are 8K
and 16K bit Electrically Erasable PROMs in ISO mod-
ules for smart card applications. The device is orga-
nized as four or eight blocks of 256 x 8-bit memory with
a 2-wire serial interface. The 24LC08B and 24LC16B
also have a page-write capability for up to 16 bytes of
data.
