DESCRIPTION
The Microchip Technology Inc. 24C01B and 24C02B
are 1K bit and 2K bit Electrically Erasable PROMs. The
devices are organized as a single block of 128 x 8 bit or
256 x 8 bit memory with a 2-wire serial interface. The
24C01B and 24C02B also have page-write capability
for up to 8 bytes of data. The 24C01B and 24C02B are
available in the standard 8-pin DIP and an 8-pin surface
mount SOIC package.
These devices are for extended temperature
applications only. It is recommended that all other
applications use Microchip鈥檚 24LC01B/02B.
