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.
