Description:
The Microchip Technology Inc. 24C01SC and
24C02SC are 1K-bit and 2K-bit Electrically Erasable
PROMs with bondpad positions optimized for smart
card applications. The devices are organized as a
single block of 128 x 8-bit or 256 x 8-bit memory with a
two-wire serial interface. The 24C01SC and 24C02SC
also have page-write capability for up to 8 bytes of data.
