DESCRIPTION

The ST24LC21B, ST24LW21, ST24FC21 and

ST24FW21 are 1K bit electrically erasable pro-

grammable memory (EEPROM), organized in

128x8 bits. In the text, products are referred as

ST24xy21, where "x" is either "L" for VESA 1 or "F"

for VESA 2 compatible memories and where "y"

indicates the Write Control pin connection: "C"

means WC on pin 7 and "W" means WC on pin 3.
