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.
