DESCRIPTION
The ST24LC21B, ST24LW21, ST24FC21,
ST24FC21B and ST24FW21 are 1K bit electrically
erasable programmable memory (EEPROM), or-
ganized 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 con-
nection: "C" means WC on pin 7 and "W" means
WC on pin 3.
