EEPROM products, the ST24/25C16 and the
ST24/25W16. In the text, products are referred to
as ST24/25x16 where "x" is: "C" for Standard ver-
sion and "W" for hardware Write Control version.
The ST24/25x16 are 16 Kbit electrically erasable
programmable memories (EEPROM), organized
as 8 blocks of 256 x8 bits. These are manufactured
in STMicroelectronics’s Hi-Endurance Advanced
CMOS technology which guarantees an endur-
