DESCRIPTION

This specification covers a range of 16 Kbit I²C bus

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-
