DESCRIPTION

The ST24/25E16 are 16 Kbit electrically erasable

programmable memories (EEPROM), organized

as 8 blocks of 256 x8 bits. It is manufactured in

STMicroelectronics’s Hi-Endurance Advanced

CMOS technology which guarantees an endur-

ance of one million erase/write cycles over the full

supply voltage range, and a data retention of over

40 years. The ST25E16 operates with a power

supply value as low as 2.5V.
