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.
