DESCRIPTION
This specification covers a range of 4K bits I 2 C bus
EEPROM products, the ST24/25C04, the
ST24C04R and the ST24/25W04. In the text, prod-
ucts are referred to as ST24/25x04, where "x" is:
"C" for Standard version and "W" for hardware
Write Control version.
The ST24/25x04 are 4K bit electrically erasable
programmable memories (EEPROM), organized
as 2 blocks of 256 x 8 bits. They are manufactured
in SGS-THOMSON’s Hi-Endurance Advanced
CMOS technology which guarantees an endur-
ance of one million erase/write cycles with a data
retention of 40 years. The memories operate with
a power supply value as low as 1.8V for the
ST24C04R only.
Both Plastic Dual-in-Line and Plastic Small Outline
packages are available.
