DESCRIPTION
The CAT24AC128 is a 128kbit Serial CMOS EEPROM
internally organized as 16,384 words of 8 bits each.
Catalyst鈥檚 advanced CMOS technology substantially
reduces device power requirements. The CAT24AC128
features a 64-byte page write buffer. The device operates
via the I
2
C bus serial interface and is available in 8-pin
DIP, 8-pin SOIC or 14-pin TSSOP packages. Three
device address inputs allows up to 8 devices to share a
common 2-wire I
2
C bus.
