DESCRIPTION
The CAT24AC128 is a 128kbit Serial CMOS EEPROM internally organized as 16,384 words of 8 bits each. Catalyst’s advanced CMOS technology substantially reduces device power requirements. The CAT24AC128 features a 64-byte page write buffer. The device operates via the I2C 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 I2C bus.
