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
* Catalyst Semiconductor is licensed by Philips Corporation to carry the I2C Bus Protocol.
I Commercial, industrial and extended
automotive temperature ranges
I Write protect feature
– Entire array protected when WP at V
