DESCRIPTION
The CAT24C01B is a 1K-bit Serial CMOS EEPROM
internally organized as 128 words of 8 bits each. Catalyst鈥檚
advanced CMOS technology substantially reduces de-
vice power requirements. The CAT24C01B features a
4-byte page write buffer. The device operates via a 2-
wire serial interface and is available in 8-pin DIP, 8-pin
SOIC, 8-pin TSSOP or 8-pin MSOP.
