DESCRIPTION

The CAT25C128/256 is a 128K/256K-Bit SPI Serial

CMOS EEPROM internally organized as 16Kx8/32Kx8

bits. Catalyst’s advanced CMOS Technology

substantially reduces device power requirements. The

CAT25C128/256 features a 64-byte page write buffer.

The device operates via the SPI bus serial interface

and is enabled through a Chip Select (CS). In addition

to the Chip Select, the clock input (SCK), data in (SI)

and data out (SO) are required to access the device.

The HOLD pin may be used to suspend any serial

communication without resetting the serial sequence.

The CAT25C128/256 is designed with software and

hardware write protection features including Block Lock

protection. The device is available in 8-pin DIP, 8-pin

SOIC, 14-pin TSSOP and 20-pin TSSOP packages.
