DESCRIPTION

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

serialsequence.TheCAT25C01/02/04/08/16isdesigned

with software and hardware write protection features

including Block Write protection. The device is available

in 8-pin DIP, 8-pin SOIC, 8-pin MSOP and 8/14-pin

TSSOP packages.

The CAT25C01/02/04/08/16 is a 1K/2K/4K/8K/16K Bit

SPI Serial CMOS EEPROM internally organized as

128x8/256x8/512x8/1024x8/2048x8 bits. Catalyst’s

advanced CMOS Technology substantially reduces

device power requirements. The CAT25C01/02/04

features a 16-byte page write buffer. The 25C08/16

featuresa32-bytepagewritebuffer.Thedeviceoperates

via the SPI bus serial interface and is enabled though a
