DESCRIPTION

The CAT25C33/65 is a 32K/64K-Bit SPI Serial CMOS

EEPROM internally organized as 4Kx8/8Kx8 bits.

Catalyst’s advanced CMOS Technology substantially

reduces device power requirements. The CAT25C33/

65 features a 64-byte page write buffer. The device

operates via the SPI bus serial interface and is enabled

though a Chip Select (CS). In addition to the Chip Select,

the clock input (SCK), data in (SI) and data out (SO) are

designed with software and hardware write protection

features including Block write protection. The device is

available in 8-pin DIP, 8-pin SOIC, 14-pin TSSOP and

20-pin TSSOP packages.
