DESCRIPTION

The CAT25C32/64 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 CAT25C32/

64 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

required to access the device. The

HOLD

pin may be

used to suspend any serial communication without

resetting the serial sequence. The CAT25C32/64 is

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.
