DESCRIPTION

The CAT25010/20/40 is a 1K/2K/4K Bit SPI Serial

CMOS EEPROM internally organized as 128x8/256x8/

512x8 bits. Catalyst’s advanced CMOS Technology

substantially reduces device power requirements. The

CAT25010/20/40 features a 16-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 CAT25010/

20/40 is designed 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-pin TSSOP packages.
