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). 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.

For Ordering Information details, see page 17.
