CAT25010, CAT25020,

CAT25040

1-Kb, 2-Kb and 4-Kb SPI

Serial CMOS EEPROM

Description

The CAT25010/20/40 are 1−Kb/2−Kb/4−Kb Serial CMOS

EEPROM devices internally organized as 128x8/256x8/512x8 bits.

They feature a 16−byte page write buffer and support the Serial

Peripheral Interface (SPI) protocol. The device is enabled through a

Chip Select (CS) input. In addition, the required bus signals are a clock

input (SCK), data input (SI) and data output (SO) lines. The HOLD

input may be used to pause any serial communication with the

CAT25010/20/40 device. These devices feature software and

hardware write protection, including partial as well as full array

protection.
