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 (C¯¯S) input. In addition, the required bus signals

are a clock input (SCK), data input (SI) and data

output (SO) lines. The H¯¯O¯L¯D¯ 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.
