CAT25080/D
CAT25080, CAT25160
EEPROM Serial 8/16-Kb SPI
Description
The CAT25080/25160 are a EEPROM Serial 8/16−Kb SPI devices
internally organized as 1024x8/2048x8 bits. They feature a 32−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 CAT25080/25160 device. These
devices feature software and hardware write protection, including
partial as well as full array protection.
