CAV25256

256-Kb SPI Serial CMOS

EEPROM

Description

The CAV25256 is a 256−Kb Serial CMOS EEPROM device

internally organized as 32Kx8 bits. This features a 64−byte page write

buffer and supports the Serial Peripheral Interface (SPI) protocol. The

device is enabled through a Chip Select (CS) input. In addition, the

required bus signals are clock input (SCK), data input (SI) and data

output (SO) lines. The HOLD input may be used to pause any serial

communication with the CAV25256 device. The device features

software and hardware write protection, including partial as well as

full array protection.
