DESCRIPTION

The CAT25256 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

¯¯¯¯¯ input may be used to pause any serial

HOLD

communication with the CAT25256 device. The

device features software and hardware write protec–

tion, including partial as well as full array protection.
