CAT25256
256-Kb SPI Serial CMOS
EEPROM
Description
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 CAT25256 device. The device features
software and hardware write protection, including partial as well as
full array protection.
for high reliability applications.*
