CAT25M02/D
CAT25M02
2 Mb SPI Serial CMOS
EEPROM
Description
The CAT25M02 is a 2M−bit Serial CMOS EEPROM device
internally organized as 256Kx8 bits. This features a 256−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 CAT25M02 device. The device
features software and hardware write protection, including partial as
well as full array protection.
On−Chip ECC (Error Correction Code) makes the device suitable
for high reliability applications.
