CAT25128
128-Kb SPI Serial CMOS
EEPROM
Description
The CAT25128 is a 128Kb Serial CMOS EEPROM device
internally organized as 16Kx8 bits. This features a 64byte 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 CAT25128 device. The device features
software and hardware write protection, including partial as well as
full array protection.
OnChip ECC (Error Correction Code) makes the device suitable
for high reliability applications.*
