DESCRIPTION
The
CAT25010/20/40
are
1-Kb/2-Kb/4-Kb
Serial
CMOS EEPROM devices internally organized as
128x8/256x8/512x8 bits. They feature a 16-byte page
write buffer and support the Serial Peripheral Interface
(SPI) protocol. The device is enabled through a Chip
Select (CS
) input. In addition, the required bus signals
are a clock input (SCK), data input (SI) and data
output (SO) lines. The HOLD
input may be used to
pause
any
serial
communication
with
the
CAT25010/20/40
device.
These
devices
feature
software and hardware write protection, including
partial as well as full array protection.
