CAT25080, CAT25160
8-Kb and 16-Kb SPI Serial
CMOS EEPROM
Description
devices internally organized as 1024x8/2048x8 bits. They feature a
32−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 CAT25080/25160
device. These devices feature software and hardware write protection,
including partial as well as full array protection.
