CAV25040 Overview

SPI Serial CMOS EEPROM

CAV25010, CAV25020,
CAV25040
1-Kb, 2-Kb and 4-Kb SPI
Serial CMOS EEPROM
Description
The CAV25010/20/40 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
CAV25010/20/40 device. These devices feature software and
hardware write protection, including partial as well as full array
protection.
