The CAT25040 is an EEPROM serial 4-Kb SPI device internally organized as 512x8 bits. ON Semiconductor's advanced CMOS technology significantly reduces device power requirements. It has a 16-byte write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through chip select (CS). Also, the must-have bus signals are the clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input can be used to suspend any serial communication with the CAT25040 device. The device features hardware and software write protection, including partial protection and full array protection.
