EEPROM 4k SPI interface

The CAT25320 is a 32-Kb Serial CMOS EEPROM device internally organized as 4096x8 bits. This features a 32−byte 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 CAT25320 device. The device features software and hardware write protection, including partial as well as full arrayp rotection.
