AT25080 from ATMEL is a serial EEPROM with SPI interface. The device has 8192 bits (1024 bytes) of EEPROM that can be controlled using a 4 wire SPI bus. This example project demonstrates how to interface a PSoC to this device and read and write an array of data using the SPIM user module.
The project and documentation can be downloaded from the below link from Cypress website
