2.3 SPI EEPROM Memory
A 1M-bit +3.3V SPI serial EEPROM Memory, Atmel AT45DB011-SC, is provided on
the 56F827EVM, reference
. This memory connects directly to the SPI Port
through a header on the 56F827. It can be used to load program code and data into the
56F827’s internal or external memory spaces. A jumper block is provided, JG7, to allow
the user to disconnect the on-board SPI EEPROM from the SPI port and allow him to
connect his own SPI port peripheral. The header details are shown in
.
