6.4. Micron Serial Flash

A Micron Phase Change Memory (PCM) serial flash is provided for user non-volatile storage. PCM memory has greater

write endurance than standard serial flash. This part, NP5Q128A13ESFC0E, is 128 megabit and is accessed by the

SPI Bus.

6.5. MicroSD Memory Card Slot

A MicroSD memory card slot is provided for file system data storage. This is configured to use SPI mode rather than

nibble mode.
