2.3.2
Included on CRD5378 is an 8051-type microcontroller with integrated hardware SPI and USB interfaces.
This C8051F320 microcontroller is a product of Silicon Laboratories (http://www.silabs.com). Key features
of the C8051F320 microcontroller are:
The exact use of the microcontroller features is controlled by embedded firmware.
C8051F320 has dedicated pins for power and the USB connection, plus 25 general purpose I/O pins that
connect to the various internal resources through a programmable crossbar. Hardware connections on
CRD5378 limit how the blocks can operate, so the port mapping of microcontroller resources is detailed
below.
