The microcontroller C8051C320 (U1) from SiLabs includes an on-chip USB interface. The firmware is stored in its
internal flash memory (16kB).
The whole power supply is taken from the USB bus by the microcontroller, and converts it internally to 3.3V. No
external LDO is required. The AS5013 is directly powered (VDD and VDDp) by this 3.3V supply.
Connector J4 is used if an external MCU has to be connected to the AS5013 of the demoboard, instead of the
C8051F320. In that case, cut the PCB tracks (bottom side) to disconnect the N40P112 module from the MCU:
Connector J1 is not used and connector J2 is used for ISP programming of the microcontroller only.
All the switches (dome switch: Button EP, Button I, Button II, Button III) are connected directly to the microcontroller.
The unique I²C serial bus (SCL, SDA) controlled by the C8051 microcontroller is used for the N40P112 (AS5013).
The interrupt output INTn is connected directly to the MCU interrupt input.
