3.4 PIC32CM SG00/GC00 Microcontroller

The PIC32CM SG00/GC00 Curiosity Pro development board is based on the PIC32CM5112SG00100 or PIC32CM5112GC00100 device, which is a 72 MHz Arm® Cortex®-M23 processor with up to 512 KB Flash/w ECC, 32 KB SRAM, a 12-bit ADC module, an enhanced Peripheral Touch Controller and External Bus Interface (which can be used in some graphics applications), two CAN-FD modules, six Serial Communication interfaces (SERCOM) and one Full-Speed USB. The package assembled in the board is a 100-pin TQFP of 0.5 mm pitch.

The PIC32CM5112SG00100 device also features Trustzone and a full-secure enclave (HSM) for providing a high level of security.

The following figures illustrate the PIO schematic and power schematic.

Important:

The following component values must be optimized to see expected performance as is specified in the Electrical Characteristics chapter of the MCU data sheet:

  • FB304: Change by a ferrite bead of at least 500 mA with a maximum value of DC Resistance of 0.1Ω and an impedance ≥600Ω at 100 MHz
  • C325: Change by a ceramic capacitor with a minimum value of 33 uF with ESR<0.5Ω
  • C328: Change by a ceramic capacitor with a minimum value of 33 uF with ESR<0.5Ω
  • C332: Change by a ceramic capacitor with a minimum value of 10 uF, X7R with ESR<0.5Ω
