49.1 Introduction
This chapter describes a common checklist which must be used when starting and reviewing the schematics for a PIC32CM JH00/JH01 design. This chapter illustrates the recommended power supply connections, how to connect external analog references, programmer, debugger, oscillator and crystal.
This information is not intended to be exhaustive. Its objective is to cover as many configurations of use as possible.
Refer to the Basic 32-Bit MCU Design and Troubleshooting Checklist guide on the Microchip web site.
If the device is operating in an environment with much electromagnetic noise it must be protected from this noise to ensure reliable operation. In addition to following best practice EMC design guidelines, the recommendations listed in the schematic checklist sections must be followed. In particular, placing decoupling capacitors very close to the power pins, an RC-filter on the RESET pin, and a pull-up resistor on the SWCLK pin is critical for reliable operations. It is also relevant to eliminate or attenuate noise in order to avoid that it reaches supply pins, I/O pins, and crystals.
