• Includes advanced analog features such as a 1 Msps 10-bit ADC, dual comparators, and on-chip temperature measurement.
• Supports human-machine interface applications through CTMU-based mTouch capacitive sensing and external graphics interfaces.
• Features flexible peripheral pin select (PPS) allowing remapping of digital functions to simplify PCB layout.

Microcontrollers Applications

• Industrial control systems requiring robust communication interfaces
• Audio and multimedia devices utilizing I2S and USB connectivity
• Human-machine interface (HMI) panels with capacitive touch controls
• General-purpose embedded applications in consumer electronics

Microcontrollers Procurement Notes

Verify the specific suffix 'I/RG' against official Microchip documentation to confirm the exact package type and temperature rating. Ensure compatibility with existing board layouts by cross-referencing the 64-pin pinout diagrams. Confirm that the required memory size and peripheral count align with the project specifications before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a balance of processing power and peripheral density is needed in a compact form factor. The 64-pin package offers sufficient I/O for moderate complexity designs. Consider the 100 MHz clock speed and available memory for applications requiring real-time processing. Evaluate the integrated CTMU if touch sensing is a requirement to reduce external component count.

Microcontrollers Part Context

This device belongs to the PIC32MX3xx series, which are high-performance 32-bit flash microcontrollers designed for general-purpose and USB applications. The series shares architectural similarities with the PIC32MX4xx family but differs in specific peripheral availability and memory configurations. It is part of Microchip's broader portfolio of MIPS-based MCUs aimed at cost-sensitive and space-constrained designs.

Microcontrollers Replacement Considerations

Direct substitutes within the same family include the PIC32MX330F064L (100-pin TQFP/VTLA) and PIC32MX350F128H (64-pin QFN/TQFP). Verify pin compatibility and memory differences when considering these alternatives. Cross-family migration to PIC32MX4xx devices requires checking for USB OTG feature availability and pin mapping changes.
