The central design challenge in touch-driven industrial equipment is maintaining reliable sensing in environments where noise, moisture, and electromagnetic interference are routine conditions. The PIC32CM5112GC00 addresses this through a dedicated peripheral touch controller (PTC) that supports up to 324 mutual-capacitance channels or 36 self-capacitance channels, with Driven Shield+ technology to improve noise immunity and maintain performance on wet surfaces. Wake-on-touch from standby sleep mode allows the sensing subsystem to remain active while the processor core is powered down, which keeps average current low in applications where the panel must remain responsive at all times without draining the supply.
The functional safety architecture is built to ISO 26262:2018, with error correction code (ECC) and fault injection capability on both the 512KB Flash and 128KB SRAM. The memory built-in self-test (MBIST) is accessible in user mode, and there is a fail-safe clock monitor with automatic safe-clock switching, and write protection of peripheral registers through the peripheral access controller. Together these features allow safety requirements to be addressed at the hardware level rather than relying on software workarounds, reducing the certification burden for the wider system.
Communications flexibility is provided by dual CAN-FD modules compliant with ISO 11898-1:2015, a full-speed USB 2.0 interface with on-chip transceiver, and six SERCOM interfaces each configurable as USART, I2C, SPI, RS-485, IrDA, or LIN host/client. This combination allows the MCU to connect simultaneously to a vehicle or industrial network, a local host processor, and lower-level sensors without external bridge components.
The analog front-end includes a 12-bit ADC running at up to 4.5Msample/s across up to 12 channels, supported by two analog comparators with programmable voltage references. SleepWalking allows peripherals including the ADC and event system to continue operating while the core sleeps, enabling autonomous data acquisition without software polling and reducing the frequency of processor wake events.

The PIC32CM GC00 Curiosity Pro is a Microchip Technology development board featuring a 72MHz Arm® Cortex®-M23 microcontroller, requiring no additional hardware to get started.
The development board is designed to make it easy to prototype and evaluate applications based on the PIC32CM SG00/GC00 microcontroller family. The board comes ready to use out of the box, with an integrated MPLAB PICkit On-Board 4 debugger handling programming and real-time debugging over a single USB connection. Expansion options are plentiful, with Arduino UNO R3, mikroBUS, and Xplained Pro extension headers all present, making it straightforward to connect shields, click boards, and Microchip expansion boards. A solid set of onboard peripherals includes dual CAN transceivers, a precision voltage reference, touch and tactile buttons, user LEDs, and a potentiometer. This variety means there is plenty to work with before reaching for any expansion hardware at all.
