Overview

The PIC32CM6408PL10028-E/3LW is a 32-bit Arm Cortex-M0+ microcontroller designed for 5V operation in harsh environments, supporting temperatures up to 125C. It integrates 64KB of Flash and 8KB of RAM with robust analog peripherals including a 12-bit ADC and a Peripheral Touch Controller (PTC).

Why Choose This Part

This MCU offers a rare combination of modern 32-bit processing with a wide 1.8V to 5.5V supply range, eliminating the need for 3.3V regulators in many designs. Its SleepWalking technology allows peripherals to trigger interrupts and process data while the CPU remains in standby, significantly reducing power consumption to approximately 2uA.

Applications

Industrial Sensor Nodes
Leverages the 5V supply capability and 125C temperature rating for reliable operation in electrically noisy and hot industrial environments.
Capacitive Touch Interfaces
Utilizes the integrated Peripheral Touch Controller (PTC) to implement buttons, sliders, and wheels with high noise immunity.
Household Appliances
The 5V I/O support simplifies interfacing with standard power electronics and relays without level shifters.
Safety-Critical Monitoring
Features such as the Programming and Debugging Interface Disable (PDID) and Error Correction Code (ECC) options enhance system integrity.
