PIC32CM1216MC00032-E/RTB 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash for code, SRAM for data), and programmable peripherals on one die. The PIC32CM MC00 family uses the ARM Cortex-M0+ core — a 32-bit, von-Neumann architecture optimized for low power and deterministic interrupt response, making it the smallest and most energy-efficient member of the Cortex-M family. The 'PIC32CM' prefix places this device within Microchip's 5V-tolerant MCU portfolio aimed at industrial and automotive motor control.
Key features include a 12-channel DMA controller, 12-channel Event System, 16-channel ADC, 10-channel Analog Comparator (AC), 2-channel DAC, 6 SERCOM modules (configurable as UART/SPI/I2C), 4 TC and 3 TCC waveform output timers, a Configurable Custom Logic (CCL) block, and a Peripheral Event Controller (PDEC) for quadrature decoding. It also integrates a temperature sensor and operates across the -40C to +125C extended temperature range.
The Cortex-M0+ core uses the Thumb-2 instruction subset, providing 0.93 DMIPS/MHz while keeping the silicon area small. The PDEC hardware block offloads quadrature encoder counting from the CPU, enabling precise motor-speed loops without software overhead — critical for BLDC and PMSM motor control. SERCOM reconfiguration lets one peripheral serve as UART, SPI, or I2C, reducing BOM cost and giving board designers pin-out flexibility.
Typical applications include BLDC/PMSM motor drives, sensorless fan controllers, small appliance pumps, HVAC damper actuators, and LIN-node automotive body modules. The 5V-tolerant I/O directly interfaces with industrial 24V systems via external transceivers, eliminating level shifters.
When designing with this device, dedicate PCB ground copper under the exposed thermal pad and route motor-phase signals away from the crystal to avoid EMI coupling. Use the MPLAB X IDE with the MPLAB Harmony v3 framework for peripheral configuration and motor-control code generation.

主な用途
PIC32CM1216MC00032-E/RTB の用途: 6 件s: BLDC Motor Control (Sensorless FOC), LIN-Node Automotive Body Modules, HVAC Damper and Valve Actuators, Small Appliance Pumps and Fans, Industrial Sensor Hubs, Portable Consumer Devices.
BLDC Motor Control (Sensorless FOC)
The PIC32CM1216MC00032-E/RTB is purpose-built for sensorless Field-Oriented Control of BLDC and PMSM motors. Its integrated PDEC hardware block decodes quadrature encoder inputs offloading the CPU, while the three TCC waveform outputs generate complementary 3-phase PWM with programmable dead-time insertion. The 10-channel analog comparator array detects BEMF zero-crossings for sensorless commutation at speeds up to 50,000 RPM. With 48MHz Cortex-M0+ compute, the MCU executes the full FOC loop (Clarke/Park transforms, PI current control) in under 20 microseconds, leaving headroom for UART diagnostics and CAN/LIN stack. The wide 2.7V-5.5V supply directly drives 24V industrial bus rails via onboard pre-regulators.
おすすめ
LIN-Node Automotive Body Modules
The PIC32CM1216MC00032's SERCOM modules support UART framing compatible with LIN 2.1 slave stacks, making the device ideal for automotive body controllers such as seat adjusters, mirror modules, and window lifters. The MCU's extended -40C to +125C operating range meets AEC-Q100 Grade 1 thermal endurance requirements for under-hood and cabin deployments. Six configurable SERCOM instances allow simultaneous LIN communication plus SPI sensor interfacing and I2C EEPROM backup. The 128KB Flash stores the LIN node configuration and diagnostic UDS services, while 16KB SRAM holds the message buffer and transport layer state. Microchip's Harmony LIN stack is pre-certified to LIN conformance test specifications.
おすすめ
HVAC Damper and Valve Actuators
In HVAC damper and valve actuator designs, the PIC32CM1216MC00032-E/RTB combines 16 ADC channels for temperature/pressure sensing with 3 TCC outputs for servo motor PWM. The Configurable Custom Logic (CCL) block implements hardware safety interlocks — for example, disabling actuator drive on overcurrent without CPU intervention, satisfying IEC 60730 Class B functional safety requirements. The 12-channel Event System routes ADC end-of-conversion events directly to DMA, enabling zero-CPU-overhead sensor sampling at 100kS/s. With its small 5x5mm VQFN footprint, the MCU fits inside compact actuator housings alongside the motor and H-bridge.
おすすめ
Small Appliance Pumps and Fans
The PIC32CM1216MC00032-E/RTB powers cost-optimized sensorless pumps and fans in white goods. Its 5V-native I/O eliminates level-shifters required by 3.3V-only MCUs, reducing BOM cost. The integrated temperature sensor enables overtemperature protection by monitoring the die junction temperature during high-current motor stalls. The PDEC and TCC blocks together implement single-shunt sensorless FOC for pump drives, while SERCOM channels communicate with a master controller over UART or LIN. The 128KB Flash accommodates closed-loop control algorithms, fault logging, and OTA bootloader support for field firmware updates.
おすすめ
Industrial Sensor Hubs
In industrial sensor hubs aggregating temperature, pressure, and flow measurements, the PIC32CM1216MC00032's 16 ADC channels and 6 SERCOM interfaces connect to multiple analog and digital sensors simultaneously. The 12-channel DMA offloads continuous data acquisition, while the Event System triggers conversions on timer or external interrupts without CPU wakeup. The 5V-tolerant I/O directly interfaces with industrial 4-20mA loop sensors and 24V digital inputs via simple resistive dividers. The MCU's 48MHz core processes MODBUS RTU framing and checksum calculations in real time, while the 16KB SRAM buffers measurement frames before transmission.
おすすめ
Portable Consumer Devices
Although optimized for industrial 5V environments, the PIC32CM1216MC00032-E/RTB also serves battery-powered consumer products requiring high computational throughput at low cost. Its Cortex-M0+ core delivers 0.93 DMIPS/MHz at active currents below 4mA, and its peripheral SleepWalking modes enable sensor polling while the CPU remains idle. The 5x5mm VQFN package fits inside wearable form factors, while the 128KB Flash stores graphics libraries, BLE stack fragments, and USB device class firmware. Microchip's MPLAB Harmony v3 includes turnkey application examples for sensor fusion, audio playback, and capacitive touch UI.

設計ノート
Estimated: At maximum CPU activity (48MHz, all peripherals enabled), the VQFN-32 package dissipates approximately 30mW (3.3V × 9mA active current). With theta_JA of 40 C/W on a 4-layer JEDEC EIA/JESD51 1oz test board, junction temperature rise is only 1.2 C above ambient — thermal management is generally not a concern for this MCU even at +125 C ambient, provided the exposed thermal pad is soldered to a continuous ground copper pour of at least 25mm².
Place a single 100nF X7R decoupling capacitor within 2mm of each VDD pin, plus a bulk 4.7uF X5R capacitor on the main VDD rail. The exposed thermal pad (EP) must be soldered to a continuous ground plane with at least 9 thermal vias (0.3mm drill, 0.5mm pitch) to the inner ground layer. Keep crystal traces within 5mm of the XIN/XOUT pins and guard them with a ground ring to avoid EMI pickup that can corrupt USB or LIN timing.
Do not enable SERCOM pad remapping while a peripheral is active — always disable the peripheral before changing PMUX settings. When using the PDEC for quadrature decoding, ensure the QDI inputs are mapped to adjacent pins to minimize input skew (data sheet specifies 10ns max). Failing to clear the TC and TCC interrupt flags before enabling interrupts causes spurious first-interrupt events that hang motor-control loops.
