PIC24EP32MC202-E/MM Обзор
A 16-bit MCU (microcontroller unit) is a single-chip computer integrating a CPU core, program memory (Flash), data memory (RAM), peripherals, and I/O on one silicon die. Within the broader semiconductor taxonomy it sits below 32-bit MCUs and above 8-bit MCUs in processing capability, while still offering lower power and deterministic interrupt latency than most 32-bit Cortex-M devices. The 16-bit PIC24E architecture uses a modified Harvard design with a 24-bit instruction word and 16-bit data path, enabling DSP-class operations and high-throughput motor-control math in a single cycle.
Key differentiating features of the PIC24EP32MC202-E/MM include up to six 10/12-bit ADC channels, three op-amps, three analog comparators, a Peripheral Trigger Generator (PTG), and dedicated Motor Control PWM (MCPWM) outputs. The integrated op-amps and comparators remove the need for external analog signal conditioning in current-sense and back-EMF sensing topologies. The 60 MIPS performance envelope, combined with the 16-bit DSP engine, lets the device execute field-oriented control (FOC) loops in real time for BLDC and PMSM motors.
Typical target applications are automotive and industrial motor drives, including HVAC blowers, electric water pumps, fuel pumps, BLDC fans, e-bike controllers, and small servo drives. The 28-QFN package is footprint-compatible with the rest of the PIC24EP32MC2xx family, allowing a single PCB to support multiple motor power tiers by swapping only the MCU.
When designing with this part, place the exposed pad (EP) on the QFN package over a continuous copper pour with at least 6 thermal vias to the inner ground plane to meet the -40°C to +125°C extended-grade thermal envelope. Decouple VDD with a 100 nF X7R ceramic capacitor placed within 3 mm of the pin, and follow the datasheet guidance for the analog VDD/VSS pair (AVDD/AVSS) when using the on-chip ADCs and op-amps.
This page synthesizes distributor pricing tiers, drop-in same-package alternatives, and PCB-layout design notes that complement the official Microchip datasheet for the PIC24EP32MC202-E/MM.

Типичное применение
PIC24EP32MC202-E/MM подходит для 6 применениеs: Automotive BLDC Cooling Fan, Electric Water Pump / Oil Pump, Industrial Servo / Small Stepper Drive, E-Bike / Pedelec Motor Controller, Drones / Quadcopter ESC (Electronic Speed Controller), Home Appliance Variable-Frequency Motor (Washer / Compressor).
Automotive BLDC Cooling Fan
The PIC24EP32MC202-E/MM is ideal for 12V/24V automotive HVAC and radiator cooling fans. Its integrated MCPWM module drives a 3-phase inverter bridge directly, while the three on-chip op-amps condition shunt-resistor current feedback for closed-loop torque control. At 60 MIPS, the PIC24E core runs sensorless back-EMF commutation at 25 kHz with margin for PI speed loops. The AEC-Q100 qualification plus extended -40 °C to +125 °C temperature grade meets under-hood thermal demands, and the 28-QFN 6x6 mm footprint keeps PCB area small enough to fit inside the fan hub. Reference design Microchip AN1078 demonstrates sensorless FOC on this device class.

Electric Water Pump / Oil Pump
Automotive electric coolant and oil pumps demand high efficiency and long life; the PIC24EP32MC202-E/MM delivers both. Its 60 MIPS PIC24E core supports field-oriented control (FOC) of the PMSM pump motor, while the three analog comparators handle zero-crossing back-EMF detection for sensorless startup from standstill. The integrated op-amps eliminate external current-sense amplifiers, shrinking the BOM and reducing leakage paths in the harsh under-hood environment. Automotive AEC-Q100 qualification, 3.0-3.6 V operation from a 5V-regulated bus, and the 28-QFN footprint allow a compact, fully-sealed pump housing. The PTG (Peripheral Trigger Generator) offloads ADC-trigger timing from the CPU for deterministic current sampling.
Рекомендуется
Industrial Servo / Small Stepper Drive
Industrial servo and small stepper drives benefit from the PIC24EP32MC202-E/MM's deterministic PIC24E core and DSP-class instructions. With 60 MIPS throughput, the device executes closed-loop position control with feed-forward and PID updates at 10 kHz without timing jitter. The 12-bit ADC (up to 6 channels) reads encoder quadrature, analog command inputs, and motor current feedback. The 32 KB program memory holds a complete trapezoidal or s-curve motion profile library. The 28-QFN exposed pad provides sufficient thermal dissipation for the small industrial enclosures typical of 24V/48V servo drives.
Рекомендуется
E-Bike / Pedelec Motor Controller
E-bike and pedelec motor controllers require a compact MCU that delivers both real-time motor control and user-interface logic. The PIC24EP32MC202-E/MM runs at 60 MIPS, leaving cycles for torque-assist calculations, throttle processing, and battery-current monitoring while simultaneously driving a 3-phase BLDC hub motor. The three on-chip op-amps handle phase-current sensing; the comparators handle zero-crossing for sensorless starting. The 28-QFO exposed-pad package and 32 KB Flash support a complete pedelec firmware stack including torque-assist tables and CAN-bus diagnostics. Extended -40 °C to +125 °C operation tolerates outdoor mounting on the bike frame.
Рекомендуется
Drones / Quadcopter ESC (Electronic Speed Controller)
Small-to-medium drone ESCs use the PIC24EP32MC202-E/MM for fast, deterministic motor control. The MCPWM module supports 24 kHz PWM with programmable dead-band, and the 60 MIPS PIC24E core runs sensorless or sensored commutation at the 8 kHz typical rate. With only 32 KB Flash and 4 KB RAM, the device targets compact 4-in-1 ESC boards where four instances of this MCU each drive a separate motor. The 28-QFN 6x6 mm footprint is small enough for high-density PCB layouts, and the on-chip op-amps reduce the bill of materials by eliminating external current-sense ICs.
Рекомендуется
Home Appliance Variable-Frequency Motor (Washer / Compressor)
White-goods variable-frequency drives - washing machines, dishwasher pumps, refrigerator compressors - leverage the PIC24EP32MC202-E/MM's integrated analog and motor-control peripherals. The on-chip op-amps handle single- or three-shunt current sensing, while the comparators handle overcurrent and desaturation protection. The 60 MIPS performance executes FOC with active PFC for IEC 61000-3-2 compliance in variable-speed compressor drives. AEC-Q100 grade is overkill for indoor appliances but is a useful proxy for long-term reliability. The 28-QFN exposed pad meets the thermal envelope of a sealed compressor compartment.

Заметки по проектированию
Estimated: at typical motor-control workload (CPU active ~70%, peripherals on), the device draws ~25 mA from VDD, dissipating ~90 mW at 3.3 V. The 28-QFN exposed pad has a theta_JA of approximately 35 °C/W with a minimum-recommend PCB footprint (4 thermal vias to inner ground plane); junction rise is therefore ~3 °C above ambient - well within the +125 °C limit. Recommended: stitch the EP to a continuous ground pour with at least 6 thermal vias in a 3x2 grid.
Place one 100 nF X7R 0402 ceramic decoupling capacitor within 3 mm of VDD (pin 27), and one 100 nF ceramic within 3 mm of AVDD (pin 19). Keep analog traces (AN0-AN5, op-amp inputs) away from PWM switching traces to avoid capacitive coupling; route AVDD/AVSS as a dedicated analog island joined to digital ground at a single point under the IC. The exposed pad must be soldered for thermal and electrical performance - do not leave it floating.
Do not exceed the absolute maximum VDD of 3.6 V; the device is NOT 5V-tolerant on any I/O pin. When programming via ICSP, ensure MCLR voltage does not exceed VDD + 0.3 V during operation. The MCPWM fault input (FLT1) must be configured with a valid pull-down or driven low before enabling PWM outputs, otherwise outputs stay tri-stated. Configure unused comparators and op-amps to disabled state in firmware to avoid quiescent current leakage.
