PIC24EP256MC202-H/MM - 60 MIPS 16-bit Motor Control MCU | Microchip
MPN: PIC24EP256MC202-H/MM ✓ Hoạt độngPIC24EP256MC202-H/MM Tóm tắt
A microcontroller (MCU) is an integrated circuit containing a processor core, program and data storage, and a rich set of programmable peripherals on a single die. The PIC24E family belongs to the dsPIC/PIC24 digital-signal-controller hierarchy, sitting between general-purpose PIC MCUs and the dsPIC33 high-performance DSC line. These devices are optimized for deterministic real-time control, where the CPU, on-chip peripherals, and interrupt structure are co-designed to deliver guaranteed latency for closed-loop tasks such as commutation, current sensing, and power-converter switching.
Key differentiating features of the PIC24EP256MC202-H/MM include 60 MIPS execution from a 3.0 V to 3.6 V supply, 256 KB self-programmable Flash with ECC-style robustness in the PIC24E architecture, six high-speed PWM channels with 1.04 ns PWM resolution suitable for 100 kHz+ switching frequencies, and integrated operational amplifiers that eliminate external analog front-end circuitry for current shunt amplification. The '-H' suffix denotes the high-temperature automotive grade variant qualified to AEC-Q100, supporting operation across the extended -40 °C to +150 °C junction range, while the '/MM' suffix designates the 28-pin QFN-S package.
Architecturally, the device uses a 16-bit modified-Harvard core with a 24-bit instruction word, dual address/data buses, and a 16-element working register array. The peripheral set includes multiple UART, SPI, I2C, and CAN interfaces, plus 12-bit ADC converters with dedicated sample-and-hold and dual analog comparators, enabling the part to handle both digital communication and high-bandwidth analog feedback within a single chip.
Typical applications include BLDC/PMSM motor drives, low-voltage industrial fans and pumps, automotive cooling and pump controllers, sensored and sensorless FOC inverter stages, and compact stepper/servo amplifiers. The combination of integrated op-amps, high-resolution PWM, and AEC-Q100 qualification makes the PIC24EP256MC202-H/MM particularly well-suited for cost-sensitive automotive motor-control ECUs where PCB area and BOM count must be minimized.
When designing with this MCU, allocate at least one ceramic bypass capacitor pair (100 nF + 10 µF) directly at the VDD/VSS pins and a separate pair at the AVDD/AVSS pins to keep ADC and op-amp noise isolated from digital supply transients. Verify PWM update rate and dead-time settings against your MOSFET/IGBT driver's propagation delay to avoid shoot-through at high duty cycles.

Ứng dụng tiêu biểu
PIC24EP256MC202-H/MM phù hợp cho 6 Áp dụngs: BLDC/PMSM Motor Control, Automotive Cooling Fans, Electric Water/Oil Pumps, Industrial Servo Amplifiers, Sensorless Drone ESCs, Home Appliance Compressors.
BLDC/PMSM Motor Control
The PIC24EP256MC202-H/MM is purpose-built for brushless DC and permanent-magnet synchronous motor control. Its 60 MIPS core, six high-speed PWM channels with 1.04 ns edge resolution, and on-chip operational amplifiers (used as current-sense preamps) enable field-oriented control (FOC) and sensorless back-EMF commutation. The 256 KB Flash fits full FOC state-machine code plus sensorless startup tables, and the AEC-Q100 qualification supports automotive pumps and HVAC blowers. Place the integrated op-amp outputs directly into the ADC inputs for sub-microsecond current-loop sampling.

Automotive Cooling Fans
In 12 V/24 V automotive cooling fan modules, the PIC24EP256MC202-H/MM drives a 3-phase inverter switching at 20-40 kHz with closed-loop speed control. The AEC-Q100 -H grade handles underhood temperatures up to +150 C junction. Its integrated op-amps read shunt-resistor current for stall detection, while the 16 KB SRAM holds the PI speed-controller state. The 28-QFN-S (6x6 mm) footprint fits inside the fan hub assembly alongside the inverter power stage.

Electric Water/Oil Pumps
For 12 V/48 V automotive coolant and oil pumps, the PIC24EP256MC202-H/MM runs sensored FOC on a small BLDC motor while the CAN peripheral interfaces with the vehicle body controller. The device's 60 MIPS budget handles vector math, speed ramping, and CAN diagnostics in a single core. Its automotive temperature grade (-40 C to +150 C) covers underhood ambient, and the 28-QFN package enables a compact PCB that fits inside the pump housing.
Được đề xuất
Industrial Servo Amplifiers
In low-voltage industrial servo amplifiers (24-48 V DC bus), the PIC24EP256MC202-H/MM drives stepper or small PMSM motors with quadrature encoder feedback through its QEI module. The high-speed PWM generates the sinusoidal commutation profile, while the 12-bit ADC samples the encoder index and current shunts in tandem. While the -H grade is automotive-qualified, the device is commonly used in industrial servo designs when a single part covers both markets and simplifies inventory.
Được đề xuất
Sensorless Drone ESCs
In small/medium drone electronic speed controllers (ESCs), the PIC24EP256MC202-H/MM drives a 4-in-1 BLDC inverter with sensorless zero-crossing commutation. The 256 KB Flash stores zero-crossing detection tables and the 60 MIPS core runs the commutation loop at up to 50 kHz. The 28-QFN-S footprint (6x6 mm) is small enough for sub-20 A ESC boards. Note that for hobby-grade drones the industrial -I grade would be sufficient and cheaper.

Home Appliance Compressors
For inverter-driven refrigerator compressors and washing-machine drum motors, the PIC24EP256MC202-H/MM provides the control core for variable-speed BLDC/PMSM compressors using sensorless FOC. The 256 KB Flash accommodates compressor-specific start/stop ramps and protection algorithms. The integrated op-amps interface with current shunts to detect stall conditions, and CAN/UART provide the appliance bus interface. The 28-QFN-S footprint allows a compact control board that fits inside the compressor terminal box.

Ghi chú thiết kế
The 28-pin QFN-S exposes its die pad on the bottom of the package for heat removal. Always solder this exposed pad to a continuous PCB ground copper pour, ideally with thermal vias stitching the top pour to inner/ground planes. Estimated: with 60 MIPS and 3.3 V core supply, the MCU draws ~30 mA active, so power dissipation is ~100 mW - well within the 28-QFN thermal envelope. Even at +125 C ambient, junction temperature stays well under the +150 C AEC-Q100 limit, but adequate copper pour is still required for long-term reliability.
Place a 100 nF ceramic bypass capacitor within 3 mm of every VDD/VSS pin pair and a 10 µF bulk capacitor at the regulator output feeding AVDD. The PIC24E's 12-bit ADC and integrated op-amps draw microamp-level currents but are sensitive to switching-noise on the analog supply; routing AVDD through a ferrite bead from the digital VDD is a common noise-isolation technique. Estimated: at 60 MHz FOSC, the core draws ~30 mA from VDD - the 100 nF + 10 µF pair provides sufficient decoupling for normal operation.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kΩ pull-up and use the standard Microchip in-circuit debug (ICD) header pinout for production programming access. When using the integrated op-amps for current sensing, calibrate the offset at startup using the MCU's internal DAC/calibration routine, otherwise the motor will cog at low speeds due to current offset. Avoid using the same ADC channel for both op-amp output and a digital input - the channel mux architecture can introduce cross-talk during simultaneous sampling.
Keep the high-speed PWM output traces (RB0-RB5 on this package) short and direct to the gate driver. Route PWM traces away from the analog op-amp inputs (RA0-RA4) to minimize capacitive coupling that can inject switching noise into the current-sense signal. Use a 4-layer PCB stack-up with a dedicated ground plane under the MCU; the exposed pad of the 28-QFN should have at least 8 thermal vias (0.3 mm drill) into the inner ground plane to keep junction temperature below +150 C at full load.
