PIC24FJ32MC104-E/PT Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (RAM), and a rich set of peripherals such as timers, ADC, communication interfaces, and I/O ports on one die. Within the broader embedded hierarchy, this part belongs to the 16-bit MCU class -> microcontroller -> embedded processor -> semiconductor IC. Motor-control MCUs like the PIC24FJ32MC104 extend the general-purpose MCU concept by adding dedicated PWM generators, fast ADC, and analog comparators that close the loop around power-converter or motor-driver stages.
Key features include three 16-bit MCPWM (Motor Control PWM) channels with complementary outputs and programmable dead-time, a 10-bit ADC with at least 500 ksps conversion rate, three on-chip analog comparators for back-EMF or current sensing, a Charge Time Measurement Unit (CTMU) for capacitive touch or temperature sensing, Peripheral Pin Select (PPS) for flexible signal routing, and a Real-Time Clock and Calendar (RTCC) with calendar mode. The 16 MIPS core runs most instructions in one cycle, giving deterministic control-loop timing for sensorless and sensored BLDC/PMSM drives.
Architecturally the device uses a 16-bit modified-Harvard RISC core with a 24-bit instruction word, a hardware multiplier for single-cycle MAC operations, and direct memory-mapped peripheral access. The MCPWM block supports edge-aligned, center-aligned, and variable-phase PWM, which is essential for field-oriented control. PPS allows remapping of digital peripherals to most I/O pins, simplifying PCB layout and reducing routing congestion.
Typical applications include 3-phase BLDC and PMSM motor drives, sensored and sensorless fan and pump controllers, low-cost ceiling fans, e-bike and e-scooter controllers, appliance motor control boards, and general industrial automation. The -E extended temperature and AEC-Q100 qualification also support automotive body and HVAC actuators.
Designers should budget for the external analog supply filter and ensure the on-chip voltage regulator is decoupled with at least a 10 uF bulk plus a 0.1 uF ceramic capacitor close to the VDD/VSS pair. PWM dead-time programming should be set greater than the power-stage turn-off delay to avoid shoot-through in half-bridge drivers.
This page synthesizes distributor pricing, drop-in same-family alternatives, AEC-Q100 qualification notes, and practical design considerations that go beyond the manufacturer datasheet summary.

Applications typiques
PIC24FJ32MC104-E/PT convient pour 7 applications: 3-Phase BLDC Motor Drive, Sensored PMSM / Field-Oriented Control, Ceiling Fan and HVAC Fan Controller, Low-Voltage Servo / RC Motor Controller, Industrial Pump and Valve Actuator, E-Bike and E-Scooter Motor Controller, Capacitive Touch User Interface.
3-Phase BLDC Motor Drive
The PIC24FJ32MC104-E/PT drives small 3-phase brushless DC (BLDC) motors in appliances, fans, and pumps with up to ~1 kW rating. Its 3 MCPWM channels provide complementary 16-bit PWM outputs with programmable dead-time, eliminating shoot-through in half-bridge MOSFET or IGBT stages. The 3 on-chip analog comparators perform back-EMF zero-crossing detection for sensorless commutation or current-limit feedback for cycle-by-cycle protection. At 32 MHz and 16 MIPS, the CPU executes sensorless trapezoidal and field-oriented control (FOC) loops inside the PWM period, while the 32 KB Flash stores the state machine and tuning tables. The AEC-Q100 -E grade suits under-hood automotive applications and industrial inverters.
Recommandé
Sensored PMSM / Field-Oriented Control
For sensored PMSM drives using Hall sensors or encoders, the PIC24FJ32MC104-E/PT captures rotor position via interrupt-on-change inputs and generates synchronized SVM waveforms from the 3 MCPWM blocks. The 16 MIPS core is sufficient to run a Clarke-Park transform, PI current loop, and space-vector modulator at 8-20 kHz switching frequency. PPS routes the PWM outputs and QEI inputs to any digital I/O, simplifying PCB layout for compact motor-control boards. The 10-bit ADC reads phase currents through shunt resistors with sufficient resolution for low-cost FOC, while the 32 KB Flash holds sensor calibration tables and speed PI loops for HVAC compressors and e-bike drives.
Recommandé
Ceiling Fan and HVAC Fan Controller
The PIC24FJ32MC104-E/PT targets cost-sensitive AC or BLDC ceiling-fan controllers where its MCPWM delivers smooth speed control from 0 to 1500 RPM. The 3 analog comparators detect zero-crossings of the AC line or back-EMF of the BLDC stator, allowing simple commutation logic in 32 KB of Flash without external DSP. CTMU adds capacitive touch support for fan speed buttons, eliminating mechanical switches and improving the user interface. The AEC-Q100 qualification and -40C to +125C operation handle rooftop HVAC and outdoor fan installations. Power dissipation is minimal because the part is in a small 44-pin TQFP with low-power sleep modes below 20 uA.
Recommandé
Low-Voltage Servo / RC Motor Controller
For hobby-grade and industrial RC servos, the PIC24FJ32MC104-E/PT generates up to 3 channels of high-resolution PWM (1 us to 2 ms pulse widths) to command digital servos with sub-millisecond repeatability. The 16-bit PWM timer clocked at 32 MHz gives 488 ns PWM resolution, supporting smooth gimbal and robot-axis motion. UART and I2C interfaces connect to host MCUs or RC receivers, while RTCC keeps time-of-day for logging applications. The 2 KB SRAM is sufficient for trajectory tables and PID setpoints without external memory. Automotive qualification also makes this part a candidate for body-electronics actuators.
Recommandé
Industrial Pump and Valve Actuator
In industrial pumps, dosing pumps, and proportional valves the PIC24FJ32MC104-E/PT replaces older 8-bit MCUs by delivering deterministic 3-phase PWM, accurate ADC sampling, and industrial communication interfaces in a single chip. The 32 KB Flash stores Modbus or CANopen handling logic, while RTCC schedules pump cycles for water-treatment and process-control plants. The AEC-Q100 -E grade tolerates the -40C to +125C environment near hydraulic cabinets and outdoor installations. CTMU provides capacitive water-level detection, and the on-chip comparators protect against dry-running by sensing motor current. The wide AEC-Q100 stress margin extends equipment MTBF.
Recommandé
E-Bike and E-Scooter Motor Controller
Light electric vehicles such as e-bikes and e-scooters use the PIC24FJ32MC104-E/PT to drive 24-48 V BLDC hub or mid-drive motors up to ~500 W. The 3 MCPWM channels produce the 3-phase gate signals, the analog comparators monitor battery current for cut-off protection, and the ADC reads throttle position and brake levers. AEC-Q100 qualification gives confidence in vibration, thermal, and surge environments encountered on-road. PPS lets the same hardware serve 6-FET or 3-FET inverter topologies by remapping PWM outputs. RTCC timestamps ride data into a small external EEPROM for diagnostics, and the 32 KB Flash stores 6-step or FOC firmware for up to 4 riding modes.
Recommandé
Capacitive Touch User Interface
The CTMU peripheral inside the PIC24FJ32MC104-E/PT simplifies capacitive touch-button implementation for appliances and industrial HMIs, eliminating dedicated touch ICs. The CTMU measures capacitance changes on up to 32 channels with sub-pF resolution, supporting sliders, wheels, and proximity wake-up. Combined with the on-chip RTCC, designers can build user interfaces with timed backlight dimming, while the ADC and analog comparators monitor other analog signals on the same board. The -E temperature grade suits outdoor EV charging-station panels and solar inverter keypads. 2 KB SRAM and 32 KB Flash comfortably host capacitive-touch libraries plus a basic UI state machine.

- Same TQFP-44 footprint across the MC104 family simplifies PCB reuse (vs PIC24FJ32MC102 (28-pin SSOP))
- Dedicated MCPWM + 3 analog comparators + CTMU in one MCU (vs dsPIC33FJ16MC102-I/PT (DSP MCU))
Notes de conception
Decouple the PIC24FJ32MC104-E/PT VDD/AVDD pins with a 10 uF bulk plus 0.1 uF ceramic capacitor placed within 5 mm of each supply pin. The on-chip voltage regulator powers the digital core from VDD; a clean supply is critical because the 16 MIPS core and 10-bit ADC both draw transient current when the PWM module and ADC fire simultaneously. Add a ferrite bead between VDD and AVDD if the analog inputs measure small signals.
Route the PWM output traces as short and symmetric as possible from the PIC24FJ32MC104-E/PT to the gate-driver inputs. Each PWM transition has 16-bit resolution down to 61 ns at 32 MHz, so layout-induced skew can break dead-time and cause shoot-through in the half-bridge. Keep PWM traces away from analog input traces by at least 3x the trace-to-trace spacing to minimize capacitive coupling.
Estimated: at 32 MHz, 3.3 V VDD, and full peripheral activity, the PIC24FJ32MC104-E/PT draws ~30 mA active, dissipating ~100 mW. The 44-pin TQFP (PT) thermal resistance theta_JA is approximately 45 C/W on a 4-layer JEDEC test board, yielding a junction temperature rise of ~4.5 C above ambient. The -E grade (125 C maximum) easily accommodates this in sealed enclosures, but derate for high ambient temperatures above 85 C in outdoor motor cabinets.
Do not leave the MCLR pin floating on the PIC24FJ32MC104-E/PT - it must be pulled high through a 10 kOhm resistor to VDD for normal operation, and adding a 100 nF capacitor to ground creates an optional manual-reset pushbutton input. Forgetting PPS configuration is another common mistake: digital peripherals default to specific pins, and the PWM outputs and QEI inputs may need remapping in software before they appear on the desired physical I/O pins.
