PIC24FJ32MC102-E/SO 概要
A 16-bit microcontroller (MCU) is an embedded processor whose internal datapath, registers, and arithmetic logic unit operate on 16-bit words. Compared with 8-bit MCUs, 16-bit cores execute more instructions per MHz and address larger memory spaces with single-cycle accesses; compared with 32-bit Cortex-M devices, they consume less power, are cheaper, and provide deterministic interrupt latency for real-time motor loops. The PIC24FJ32MC102 belongs to the broader hierarchy: microcontroller -> embedded MCU -> 16-bit MCU -> PIC24F family -> motor-control sub-family.
Key features include a wide operating voltage range of 3.0 V to 5.5 V (typical 3.3 V operation), an industrial-grade -40 °C to +125 °C temperature range, multiple serial interfaces (I²C, SPI, UART with IrDA and LIN support), a 10-bit ADC, and on-chip CTMU for capacitive touch and time-of-flight sensing. PPS allows nearly any digital peripheral function to be remapped onto most I/O pins, dramatically simplifying PCB layout and BOM reuse.
Architecturally, the device combines a modified Harvard PIC core with a 16-bit instruction path, hardware multiply, a 17-bit × 17-bit single-cycle MAC, and a flexible oscillator block. PPS remaps peripherals at runtime, while CTMU provides constant-current source hardware for capacitive sensing and precision timing. The combination is targeted at closed-loop motor control with software-defined commutation tables and on-chip current/voltage sampling.
Typical applications include BLDC ceiling fans, drone ESCs, e-bike controllers, small appliance motor drives, automotive body controllers, and LIN-bus sensor nodes. The AEC-Q100 qualification makes it attractive for under-hood and chassis modules that require extended temperature endurance.
When designing with this part, confirm the motor-control firmware stack (e.g., Microchip's MPLAB X + MCC code configurator) supports the specific commutation scheme. Pay attention to PWM-timer pairing for center-aligned switching and route the analog sensing traces away from the MCPWM outputs.

主な用途
PIC24FJ32MC102-E/SO の用途: 6 件s: BLDC Motor Control (Ceiling Fans, Pumps, Appliances), Drone Electronic Speed Controllers (ESC), Automotive LIN Bus Sensor/Actuator Nodes, E-Bike / Small-EV Motor Controllers, Industrial Stepper Motor Drive, Small Appliance Motor Control (Mixers, Blenders, Vacuums).
BLDC Motor Control (Ceiling Fans, Pumps, Appliances)
The PIC24FJ32MC102-E/SO's MCPWM module delivers up to six PWM outputs with complementary and center-aligned modes, which is the canonical topology for sensorless trapezoidal or sinusoidal BLDC commutation. Its 32 KB Flash holds complete motor state-machine tables plus UART-based control links. With 16 MIPS, the device executes commutation lookups and ADC-triggered current sampling inside 1 µs, well within the 50 µs electrical period of a 4-pole 6000 RPM motor. AEC-Q100 qualification and -40 °C to +125 °C range suit appliance and automotive BLDC applications.
おすすめ
Drone Electronic Speed Controllers (ESC)
The PIC24FJ32MC102-E/SO fits small-form-factor ESCs that drive 4-in-1 BLDC motors up to 5 A. The 16 MIPS core runs 32 kHz PWM with dead-band insertion, while the 10-bit ADC samples phase currents synchronously to PWM edges via trigger-from-PWM. PPS lets designers reroute comparator and PWM outputs around PCB layout constraints, which is critical on the dense 4-quadrant ESC PCB. AEC-Q100 provides headroom for hobby-grade thermal excursions, while 28-SOIC stays hand-solderable for prototype tuning.
おすすめ
Automotive LIN Bus Sensor/Actuator Nodes
With LIN bus support on its UART plus AEC-Q100 qualification, the PIC24FJ32MC102-E/SO is well suited to body-electronics nodes such as seat adjusters, mirror controllers, and HVAC damper actuators. The 32 KB Flash comfortably holds a LIN 2.x slave stack plus custom application logic, while CTMU enables capacitive-button interface on the same die. PPS simplifies routing when the LIN PHY, motor outputs, and sense inputs must coexist on 28 pins.
おすすめ
E-Bike / Small-EV Motor Controllers
In e-bike pedal-assist and small-EV traction controllers, the PIC24FJ32MC102-E/SO drives a 36 V / 48 V BLDC hub motor via the MCPWM and reads throttle, torque, and cadence via ADC and CTMU. The 2 KB RAM is sufficient for state-machine plus current PI loops; 16 MIPS gives 1 µs loop time. AEC-Q100 ensures the controller survives road-temperature cycling. PPS allows pedal-cadence interrupt inputs to land on any spare pin, easing PCB layout.
おすすめ
Industrial Stepper Motor Drive
Two independent MCPWM channels can drive a bipolar stepper in full-step, half-step, or microstepping mode up to 32 kHz with deterministic phase advance. The PIC24FJ32MC102-E/SO's QEI input handles closed-loop position feedback, while the 10-bit ADC monitors motor current for stall detection. The 28-SOIC package is industry-standard for DIN-rail stepper modules and simplifies UL/CE certification paperwork.
おすすめ
Small Appliance Motor Control (Mixers, Blenders, Vacuums)
Small household appliances benefit from the PIC24FJ32MC102-E/SO's combination of MCPWM, CTMU for capacitive user-interface buttons, and LIN-capable UART for diagnostics. The 28-SOIC package drops into legacy appliance-control boards. AEC-Q100 qualification provides derating margin for hot-enclosure environments like steam irons or hair dryers. PPS allows designers to move PWM outputs to alternate pins if the PCB layout changes between appliance SKUs.

設計ノート
Place VDD/VSS decoupling capacitors (100 nF ceramic) within 5 mm of each VDD/VSS pin pair. Use a 10 µF bulk capacitor on the main VDD rail. The PIC24FJ32MC102-E/SO has two VDD and two VSS pins (pins 20/28 and 8/19) that MUST be decoupled locally. Route analog traces (RA0-RA4) away from PWM outputs (PPS-mappable on RB/RC) and away from the oscillator pins (OSC1/OSC2).
MCLR must be pulled up to VDD through a 10 kΩ resistor and have a 100 nF capacitor to VSS to suppress noise; a floating MCLR causes random resets in motor-control systems due to switching transients. Enable the internal MCLR pull-up only if hardware pull-up is present. Do not confuse PPS remapping - peripherals are mapped to physical pins only after unlocking the IOLOCK register via sequence-protected writes.
Estimated: at 32 MHz CPU clock and full I/O load, core consumption is approximately 30 mA from 3.3 V (≈100 mW). Junction temperature rise above ambient is roughly 100 mW × 90 °C/W = 9 °C in still air on a 28-SOIC board with 1 oz copper. Derate accordingly in enclosed motor-drive enclosures; AEC-Q100 grade only certifies silicon, not the PCB thermal design.
Keep the MCPWM output traces short and matched in length to avoid timing skew between high-side and low-side FETs in a 3-phase bridge. Use a ground island under the MCU separated from the high-current return of the bridge; bridge ground returns should be star-grounded at the bulk capacitor. Ferrite-bead or pi-filter VDD isolation from the noisy motor supply is recommended.
