PIC24HJ32GP202-I/SP 概要
A 16-bit microcontroller is a microprocessor whose data path, registers and ALU are 16 bits wide, offering roughly 2-4x the arithmetic throughput of 8-bit MCUs at the same clock frequency. The PIC24H family sits in Microchip's mid-range 16-bit portfolio above the PIC24F and below the dsPIC33 family. PIC24H parts share the dsPIC33F instruction set, making them ideal for control applications that demand high-speed, repetitive computations such as motor control, power conversion and digital signal preprocessing.
The PIC24HJ32GP202 integrates 2KB of RAM, 21 general-purpose I/O pins, three 16-bit timers/counters (pairable into one 32-bit timer), two output capture modules and two PWM modules. Hardware peripherals include a 16-channel 10-bit 500 ksps ADC, two UART modules, two SPI interfaces and one I2C port. The CPU is a Harvard-architecture modified RISC engine with single-cycle 16x16 multiplication, zero-overhead looping and a four-deep instruction queue.
Typical applications include industrial motor control (BLDC/PMSM sensorless drives), digital power conversion (PFC, LLC, full-bridge SMPS), sensor signal conditioning, automotive body and chassis ECUs, and consumer appliances requiring deterministic real-time control. The 40 MIPS core handles 100 kHz+ PWM loops while leaving headroom for communication stacks.
When designing with this device, place a 10uF tantalum plus 0.1uF ceramic decoupling capacitor pair adjacent to each VDD/VSS pin pair. Maintain trace lengths below 25 mm on the external 8 MHz crystal routing to the OSC1/OSC2 pins to prevent EMI under normal switching.

主な用途
PIC24HJ32GP202-I/SP の用途: 7 件s: BLDC / PMSM Motor Control, Digital Power Conversion (PFC + LLC), Industrial Sensor Signal Conditioning, Automotive Body Electronics ECU, Consumer Appliance Control Boards, Data Acquisition and Control Module, Building Automation (HVAC, Lighting).
BLDC / PMSM Motor Control
The PIC24HJ32GP202-I/SP is well suited for sensorless BLDC and PMSM motor control at switching frequencies of 20-100 kHz. Its 40 MIPS core executes field-oriented control (FOC) and space-vector PWM loops well within one PWM period, while the two PWM modules and three 16-bit timers provide the hardware backbone for complementary PWM outputs with programmable dead-time insertion. The 16-channel 10-bit 500 ksps ADC samples back-EMF and phase currents with sufficient bandwidth for low-RPM sensorless startup. The 3.0-3.6V supply integrates cleanly with 3.3V gate-driver ICs such as the Microchip MCP8024 or DRV8301.
おすすめ
Digital Power Conversion (PFC + LLC)
The PIC24HJ32GP202-I/SP supports digital control loops for PFC, LLC and full-bridge SMPS topologies where deterministic loop timing is critical. Its 40 MIPS core executes a 100 kHz voltage-mode control loop in under 25 percent CPU load, leaving headroom for housekeeping and communication. The two PWM outputs with programmable dead-time and fault shutdown provide direct control of synchronous rectifiers, while the high-speed 10-bit ADC samples output voltage and current at 500 ksps with 1.5 us conversion latency. Internal Flash self-programming enables in-field firmware updates for power-supply firmware revisions.
おすすめ
Industrial Sensor Signal Conditioning
The PIC24HJ32GP202-I/SP conditions analog inputs from industrial sensors (RTD, thermocouple, strain gauge, 4-20 mA loops) and bridges them to UART/SPI for PLC backplanes. Its 16-channel 10-bit ADC scans multiple sensor inputs within a 32 ms window, while the hardware UART and SPI peripherals offload serial-protocol framing from the CPU. The 32 KB Flash accommodates lookup tables for linearization and cold-junction compensation. The 3.0-3.6V supply draws typically 60 mA at full CPU load, suitable for loop-powered 24V-to-3.3V designs with adequate headroom under normal switching conditions.
おすすめ
Automotive Body Electronics ECU
The PIC24HJ32GP202-I/SP handles body-electronics ECUs (window lift, seat control, HVAC blower, lighting controllers) that benefit from the -40 to +85 C industrial operating range. Its two PWM modules drive LED arrays and DC-motor H-bridges, while the two UART ports interface LIN bus and K-line diagnostics to the central BCM. The 32 KB Flash and 2KB RAM accommodate CAN/LIN J1939 stacks plus local control logic. Pairing with a TJA1027 LIN transceiver creates a fully LIN-2.x-compliant slave node with adequate margin for typical automotive body workloads.
おすすめ
Consumer Appliance Control Boards
The PIC24HJ32GP202-I/SP drives white-goods controllers in washing machines, dishwashers and induction cooktops where 16-bit math and reliable I/O are needed. Its three 16-bit timers (pairable into a 32-bit timer) generate precise dosing cycles, while the two PWM outputs control induction heating elements at 20-50 kHz switching frequency. The 21 GPIO pins interface directly to keypad matrix, LED indicators, and triac-trigger optocouplers. The 28-pin SPDIP package remains hand-solderable for low-volume appliance runs and field-repairable designs.
おすすめ
Data Acquisition and Control Module
The PIC24HJ32GP202-I/SP forms the heart of a multi-channel data-acquisition front end that converts analog sensor streams to USB/UART data for host PCs. Its 16-channel ADC, two UART and two SPI peripherals support simultaneous acquisition, GPS time-stamping and SD-card logging through SPI bridges. The 40 MIPS core manages real-time timestamped sample queues at 10 kHz aggregate sample rate. Self-programming Flash supports field deployment of calibration coefficients and firmware upgrades via bootloader.
おすすめ
Building Automation (HVAC, Lighting)
The PIC24HJ32GP202-I/SP executes HVAC zone-controller and DALI-lighting logic in commercial building automation networks. Its two UART ports interface to BACnet MS-TP and Modbus RTU trunks, while two PWM outputs drive 0-10V analog dimming channels. The 32 KB Flash accommodates BACnet/Modbus object dictionaries and DALI-2 application controller logic. The industrial -40 to +85 C range handles unconditioned mechanical-room environments without additional thermal management, and the 28-pin SPDIP package remains serviceable for field technicians.

設計ノート
Estimated power-supply decoupling: place a 10 uF tantalum plus 0.1 uF ceramic pair adjacent to each VDD/VSS pin pair (pins 13/19 and AVDD 27/AVSS 28). The PIC24HJ32GP202-I/SP draws up to ~60 mA at 40 MIPS full CPU load per the datasheet, so use a regulator with at least 100 mA headroom. Ferrite bead between digital and analog supply rails prevents ADC noise coupling under normal switching conditions.
Keep the external crystal traces to OSC1 (pin 9) and OSC2 (pin 10) under 25 mm and surround them with a ground guard ring to minimize EMI pickup. Place the crystal within 10 mm of the MCU, with both load capacitors (typically 18-33 pF) returned to the analog ground plane. Keep the ICSP/ICD pins (PGED1/PGEC1 on pins 4/5 and PGED2/PGEC2 on pins 18/20) accessible for in-circuit debugging headers.
MCLR (pin 1) requires a 10 kohm pull-up to VDD for normal operation; a floating MCLR pin causes intermittent reset behavior. The internal band-gap voltage reference may need external bypass on the VREF+/VREF- pins (2/3) for ADC accuracy better than +/- 2 LSB. Peripheral Pin Select (PPS) remapping must be configured before the first I/O use or peripheral functions will not appear at the expected pins.
