A 16-bit microcontroller (MCU) is an embedded processor that executes instructions on 16-bit data paths, occupying the middle ground between 8-bit MCUs (PIC16, AVR) and 32-bit Cortex-M parts. Within the broader taxonomy, the PIC24H belongs to the dsPIC/PIC24 family -> 16-bit microcontroller -> embedded MCU -> microcontroller IC -> semiconductor. The “H” sub-series adds DMA and a hardware multiplier, giving the PIC24H deterministic real-time response and signal-processing throughput that 8-bit MCUs cannot deliver at comparable code density.
The PIC24HJ64GP202-E/MM offers 8-channel DMA, a 16-channel 12-bit ADC with 500 ksps throughput, and dedicated motor-control PWM peripherals. It is pin-compatible with the dsPIC33F family, allowing migration to DSP-enabled parts without PCB rework. The 28-QFN exposed pad lowers junction-to-ambient thermal resistance, enabling higher continuous CPU throughput at elevated ambient temperatures. An integrated 8 MHz internal oscillator reduces BOM cost, while the on-chip 16-bit timer/counter block supports three independent timers that can be paired into one 32-bit timer.
Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion (SMPS, PFC, LLC), sensor signal conditioning and sensor-fusion front ends, automotive body and chassis ECUs (where -E grade is mandatory), and high-performance sensor hubs. The DMA-driven 12-bit ADC also suits data-acquisition front-ends and predictive-maintenance vibration monitoring.
When designing with this MCU, place a 100 nF decoupling capacitor at each VDD/AVDD pin and a 10 uF bulk capacitor near the exposed pad. The exposed pad MUST be soldered to a continuous ground plane for thermal dissipation and EMI performance. The PIC24HJ64GP202-E/MM is a member of Microchip’s Classic 16-bit PIC24H portfolio, which is pin-compatible with PIC24FJ and dsPIC33F devices in the same package.

典型應用
PIC24HJ64GP202-E/MM 適用於 6 應用s: BLDC/PMSM Motor Control (FOC), Digital Switched-Mode Power Supply (SMPS), Industrial Sensor Hub / Data Acquisition, Automotive Body and Chassis ECU, Industrial Control PLC / Remote I/O, Consumer Audio DSP / Effects Processor.
BLDC/PMSM Motor Control (FOC)
The PIC24HJ64GP202-E/MM is well suited for sensorless and sensored FOC of three-phase BLDC and PMSM motors up to several hundred watts. Its 40 MIPS throughput runs the Park/Clarke transforms and PI loops within a single PWM period, while the dedicated motor-control PWM with complementary outputs and dead-band generation drives a 3-phase half-bridge directly. The 8-channel DMA autonomously transfers ADC current samples into RAM, leaving the core free for control math, and the 12-bit ADC at 500 ksps captures dual shunt currents synchronously to the PWM. Typical firmware (Microchip AN1078) drops in unmodified, allowing field-proven 6-step trapezoidal, sine, and FOC commutation. The -40C to +125C operating range permits under-hood automotive and outdoor industrial cabinet designs without additional thermal management.
推薦
Digital Switched-Mode Power Supply (SMPS)
The PIC24HJ64GP202-E/MM drives digital-control SMPS topologies including PFC, LLC, phase-shifted full-bridge and synchronous buck/boost converters. Its 40 MIPS throughput executes the voltage-mode and average-current-mode control loops within 25 us switching periods typical of 40 kHz converters. The dedicated 16-bit PWM with 8.3 ns resolution sets switching frequency and duty cycle, while the high-speed 12-bit ADC samples input/output voltage and current synchronously to the PWM edge. The DMA moves ADC samples into RAM and triggers the control ISR with deterministic latency. The -E temperature grade supports telecom and industrial PSUs that must operate above 70 C ambient. Microchip AN1114 digital-power firmware and the DPW library accelerate code development.
推薦
Industrial Sensor Hub / Data Acquisition
The PIC24HJ64GP202-E/MM functions as a multi-sensor data-acquisition front-end for predictive maintenance, vibration monitoring and process control. Its 16-channel 12-bit ADC captures strain-gauge, RTD, thermocouple and 4-20 mA current-loop signals, while the 8-channel DMA streams samples to RAM without CPU load. Dual SPI at up to 10 MHz simultaneously digitizes external sigma-delta ADCs for high-precision channels. The dual UART bridges to RS-485 / Modbus slaves, and the I2C peripheral reads digital temperature sensors and EEPROMs. The 8 KB RAM buffers FFT frames for on-chip vibration analysis, while the 64 KB Flash stores sensor-conditioning tables. The -40C to +125C grade supports factory-floor and outdoor installations.
推薦
Automotive Body and Chassis ECU
The PIC24HJ64GP202-E/MM's -40C to +125C operating range and EMC-robust design suit under-hood and chassis body ECUs including HVAC damper control, seat-position memory, mirror-fold, lighting ballast and window-lift modules. Its 21 I/O drive LEDs, H-bridges and relay coils directly through external FETs. Dual CAN is not integrated; the MCU pairs with an external MCP2515 CAN controller over SPI for body-network connectivity. The 12-bit ADC reads position potentiometers, current shunts and battery voltage, while the 16-bit timers generate PWM for servos and lighting. The 64 KB Flash accommodates J1939 and OBD-II diagnostic stacks, and 8 KB RAM supports OSEK/Autosar-lite schedulers.
推薦
Industrial Control PLC / Remote I/O
The PIC24HJ64GP202-E/MM serves as a compact industrial controller for small-form-factor PLCs, remote I/O slices and protocol-bridge gateways. Its dual UART bridges Modbus RTU and proprietary field buses, while the I2C port reads HMI displays and EEPROM configuration. The 21 I/O drive 24 V opto-isolated inputs and outputs through external circuitry. The 40 MIPS core runs ladder-logic interpreters and PID loops, and the 64 KB Flash hosts Modbus, EtherNet/IP lite or BACnet stacks. The -E temperature grade and QFN exposed pad permit DIN-rail mounting in sealed cabinets with no active cooling. Industrial EMC/Signal integrity is enhanced by the MCU's hardware DMA that offloads deterministic timing-critical tasks from the core.
推薦
Consumer Audio DSP / Effects Processor
The PIC24HJ64GP202-E/MM provides sufficient throughput for low-cost digital audio processing such as guitar-effects pedals, multi-channel mixers and karaoke reverb/echo units. The dsPIC33F variant enables FFT-based spectrum analysis and pitch detection. I2S data is captured via the SPI peripheral with DMA, and the 12-bit ADC serves as a control-voltage input for analog knobs. The 64 KB Flash stores multiple effect presets, while the 8 KB RAM buffers audio frames. The 28-QFN footprint fits inside compact pedal enclosures, and the -40C to +125C grade tolerates stage lighting and outdoor temperatures.

設計說明
Place a 100 nF decoupling capacitor on each VDD pin (pin 15 and pin 28) and a 10 uF bulk tantalum or ceramic capacitor near the exposed pad (EP) on the QFN package. A separate 100 nF decoupling capacitor on the AVDD pin (pin 16) isolates analog supply noise from the digital core. Estimated: with the 28-QFN 6x6 mm package and a 4-layer PCB with continuous ground plane, VDD ripple stays below 50 mVpp at 40 MIPS with full peripheral activity, meeting ADC SNR spec of 69 dB at full bandwidth.
The QFN-28 exposed pad MUST be soldered to a continuous ground plane with multiple thermal vias (typically 9-16 vias of 0.3 mm drill on a 1.0 mm grid) to dissipate the 100 mA core current at 40 MIPS. Without proper EP soldering, junction temperature can rise above +125 C and trigger thermal shutdown. Estimated: with a 4-layer JEDEC EIA/JESD51 test board, theta_JA is approximately 40 C/W; with optimal thermal via array it can drop to 28 C/W, enabling reliable +125 C operation at full load.
Route the crystal traces (OSC1 pin 7, OSC2 pin 8) symmetrically with ground guard traces on both sides and keep the crystal within 5 mm of the MCU to minimize stray capacitance. Place the crystal capacitors (typically 15-33 pF) directly between each OSC pin and ground. JTAG traces (TMS/TCK/TDI/TDO pins 11-14) should be length-matched to within 25 mm if used at high debug clock rates. The ICSP programming pins (PGED2/PGEC2 pins 4-5) require no length matching since they are typically only used during production.
Do not exceed 3.6 V on any VDD pin - the on-chip brown-out reset trips between 2.95-3.0 V and Flash programming is inhibited below 3.0 V. Always configure unused I/O pins as outputs driven low to minimize current draw. The MCLR pin (pin 1) requires a 10 kohm pull-up to VDD; do not leave it floating. When migrating from PIC24HJ64GP202 to dsPIC33FJ64GP202, change the device header in MPLAB X but verify that the dsPIC's DSP instructions do not collide with PIC24 instruction encodings.
The 12-bit ADC achieves 69 dB SNR only when the analog supply (AVDD pin 16) is filtered with a ferrite bead from VDD and decoupled with a 10 uF + 100 nF network. Route analog signals (AN0/AN1 pins 2-3) away from PWM outputs and clock traces to avoid digital switching noise coupling into ADC samples. Enable the DMA to move ADC results to RAM automatically - this reduces interrupt latency jitter and improves effective ADC SNR by 3-5 dB compared to CPU-driven sampling.
