PIC24HJ64GP504T-I/PT Overview
A 16-bit microcontroller (MCU) is an embedded processor that executes instructions on 16-bit data paths, offering a balance of computational throughput and code efficiency between 8-bit microcontrollers and 32-bit ARM Cortex-M parts. The PIC24H architecture extends this by adding DSP-friendly instructions and DMA, positioning it within the broader taxonomy of: microcontroller -> embedded processor -> semiconductor IC. It is commonly used in real-time control loops where deterministic execution and DSP math acceleration are required.
Key features of the PIC24HJ64GP504T-I/PT include up to 21 general-purpose I/O pins, 8KB of RAM, an 8-channel DMA controller, three 16-bit timers/counters that can pair into one 32-bit timer, two input capture modules, two output compare modules, and a 16-channel 10-bit/12-bit ADC. Communication peripherals include two UART, two SPI, and one I2C interface, plus a CAN 2.0B module. The device operates from 3.0V to 3.6V, supports 40 MHz operation (40 MIPS at 3.3V), and is pin-compatible with the dsPIC33F family.
Architecturally, the PIC24HJ64GP504T-I/PT is built on a Harvard-based modified-RISC core with separate program and data buses, a hardware multiply/divide unit, and DSP-oriented instructions. The integrated DMA engine moves data between peripherals and memory without CPU involvement, freeing cycles for control algorithms. The wide ADC front-end and rich timer/capture/compare peripherals enable high-resolution sampling for motor control and power-conversion loops.
Typical applications include industrial motor control (BLDC, PMSM, and stepper drives), digital power conversion (SMPS, PFC stages, UPS), industrial sensing and data acquisition, automotive body and chassis subsystems, and consumer audio/DSP processing. Designers also deploy it in CAN-based networked embedded systems, robotics, and solar inverter controllers.
When designing with this MCU, ensure that your compiler toolchain targets the pic24-dsp variant (e.g., MPLAB XC16) so that DSP intrinsics and the hardware multiply/divide are enabled. Reserve dedicated analog and digital ground planes and place the 10 uF + 0.1 uF decoupling network close to each VDD/AVDD pin.

Typical Applications
PIC24HJ64GP504T-I/PT is suitable for 6 applications: Industrial BLDC / PMSM Motor Control, Digital Power Conversion (SMPS / PFC / UPS), Industrial Sensing & Data Acquisition, Automotive Body & Chassis Subsystems, Solar Inverter & Renewable Energy Controllers, Consumer Audio & DSP Effects Processing.
Industrial BLDC / PMSM Motor Control
The PIC24HJ64GP504T-I/PT is purpose-built for sensorless and sensored BLDC/PMSM motor drives thanks to its 40 MIPS PIC24H core with hardware multiply/divide. Its three 16-bit timers (pairable into one 32-bit timer) drive center-aligned PWM at up to 40 kHz with sub-microsecond dead-time insertion, while two output compare modules generate complementary PWM pairs for three-phase inverters. The 16-channel 10/12-bit ADC samples phase currents and back-EMF synchronously to the PWM, and the 8-channel DMA streams ADC results without CPU load. CAN 2.0B enables multi-axis networked drives, and the -40C to +85C industrial grade supports factory-floor deployments.
Recommended
Digital Power Conversion (SMPS / PFC / UPS)
For digital switch-mode power supplies, PFC stages, and UPS inverter controllers, the PIC24HJ64GP504T-I/PT delivers DSP-class instructions that accelerate control-loop math (PID, state-space) at 40 MIPS. Its two input capture modules time-stamp zero-current and zero-voltage crossings for cycle-by-cycle current-mode control, while two output compare modules drive PFC and synchronous-rectifier PWMs with programmable dead-time. The integrated CAN peripheral supports paralleled-module communication in telecom rectifier and UPS architectures. With 64 KB Flash it fits single-loop PFC plus full-bridge LLC firmware without external memory.
Recommended
Industrial Sensing & Data Acquisition
Multi-channel industrial sensor nodes and remote telemetry units use the PIC24HJ64GP504T-I/PT for its 16-channel 10/12-bit ADC front-end, 8-channel DMA for background sample streaming, and CAN/RS-485 networking. The Harvard bus executes oversampling and FIR/IIR filter routines without stalling ADC conversions. Industrial-grade -40C to +85C operation supports outdoor and factory-floor deployments, while 8 KB RAM buffers larger sample windows before transmission. The device is also widely used in process-control transmitters and 4-20 mA smart sensor heads.
Recommended
Automotive Body & Chassis Subsystems
In non-safety-critical automotive body and chassis ECUs, the PIC24HJ64GP504T-I/PT controls window lifts, seat positioners, mirror modules, and HVAC flap motors. Its 21 GPIO drive H-bridges and LED arrays directly, while the CAN 2.0B peripheral interfaces to the vehicle bus at 500 kbps. The PIC24H DSP instructions execute PID loops for actuator positioning, and the DMA engine offloads repetitive register updates. Designers also use it in instrument-cluster stepper gauge controllers where deterministic PWM jitter is unacceptable.
Recommended
Solar Inverter & Renewable Energy Controllers
String solar inverters and micro-inverter controllers rely on the PIC24HJ64GP504T-I/PT for MPPT algorithm execution and grid-synchronization loops. Its 40 MIPS performance runs incremental-conductance MPPT at sub-100 ms intervals, while the two output compare modules generate 50/60 Hz line-frequency PWM and high-frequency inverter switching. The ADC samples PV panel voltage, current, and grid voltage simultaneously via DMA, and CAN/Ethernet bridges report telemetry to the cloud gateway. Industrial temperature rating ensures reliable outdoor operation under elevated ambient conditions.
Recommended
Consumer Audio & DSP Effects Processing
The PIC24H DSP extensions make the PIC24HJ64GP504T-I/PT an effective processor for consumer audio effects, equalizers, and class-D amplifier front-ends. The MAC instruction and hardware barrel shifter execute biquad filters and dynamic-range compressors in real time at 48 kHz sample rate. The two I2S-capable SPI peripherals interface to audio DACs and ADCs, while the DMA engine streams audio buffers without CPU intervention. With 64 KB Flash and 8 KB RAM, the device fits reverb/chorus algorithms and multi-band EQ in a single chip.

Design Notes
Place a 10 uF bulk + 0.1 uF ceramic decoupling pair as close as possible to each VDD/AVDD pin pair. Estimated: at 40 MIPS full operation the core draws up to ~70 mA; the 0.1 uF cap suppresses the high-frequency switching noise generated by the internal clock tree and ADC sampling. AVDD must be tied to VDD through a ferrite bead (or 10 ohm resistor) for noise isolation between digital and analog supplies to preserve ADC accuracy.
Route the crystal traces (OSC1/OSC2) as short, symmetric differential pairs guarded by a ground ring. Place the load capacitors within 3 mm of the OSC pins and keep them away from switching signal lines. The MCLR pull-up (typically 10 kohm) should connect to VDD, not AVDD, to prevent analog noise injection through the reset line. Use a dedicated ground pour under the 44-TQFP exposed pad region if present, and stitch with multiple vias to inner ground plane.
Do not exceed 3.6 V on any VDD/AVDD pin - the Flash and I/O structures are not 5 V tolerant and absolute maximum voltage violation will permanently damage the device. Always configure unused I/O pins as outputs driven low (not high-impedance inputs) to minimize current leakage and stray pickup. The PIC24H configuration bits must be set correctly in the source code (FBTICE, IESO, etc.) - missing configuration leaves the part in an undefined oscillator mode that prevents debug connection via ICD.
Estimated: the 44-TQFP (PT) package has a theta_JA of approximately 50 C/W on a standard JEDEC 2-layer test board. At 40 MIPS full-load with all peripherals active, core current is ~70 mA from 3.3 V, giving ~0.23 W dissipation and a ~12 C junction temperature rise above ambient - well within the -40C to +85C industrial rating. For continuous operation at the high-temperature extreme (85 C ambient), ensure the PCB copper area around the TQFP body is at least 1 square inch to keep junction temperature within safe limits.
Compliance Information
RoHS and REACH compliant per Microchip product documentation. Standard PIC24HJ64GP504T-I/PT is not AEC-Q100 qualified; the "E" grade PIC24HJ64GP504-E/ML extends the temperature range to -40C to +125C but is also not AEC-Q100 qualified. For AEC-Q100 automotive designs, use a PIC24HJ or dsPIC33 part specifically marked Q-100 on the datasheet ordering table.
