PIC24HJ64GP502-E/SP - 40 MIPS 16-bit MCU, 64KB Flash, 28-SPDIP | Microchip

A 16-bit microcontroller is a single-chip computer that processes instructions and data on an internal 16-bit data bus, doubling the throughput of 8-bit MCUs while remaining far simpler and lower-power than a 32-bit Cortex-M device. Within the system hierarchy, an MCU sits above the voltage regulator, oscillator, and reset supervisor in a typical embedded design, and below the application-layer firmware that defines the product's behaviour. The PIC24H family specifically targets high-speed, repetitive-control and DSP-adjacent computations, and is pin-compatible with the dsPIC33F family.
Key features of the PIC24HJ64GP502 include a 40 MHz internal clock (with PLL options for higher system clocks), 21 general-purpose I/O pins, an integrated 12-bit ADC with up to 10 channels (depending on package variant), three 16-bit timers that can be paired into a 32-bit timer, two output-capture modules, and a 16-bit parallel master port. The integrated 8-channel DMA controller offloads CPU cycles for peripheral data movement, freeing the core for control-loop math.
The PIC24HJ64GP502 uses a modified Harvard architecture with a 16-bit data path, 24-bit instruction word, and a deterministic interrupt response. The 3.0 V to 3.6 V supply range, nanoWatt power management modes, and on-chip debugging via ICSP make it a strong fit for real-time control applications. The Extended (-E) temperature grade extends operation up to +125C, enabling under-hood industrial and automotive-adjacent deployments.
Typical applications include industrial motor control, sensor signal processing, digital power conversion, LED lighting control, and medical instrumentation. The 28-SPDIP package simplifies breadboarding and rework, which is why this /SP variant is popular for prototype and low-volume through-hole designs.
When designing with the PIC24HJ64GP502-E/SP, observe the maximum 40 MHz Fcy limit and ensure decoupling capacitors are placed near the VDD/VSS pairs. The Extended-grade part is typically more expensive than the Industrial-grade (-I) sibling, so choose -I for commercial/indoor products and -E for harsh-environment or automotive-adjacent designs.
This page synthesizes distributor stock, drop-in same-package alternatives from the PIC24H family (same 28-SPDIP footprint), and design guidance that goes beyond what the manufacturer datasheet alone conveys.

Industrial Motor Control (BLDC/PMSM)
The PIC24HJ64GP502-E/SP drives field-oriented control (FOC) loops for BLDC and PMSM motors in industrial drives. Its 40 MIPS throughput executes Park/Clarke transforms inside a 20 kHz PWM period with comfortable headroom; three 16-bit timers pairable to a 32-bit timer generate complementary PWM with dead-band insertion; the 12-bit ADC samples phase currents via synchronized ADC triggering from PWM edges. The Extended -40 to +125C grade handles under-cabinet ambient swings near inverters, while the 28-SPDIP package eases bring-up on bench prototypes before committing to a QFN spin. The DMA controller offloads ADC-to-RAM transfers, leaving the CPU free for the control law.

Digital Power Conversion (DC-DC / PFC)
The PIC24HJ64GP502-E/SP executes peak-current-mode control loops and digital PFC algorithms for switched-mode power supplies. Its 40 MIPS performance sustains 200 kHz control loops with sample-and-update timing well within one switching period. The integrated 12-bit ADC reads the power-stage current/voltage with hardware-triggered sampling aligned to the PWM edge, eliminating jitter. Two output-compare modules drive primary-side MOSFETs, while DMA moves ADC results into RAM without CPU overhead. The Extended-temperature grade supports -40 to +125C operation in densely-packed telecom and industrial power racks where ambient is elevated.

Sensor Signal Processing and Data Acquisition
The PIC24HJ64GP502-E/SP is well-suited to multi-channel sensor acquisition systems - bridge sensors, RTDs, thermocouples - where 16-bit arithmetic improves filter response over 8-bit MCUs. Its 12-bit ADC with up to 10 channels multiplexes sensor inputs, while 64 KB Flash holds digital-filter firmware (FIR/IIR) and 8 KB RAM holds circular sample buffers. DMA streams conversion data into RAM without CPU intervention, sustaining sample rates above 100 kSPS aggregate. The Extended temperature grade suits outdoor and industrial installations; the 28-SPDIP package simplifies through-hole production for low-volume industrial instrumentation.

LED Lighting and Color-Mixing Controllers
The PIC24HJ64GP502-E/SP drives high-channel-count architectural and stage lighting fixtures where independent PWM dimming per channel is required. Its 40 MIPS handles CIE-1931 color-mixing math, gamma correction, and DMX-512/Art-Net protocol parsing concurrently. Multiple output-compare modules generate high-resolution PWM on each LED channel, while the 12-bit ADC monitors LED forward voltage for thermal-foldback protection. The Extended -40 to +125C range supports enclosed outdoor luminaires where PCB temperature can exceed +85C; the 28-SPDIP package suits retrofit and stage-fixture designs with through-hole manufacturing.

Medical Patient Monitoring Devices
The PIC24HJ64GP502-E/SP meets the requirements of bedside patient monitoring peripherals - pulse oximetry front-ends, infusion pump controllers, and ECG lead-off detection - where deterministic real-time response is mandatory. Its modified-Harvard architecture and single-cycle 16-bit execution deliver predictable interrupt latency under 100 ns, critical for IEC 60601 safety timing. The integrated 12-bit ADC samples bioelectric signals, DMA transfers samples without CPU load, and 64 KB Flash accommodates protocol stacks (USB, Bluetooth HCI via SPI to companion IC). The Extended-temperature range supports emergency-vehicle and operating-room ambient extremes.

Automotive-Grade-Equivalent Industrial Control
The PIC24HJ64GP502-E/SP delivers -40 to +125C operation and CAN connectivity for industrial controllers exposed to under-hood and outdoor-enclosure environments - HVAC actuators, off-highway vehicle subsystems, and agricultural machinery. Its 40 MIPS throughput handles CANopen/J1939 protocol stacks, and the 12-bit ADC reads 0-5 V analog sensor signals via resistor dividers. The integrated DMA sustains high-speed CAN message buffering without dropping frames. The 28-SPDIP package simplifies maintenance and field-replacement in deployed industrial equipment where rework tools are limited.

ڈیزائن نوٹس
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of each VDD/VSS pair and another 10 uF bulk capacitor near the package. The PIC24HJ64GP502's nanoWatt sleep mode draws < 50 uA but brown-out reset (BOR) must be enabled in configuration bits to prevent code execution at unsafe VDD below 3.0 V. AVDD/AVSS require their own dedicated decoupling even if the internal ADC is unused.
Do not confuse the PIC24HJ64GP502 (PIC24H, no DSP) with the pin-compatible dsPIC33FJ64GP202 (dsPIC33F, with DSP). Programming headers must match the device ID - use ICSP with PGD/PGC on RB5/RB6 respectively. The Extended -E grade is typically 10-15% more expensive than the Industrial -I grade; specify -I for commercial/indoor products unless +125C operation is genuinely required.
The 28-SPDIP package has a thermal resistance theta-JA of approximately 70 C/W in still air, dropping to 35 C/W with 100 LFM airflow. At 40 MHz CPU clock with all peripherals active, internal power dissipation is approximately 60 mW, giving a junction-temperature rise of only ~4 C above ambient - well within the +125C Extended limit. No external heatsink is required for typical PIC24HJ64GP502-E/SP designs.
