PIC24HJ64GP210A-I/PF Overview
A 16-bit microcontroller (MCU) is a microprocessor that processes data and instructions in 16-bit chunks, offering higher performance than 8-bit MCUs while remaining easier to program than 32-bit devices. The PIC24H family occupies the middle tier of Microchip's 16-bit portfolio, sitting between the cost-optimized PIC24F and the digital-signal-controller dsPIC33F. The PIC24HJ64GP210A specifically targets applications that demand deterministic interrupt response and high-throughput DSP-like math but do not require a dedicated DSP engine. It is pin-compatible with the dsPIC33F family, enabling seamless migration when DSP extensions are later needed.
Key features of this device include 64KB (22K x 24 instruction words) of Flash program memory, 8KB RAM, two UART modules, two SPI modules, two I2C modules, a 16-channel 10/12-bit ADC, and four 16-bit timers. The device operates from 3.0V to 3.6V and is rated for the industrial -40C to +85C temperature range. Integrated peripherals include a Parallel Master Port (PMP), Comparators, and a Charge Time Measurement Unit (CTMU) for capacitive touch and precise timing measurements.
Architecturally, the PIC24HJ64GP210A uses a single-cycle instruction fetch with a 2-stage pipeline, dual-bus Harvard memory architecture, and 24-bit wide instruction words. The JTAG and ICD interfaces support real-time in-circuit debugging. The device supports self-programming via Flash program memory, eliminating the need for external boot memory.
Typical applications include industrial motor control (BLDC, PMSM, stepper), sensor signal conditioning, building automation HVAC controllers, Uninterruptible Power Supplies (UPS), power conversion, advanced sensor fusion, and automotive body electronics modules. The 100-pin TQFP package provides ample I/O for multi-axis motion control applications requiring multiple PWM channels and high-resolution ADC sampling.
When designing with this MCU, plan I/O assignments carefully since the 100-pin TQFP exposes most peripherals simultaneously. Use Microchip's MPLAB X IDE with the XC16 compiler and the MPLAB ICD 3 / PICkit 4 programmer for development. Decoupling should follow the datasheet's recommended 0.1uF + 10uF scheme near VDD/AVDD pins with a ground plane to minimize digital switching noise coupling into the analog rail.

Typical Applications
PIC24HJ64GP210A-I/PF is suitable for 6 applications: Industrial Motor Control, Sensor Signal Conditioning and Fusion, Building Automation HVAC Controllers, Uninterruptible Power Supplies (UPS), Power Conversion (Solar Inverter / DC-DC), Industrial Sensor Hubs and IO-Link Masters.
Industrial Motor Control
The PIC24HJ64GP210A-I/PF is purpose-built for BLDC, PMSM, and AC induction motor control where its 40 MIPS throughput executes Field-Oriented Control (FOC) loops in under 25us per iteration. The integrated Motor Control PWM module supports complementary outputs with programmable dead-time insertion, hardware fault blanking, and 16-bit resolution for smooth commutation at low speeds. With 16 ADC channels sampled at 500 ksps, the device reads three-phase currents, DC bus voltage, and position feedback simultaneously. The 64KB Flash holds FOC lookup tables, speed PI controllers, and CANopen or Modbus communication stacks without external memory. Compared with ARM Cortex-M0 alternatives, the PIC24HJ64GP210A's deterministic interrupt latency and single-cycle bit manipulation simplify real-time control firmware development. Pair with the MCP8024 BLDC gate driver for a complete 3-phase motor drive solution.
Recommended
Sensor Signal Conditioning and Fusion
The PIC24HJ64GP210A-I/PF's 10/12-bit ADC with up to 16 channels handles multi-axis sensor arrays in industrial instrumentation. Its CTMU (Charge Time Measurement Unit) enables precise capacitance measurement for capacitive touch sensors and humidity probes, with sub-pF resolution at 1ms sample times. The 40 MIPS core processes Kalman filter loops and digital sensor fusion (IMU + encoder + tachometer) in real time. With two SPI and two I2C ports, the MCU reads digital accelerometers, gyroscopes, and pressure sensors concurrently while driving UART diagnostics. The 8KB RAM holds sufficient buffer space for 1kHz sensor sampling across multiple channels. The PIC24H's deterministic interrupt architecture guarantees that the control loop completes within a fixed time, critical for safety-rated sensor systems where unpredictable timing would violate functional safety budgets.
Recommended
Building Automation HVAC Controllers
HVAC controller boards require multiple analog sensor inputs (temperature, humidity, pressure, CO2), several PWM outputs for damper and valve actuators, and reliable serial communication to building management systems. The PIC24HJ64GP210A-I/PF provides 16 ADC channels and four 16-bit timers, ample for multi-zone climate control. Its 3.3V operation aligns with modern low-power building automation designs, while the 100-pin TQFP exposes enough GPIO for keypad, LCD, and relay control without expanders. The 64KB Flash supports BACnet or Modbus protocol stacks plus scheduling firmware, while 8KB RAM holds HVAC state machines. With the industrial -40C to +85C temperature grade, the device operates reliably in unconditioned equipment closets and rooftop units. Compared with 8-bit PIC16 alternatives, the PIC24H's 16-bit core runs 3-5x faster, enabling smoother PI control loops and more responsive user interfaces.
Recommended
Uninterruptible Power Supplies (UPS)
In a UPS, the PIC24HJ64GP210A-I/PF samples the AC line and battery voltage at 8-16 kHz, runs RMS calculations, and generates inverter PWM with sub-1% THD. Its four 16-bit timers produce the sine-wave PWM at 20 kHz carrier frequency while the ADC acquires feedback simultaneously with hardware-triggered conversion. The 64KB Flash holds inverter control algorithms, battery charge profiles (sealed lead-acid, LiFePO4), and communication firmware for USB HID or RS-232 monitoring. The 100-pin TQFP package provides sufficient I/O for relay control, status LEDs, and an alphanumeric LCD interface. The 40 MIPS throughput is enough to implement advanced digital control such as repetitive control for harmonic rejection and adaptive dead-time compensation. The device's industrial temperature grade ensures reliable operation near transformers and battery cabinets.
Recommended
Power Conversion (Solar Inverter / DC-DC)
The PIC24HJ64GP210A-I/PF drives grid-tied solar microinverters, MPPT charge controllers, and bidirectional DC-DC converters. Its high-speed 10/12-bit ADC samples PV panel voltage and current for perturb-and-observe or incremental conductance MPPT algorithms at 100 Hz loop rates. The Motor Control PWM module can be repurposed as a 16-bit PWM generator for MOSFET/IGBT gate drive signals at 50-200 kHz switching frequencies. With 64KB Flash and 8KB RAM, the MCU runs MPPT, anti-islanding, and grid-synchronization logic in software without external DSP chips. The 100-pin TQFP package supports the multiple isolated gate-driver signals, current shunts, and AC line voltage feedback channels needed in a complete inverter design. Compared with discrete analog controllers, the PIC24H's software flexibility accelerates regulatory compliance (UL1741, IEEE1547) through firmware revisions rather than hardware respins.
Recommended
Industrial Sensor Hubs and IO-Link Masters
The PIC24HJ64GP210A-I/PF serves as a multi-protocol sensor hub in industrial IO-Link masters, aggregating data from 4-8 IO-Link slaves and forwarding to a PLC via PROFINET or EtherNet/IP. Its two UART channels interface with IO-Link stack ICs (e.g., MAX14821) for each port, while SPI drives the industrial Ethernet controller. The 40 MIPS core runs IO-Link v1.1 protocol stacks with cycle times under 5ms, and 64KB Flash accommodates multiple port handlers plus diagnostic firmware. The device's CTMU measures sensor cable resistance and detects open/short conditions per IO-Link standard. With 85 GPIO exposed via the 100-pin TQFP, the design needs no external I/O expanders, reducing BOM cost. The PIC24H's deterministic interrupt latency ensures IO-Link cycle timing is met under worst-case loading, critical for industrial deterministic network requirements.

Design Notes
Estimated: Decoupling is critical for MCU stability. Place one 0.1uF X7R ceramic capacitor on every VDD/AVDD pin pair, located within 3 mm of the pin and routed with wide, short traces. Add a single 10uF bulk capacitor per VDD plane region near the MCU. According to the Microchip datasheet, AVDD noise above 50 mVpp degrades ADC accuracy by 1-2 LSBs, so use a ferrite bead or pi-filter between VDD and AVDD when the digital switching load is heavy.
At 40 MIPS full-load operation, the PIC24HJ64GP210A-I/PF dissipates approximately 0.5 W (estimated, VDD=3.3V, I_core~150 mA). The 100-pin TQFP package has a theta_JA of approximately 35-45 C/W on a 4-layer JEDEC test board, yielding a junction-to-ambient rise of 18-22 C above ambient. At industrial temperatures this is well within limits, but for enclosed designs above 70 C ambient, add thermal copper pours and vias under the exposed thermal pad region. Extended temp grade (E suffix) variants should be specified for environments exceeding 85 C.
Two common pitfalls in PIC24HJ64GP210A designs: (1) Failing to configure the JTAG/ICSP pins as analog or digital I/O after programming - the MCLR, PGC, PGD pins default to programming mode and must be reassigned in configuration bits for normal application use. (2) Stack overflow in deeply nested interrupts - the PIC24H has a software-controlled stack pointer with no hardware overflow detection. Use MPLAB XC16's stack-usage analysis tools and reserve at least 256 bytes of stack headroom for safe interrupt nesting. Always enable the watchdog timer with a 1-2 second timeout for unattended industrial deployments.
Route the 16 MHz primary oscillator traces as short and symmetric as possible, with the load capacitors placed within 2 mm of the OSC1/OSC2 pins. Keep crystal traces away from high-current switching traces (PWM, motor drivers) and away from digital signals to avoid coupling-induced frequency jitter. For noise-sensitive analog designs, use a ground guard ring around the crystal area. Place the MCLR pull-up resistor (typically 10k) close to the MCLR pin and add a 100 nF capacitor for noise immunity. The 100-pin TQFP package has fine 0.5 mm pitch traces, so use 0.2 mm trace widths with 0.2 mm spacing on outer layers.
Compliance Information
