PIC24HJ256GP210A-I/PT Overview
What is a PIC24H microcontroller? A PIC24H is a 16-bit RISC microcontroller from Microchip's PIC24 family that uses a modified Harvard architecture with 16-bit instructions and 24-bit instructions targeting sixteen data word registers. Within the Microchip taxonomy the PIC24H sits in the 16-bit microcontroller hierarchy: PIC24F (low-power) < PIC24H (high-performance 16-bit) < PIC24E (high-performance 40-70 MIPS) < dsPIC33 (DSP-enabled). It is pin-compatible with the dsPIC33F family, allowing code and PCB reuse when designers migrate to DSP functionality. An embedded DMA engine, multi-channel ADC, and rich peripheral set position the PIC24H for demanding real-time control.
Key features include 256 KB self-programmable Flash with EEPROM emulation in RAM, 16 KB SRAM, an 8-channel DMA controller, two UART modules with IrDA support, two SPI modules, two I2C modules, a 16-channel 12-bit ADC with 500 ksps throughput, and JTAG IEEE 1149.1 boundary-scan compliance. Five 16-bit timer/counter modules, an input capture module, and an output compare/PWM module complete the timer subsystem.
Architecturally the PIC24H uses a single-cycle 16-bit ALU, hardware multiply/divide, and a 24-bit instruction word with 16-bit data paths, achieving up to 40 MIPS at 40 MHz. The internal DMA can transfer data between ADC, UART, SPI, and RAM without waking the CPU, while the integrated 16-channel ADC with dual-sample-and-hold enables simultaneous motor-current and back-EMF measurement.
Typical applications include industrial motor control (BLDC, PMSM, AC induction), high-performance sensor processing, multi-protocol industrial communication bridges, and digital power conversion control loops. The combination of 40 MIPS throughput and DMA offload makes the device well suited for closed-loop control at PWM rates above 100 kHz.
When designing with this MCU, provide adequate bulk capacitance on the 3.3V rail for ADC reference stability, leave JTAG pins accessible for production boundary-scan testing, and ensure external oscillator load capacitors match the crystal manufacturer recommendations for reliable start-up.

Typical Applications
PIC24HJ256GP210A-I/PT is suitable for 6 applications: BLDC / PMSM Motor Control, Industrial Sensor Processing & Data Logger, Multi-Protocol Industrial Communication Bridge, Digital Power Conversion & SMPS Control, Automotive Body & Chassis Modules, Medical Patient Monitoring Devices.
BLDC / PMSM Motor Control
The PIC24HJ256GP210A-I/PT is well-matched to BLDC and PMSM motor drives thanks to 40 MIPS throughput from its 16-bit modified-Harvard core, an 8-channel DMA that offloads ADC reads and PWM updates, and a 16-channel 12-bit ADC at 500 ksps that supports dual-shunt or triple-shunt current sensing. The device drives complementary PWM via output compare modules at switching frequencies above 100 kHz, while the DMA keeps CPU cycles available to run field-oriented control (FOC) loops at sample rates exceeding 20 kHz. Industrial-grade -40C to +85C operation covers most cabinet-mounted drive environments.
Recommended
Industrial Sensor Processing & Data Logger
The PIC24HJ256GP210A-I/PT's combination of 256 KB Flash, 16 KB SRAM, and 8-channel DMA makes it an effective data aggregator for industrial multi-sensor nodes that sample temperature, pressure, flow, and vibration at 1-10 kHz per channel. DMA streams ADC results directly into RAM buffers, freeing the CPU to perform RMS, FFT, or threshold computations and forward them via UART, SPI, or I2C to a host PLC. The wide operating voltage range (3.0V-3.6V) and JTAG boundary-scan support simplify compliance with industrial EMC test plans and end-of-line programming.
Recommended
Multi-Protocol Industrial Communication Bridge
In protocol-bridge applications (Modbus RTU/TCP, CAN, EtherCAT slave, PROFINET), the PIC24HJ256GP210A-I/PT's dual UART with IrDA, dual SPI, dual I2C, and JTAG boundary-scan deliver enough peripheral headroom for dual-master bridges, with 40 MIPS providing the throughput to translate frames at 1 Mbaud without dropping packets. The DMA engine handles burst reads from a high-speed SPI peripheral into RAM, while the CPU runs the protocol state machines. Industrial temperature and 3.3V operation match 24V industrial bus system regulation downstream of an isolated DC-DC.
Recommended
Digital Power Conversion & SMPS Control
The PIC24HJ256GP210A-I/PT suits digital control of SMPS topologies (PFC, LLC, full-bridge, buck/boost) because the 40 MIPS core closes voltage and current loops at 50-200 kHz switching frequencies with margin for adaptive control algorithms. The 12-bit ADC samples current and voltage at sub-microsecond intervals, while the DMA pipelines ADC conversions to a control loop buffer without CPU load. Multiple timer/counter modules generate phase-shifted PWMs for interleaved topologies, and JTAG support eases in-system firmware updates during development cycles.
Recommended
Automotive Body & Chassis Modules
The PIC24HJ256GP210A-I/PT (industrial -40C to +85C) is a cost-effective solution for non-safety automotive body modules like seat controllers, mirror adjusters, and lighting controllers that do not require automotive-grade qualification. Its 40 MIPS supports LIN or CAN communication stacks alongside PWM control of motors and LEDs, while the DMA offloads repetitive peripheral servicing. Designs can migrate upward to AEC-Q100 qualified PIC24HJ variants without PCB changes, since the 100-pin TQFP pinout is shared across the PIC24H/dsPIC33F family.
Recommended
Medical Patient Monitoring Devices
Although not medical-grade certified, the PIC24HJ256GP210A-I/PT is widely used in clinical and wellness devices (blood-pressure monitors, infusion pumps, patient telemetry) where its 40 MIPS enables real-time DSP-style filtering of ECG, pulse-oximetry, or respiration waveforms. The 16-channel 12-bit ADC samples multiple biopotential electrodes simultaneously, while DMA streams waveforms into RAM at high duty cycle. Industrial temperature operation covers bedside environments, and JTAG boundary-scan supports production testing required by IEC 60601-1 quality systems.

Design Notes
The PIC24HJ256GP210A-I/PT requires a stable 3.3V (3.0V-3.6V) supply to all Vdd pins (5, 27, 46, 64, 83, 46) with corresponding ground returns on Vss pins (6, 28, 45, 63, 77, 82). Place 100 nF decoupling capacitors within 3 mm of each Vdd/Vss pair, plus a single 10 uF bulk capacitor near the package. The ADC reference (AVdd/AVss) requires a dedicated low-noise LDO; do not tap AVdd from a digital rail shared with PWM switching loads to avoid coupling noise into conversions.
Keep the analog traces (Port A/E/F analog-capable pins) short and routed away from PWM and switching signals. Provide a single star-ground tie point where AGND and DGND connect, located under the package or at the AVss pin. If using the ADC at 500 ksps, route analog inputs as microstrip over an unbroken ground pour and add a 10 nF RC low-pass filter (1 kOhm + 10 nF) on each analog input to prevent ringing from sensor leads.
Do not omit the external crystal load capacitors on OSC1/OSC2 - Microchip datasheet requires values per crystal manufacturer ESR, typically 15-33 pF. Leave PGEC1/PGED1 (pins 7-8) and PGEC2/PGED2 (pins 9-10) accessible for ICSP programming and JTAG boundary-scan; the MCLR pin must have a 10 kOhm pull-up to Vdd and a 100 nF cap to ground for in-circuit programming. If using DMA, ensure all DMA buffer RAM regions are placed in the 16 KB SRAM range (not in Flash) and are 32-bit aligned to avoid spurious transfers.
For designs using UART at 1+ Mbaud, add a 33 ohm series damping resistor at the UART RX trace near the MCU pin to dampen reflections on cables longer than 50 mm. If using SPI at 10 MHz or above, keep SPI traces matched within 5 mm of each other and route over a continuous ground reference; consider adding 22-33 ohm series resistors at the MCU end to control slew rate. The JTAG clock pin (TCK) requires a 4.7 kOhm pull-down to prevent floating state during reset.
Compliance Information
