PIC24HJ256GP210-I/PT Overview
A 16-bit microcontroller (MCU) is a single-chip computer that executes instructions on 16-bit-wide data paths, sitting in the hierarchy between 8-bit MCUs (such as the PIC16/PIC18 families) and 32-bit MCUs (such as the PIC32MX or ARM Cortex-M devices). Within Microchip's taxonomy the PIC24H family is the highest-performance 16-bit line before the dsPIC33F DSC family, sharing pin compatibility with dsPIC33F and offering seamless migration paths to/from PIC24F and dsPIC30F. These MCUs target embedded control applications that demand deterministic interrupt response, DSP-class math, and abundant I/O.
Key features of the PIC24HJ256GP210-I/PT include 256 KB self-programmable flash (85.5K x 24 words) with EEPROM emulation, 16 KB SRAM, a 16-channel hardware DMA controller that offloads data movement from the CPU, an Enhanced CAN 2.0B module for automotive and industrial networking, four 16-bit timers, nine 16-bit Input Capture and Output Compare/PWM channels, a Real-Time Clock/Calendar with on-chip low-power 32 kHz crystal oscillator, and a 10-bit 1 MSPS ADC alongside the 12-bit 500 ksps ADC. The Industrial temperature grade (-40 °C to +85 °C) and TQFP-100 footprint make it broadly applicable across factory automation, motor control, and medical instrumentation.
Architecturally the PIC24HJ256GP210 uses a 24-bit instruction word with 16-bit data paths, a 7-stage pipeline, hardware multiply/divide (17-bit x 17-bit single-cycle MAC), and a deterministic interrupt latency of 5 cycles. Its peripheral set is mapped onto a peripheral pin-select (PPS) matrix that allows most digital functions to be remapped to a wide range of I/O pins, simplifying PCB routing. The 16-bit Parallel Master Port and Enhanced CAN module position this device for applications that previously required external logic or a secondary MCU.
Typical applications include industrial motor control (BLDC, PMSM, AC induction), CAN-based automotive body and chassis nodes, graphic LCD or OLED user-interface controllers, multi-channel data-acquisition systems, and digital signal conditioning. It is pin-compatible with the entire PIC24HJXXXGPX06/X08/X10 family and with the dsPIC33FJXXXGPX06/X08/X10 DSC devices, which simplifies firmware upgrades when the application outgrows a pure control MCU and requires on-chip DSP.
When designing with the PIC24HJ256GP210-I/PT, plan decoupling with at least one 0.1 µF ceramic capacitor per Vdd/Vss pair and a single bulk 10 µF tantalum or ceramic near the regulator output. The device can be programmed and debugged in-circuit via Microchip's ICD 3, REAL ICE, or PICkit 3 programmers using the standard 2-wire PGECx/PGEDx interface.

Typical Applications
PIC24HJ256GP210-I/PT is suitable for 7 applications: Industrial Motor Control (BLDC / PMSM), Automotive CAN Body/Chassis Modules, Multi-Channel Data Acquisition Systems, Graphical LCD / OLED HMI Controllers, Industrial Ethernet / Serial Gateways, Medical Patient Monitoring Peripherals, Sensor Hub / IoT Edge Node.
Industrial Motor Control (BLDC / PMSM)
The PIC24HJ256GP210-I/PT's 40 MIPS CPU (60 MIPS with PLL) provides enough headroom for field-oriented control (FOC) loops on 3-phase BLDC and PMSM motors, while the 6 PWM output-compare channels and 9 input-capture modules handle quadrature encoder feedback with sub-microsecond resolution. The 12-bit 500 ksps ADC samples phase currents synchronously to the PWM center, and the 16-channel DMA offloads sensor data from the CPU, leaving cycles for housekeeping and CAN comms. Pair the MCU with a 3-phase gate driver such as the Microchip MCP8024 or a discrete bootstrap FET driver for a complete 24 V sensorless FOC drive.
Recommended
Automotive CAN Body/Chassis Modules
The PIC24HJ256GP210-I/PT integrates an Enhanced CAN 2.0B module and a 100-pin TQFP footprint, making it well suited for automotive body-control modules that orchestrate door locks, lighting, and HVAC actuators over a 500 kbit/s CAN bus. With 256 KB flash and 16 KB SRAM, firmware can comfortably embed J1939 or CANopen stacks plus diagnostic UDS services. The Industrial -40 to +85 °C temperature range covers most cabin and under-hood-near applications, and the PIC24HJ256GP210A-E/PT variant extends to +125 °C for harsher placements. Pair the MCU with a CAN transceiver such as the MCP2551 or TJA1050 and an automotive-grade LDO like the MCP1790.
Recommended
Multi-Channel Data Acquisition Systems
With up to 32 channels of 12-bit 500 ksps ADC, the PIC24HJ256GP210-I/PT serves as the front-end controller for multi-channel data-acquisition systems used in industrial process monitoring and medical instrumentation. The 16-channel DMA streams conversion results directly to SRAM, freeing the CPU to perform averaging, threshold detection, or FFT-style processing at up to 40 MIPS. The on-chip 10-bit 1 MSPS auxiliary ADC can monitor supply rails and die temperature concurrently with the precision ADC, eliminating the need for external analog supervision. Pair with an external 16/24-bit sigma-delta ADC such as the MCP3911 when higher resolution is required for weigh-scale or strain-gauge front ends.
Recommended
Graphical LCD / OLED HMI Controllers
The PIC24HJ256GP210-I/PT's 16-bit Parallel Master Port (PMP) drives 8080/6080-mode graphical LCDs and OLED panels up to QVGA resolution at 30+ FPS, while the 256 KB flash stores full framebuffer routines plus font tables. The 16 KB on-chip SRAM and 85 remappable I/O pins allow the PMP data bus plus touch-screen SPI/I²C peripherals to coexist without bus contention. The on-chip DMA channels accelerate pixel block transfers to the display, leaving CPU cycles for USB or UART host interfaces. Pair with a 2.8-inch TFT (such as the Microchip AC320005-4) and a resistive touch controller such as the AR1021.
Recommended
Industrial Ethernet / Serial Gateways
At 40 MIPS the PIC24HJ256GP210-I/PT can run Modbus RTU/TCP gateways or PROFINET-DP slave stacks without offloading to a higher-tier processor. Its dual UART, dual SPI, and I²C peripherals provide enough bridges for RS-485, RS-232, and sensor-bus aggregation, while the integrated CAN 2.0B controller serves as a third industrial network. Use the 32 kHz SOSC with the on-chip RTCC for timestamping logs and scheduled wake-up. Pair with the ENC28J60 Ethernet controller plus a TLK110 PHY, or migrate to the dsPIC33E family when deterministic Ethernet (EtherCAT) is required.
Recommended
Medical Patient Monitoring Peripherals
The PIC24HJ256GP210-I/PT's deterministic 5-cycle interrupt latency, on-chip DMA, and 12-bit ADC support multi-parameter medical peripherals such as pulse oximetry front ends, infusion-pump keypads, and small-form-factor patient monitors. The 256 KB flash accommodates USB device class stacks (CDC, HID, vendor) for tethered bedside monitors, while the Industrial temperature grade satisfies the operating environment of clinical carts. Pair with an external 16/24-bit sigma-delta ADC such as the MCP3911 for ECG front ends and a Bluetooth module (RN4870) for wireless tethering.
Recommended
Sensor Hub / IoT Edge Node
The PIC24HJ256GP210-I/PT aggregates I²C and SPI sensors, performs local thresholding or averaging at 40 MIPS, then publishes results over CAN, UART, or a Wi-Fi/BLE module. The 16-channel DMA and PMP make it ideal for camera or imaging-sensor pre-processing, while the Industrial temperature range suits outdoor enclosures and factory floors. Pair with an ESP32 or RN4870 for cloud connectivity and a Microchip MCP9808 temperature sensor for environmental calibration.

Design Notes
Decouple each Vdd/Vss pair with a 0.1 µF ceramic capacitor placed within 2 mm of the pin, and place a single 10 µF bulk ceramic or tantalum near the regulator output. The PIC24HJ256GP210 has multiple Vdd/Vss pairs (digital core, digital I/O, and analog AVDD/AVSS); all must be decoupled even if some appear unused. AVDD should be tied to Vdd through a small ferrite bead (600 ohm @ 100 MHz) when the ADC is used, to reject digital switching noise on the analog rail.
The TQFP-100 package has a theta_JA of approximately 41 °C/W on a 4-layer JEDEC test PCB, rising to ~60 °C/W on a 2-layer board. Estimated: at full 40 MIPS CPU throughput with all peripherals active, the core draws ~80 mA from Vdd, dissipating 264 mW; junction rise over a 25 °C ambient is ~11 °C on 4-layer PCB, ~16 °C on 2-layer. This is well inside the -40 to +85 °C industrial envelope, so no heatsink is required - only sensible PCB copper area underneath the exposed die pad region.
Do not leave the MCLR pin floating - it must be tied to Vdd through a 10 kohm pull-up (or to a supervisor) for reliable operation. The PGECx/PGEDx programming pins should have no series resistance on the ICSP header path or ICD 3/PICkit 4 will fail to talk to the MCU. If your firmware uses the on-chip RTCC with the secondary 32 kHz crystal, the SOSCI/SOSCO traces must be short (<5 mm) and guarded by a ground ring to prevent injection from the high-speed CPU oscillator.
Route the 32 kHz SOSC crystal traces symmetrically, both within 2 mm of the SOSCI/SOSCO pins and surrounded by ground pour on both layers. The high-speed 8 MHz primary crystal (or external clock) traces should be at most 10 mm long and avoid running parallel to analog ADC traces. Place the AVDD decoupling capacitors adjacent to their analog pins, not stacked on top of the digital decoupling. Use Microchip's MPLAB X IDE with the 'Graphical Pin Selector' utility to confirm peripheral pin select (PPS) remapping before committing the layout.
