PIC24HJ256GP210AT-I/PF Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (SRAM), and a rich set of peripherals on a single silicon die. The PIC24HJ256GP210AT-I/PF belongs to the PIC24HJ 16-bit MCU family that occupies the middle of Microchip's 16-bit portfolio (F >> H >> EP), bridging 8-bit PIC16/PIC18 designs and the dsPIC33F digital signal controllers. Its 16-bit modified-Harvard architecture with 24-bit instructions targets deterministic real-time control rather than integer-crunching DSP workloads.
Key differentiating features include a 40 MHz maximum clock frequency producing 40 MIPS of sustained throughput, an enhanced 16-bit timer/capture/compare module set, dual UART/SPI/I2C peripherals, an internal 7.37 MHz Fast RC oscillator with PLL, and 85 GPIO pins arranged across multiple I/O ports. The device operates from 3.0-3.6 V, supports an industrial -40C to +85C temperature range (I-grade), and includes JTAG boundary-scan alongside Microchip's ICSP programming interface for in-circuit debug.
Architecturally, the PIC24HJ256GP210A employs a 5-stage pipeline, a 16 x 16-bit working register array, and a DMA engine that can shuttle data between peripherals and RAM without CPU intervention. The 'A' silicon revision (PIC24HJ256GP210A) extends peripheral timing and electrical performance over the original PIC24HJ256GP210, while pin-for-pin compatibility with the dsPIC33F family allows migration to DSP capability if FFT/FIR math becomes a requirement.
Typical applications include industrial motor control (BLDC/PMSM FOC), multi-loop PID process control, building automation HVAC controllers, PLC expansion modules, power-conversion digital controllers (DC/DC, PFC), and graph display driver MCUs for HMI panels. The 100-pin TQFP footprint gives designers 85 GPIO plus analog channels for keypad, LCD, motor-driver, and communication interfaces simultaneously.
When designing with this device, plan the PLL configuration and oscillator start-up delay carefully because the internal FRC + PLL loop must settle before the regulator can release the system. A 1 mF bulk + 100 nF decoupling pair at each VDD/VSS pair is essential given the 40 MIPS switching activity of this PIC24HJ256GP210A industrial MCU.

Typical Applications
PIC24HJ256GP210AT-I/PF is suitable for 6 applications: Industrial BLDC / PMSM Motor Control, Building Automation HVAC Controllers, Power Conversion Digital Controllers (DC/DC, PFC), PLC Expansion and I/O Modules, HMI / Graphical Display Controllers, Medical Monitoring Devices.
Industrial BLDC / PMSM Motor Control
The PIC24HJ256GP210AT-I/PF drives 40 MIPS 16-bit control loops for sensorless and sensored BLDC/PMSM motors. Its 5 16-bit timers with PWM output modes support complementary 3-phase PWM at 20 kHz switching frequency, while the 1.1 Msps 10-bit ADC samples back-EMF and phase currents at the required 10 kHz control rate. The 256 KB Flash hosts field-oriented control (FOC) and sensorless observer libraries, while 32 KB auxiliary Flash stores tuning parameters. Designers pair the part with Microchip MCP8026 3-phase gate drivers and use the 85 GPIO to drive HALL sensors, fault flags, and CAN communication simultaneously. The -40 C to +85 C industrial range supports factory floor deployment.
Recommended
Building Automation HVAC Controllers
The PIC24HJ256GP210AT-I/PF is ideal for commercial HVAC control boards requiring simultaneous temperature, humidity, and damper position loops. The 85 GPIO plus dual UART/SPI/I2C peripherals support multiple RS-485 Modbus RTU channels, BACnet MS/TP links, and I2C sensor arrays without external bus expanders. The 40 MIPS throughput executes 8 multi-stage PID controllers at 100 Hz loop rates while leaving CPU headroom for Modbus stack processing and LCD HMI updates. Industrial -40 C to +85 C operation covers unconditioned plant-room deployment, and 256 KB Flash accommodates full BACnet/Modbus protocol stacks plus application firmware.
Recommended
Power Conversion Digital Controllers (DC/DC, PFC)
The PIC24HJ256GP210AT-I/PF serves as the digital control core for telecom-grade isolated DC/DC converters and PFC front ends. The 5 16-bit timers generate phase-shifted full-bridge PWM at up to 1 MHz resolution while the 1.1 Msps ADC samples output voltage and current at 100 kHz loop rates. The 8-channel DMA engine offloads waveform sampling without CPU intervention, leaving the 40 MIPS core free to execute digital average current-mode control (ACMC) firmware. Industrial temperature range and 256 KB Flash support full-state feedback plus telemetry logging in modular PSU designs.
Recommended
PLC Expansion and I/O Modules
The PIC24HJ256GP210AT-I/PF fits industrial PLC digital and analog I/O expansion modules with its 85 GPIO plus 16 ADC channels. The DMA-driven UART ports implement Modbus RTU slave communication, while SPI peripherals drive high-speed shift-register input modules with 1 ms scan times. Industrial temperature operation and 3.0-3.6 V VDD tolerate 24 V field wiring through external opto-isolators. The 256 KB Flash hosts full IEC 61131-3 function-block interpreters or ladder-logic runtimes for soft-PLC implementations.
Recommended
HMI / Graphical Display Controllers
The PIC24HJ256GP210AT-I/PF drives small TFT/STN graphical LCD panels in industrial HMI terminals where deterministic loop times are critical. Its 85 GPIO plus 8-bit PMP bit-executeable port interface TFT STN-compatible modules up to QVGA resolution without external display controllers. The 16 KB SRAM accommodates 320x240 frame buffers in 4-bit color depth while the 40 MIPS CPU executes touch-screen processing, keypad scanning, and Modbus RTU slave tasks concurrently. Industrial -40 C to +85 C operation tolerates factory cabinet ambient temperatures.
Recommended
Medical Monitoring Devices
The PIC24HJ256GP210AT-I/PF serves low-to-mid-tier patient monitoring equipment where deterministic real-time response is more important than DSP throughput. The 40 MIPS core runs ECG/EEG acquisition front-ends with simultaneous lead-off detection and pacing the 10-bit ADC at 1 kHz sample rates per channel. The 16 ADC channels scan multiple physiological signals in round-robin fashion while DMA transfers samples to RAM without CPU intervention. Although not AEC-Q100 qualified (Microchip parts typically are not unless specified), the industrial temperature range and long-term Microchip supply continuity make it attractive for non-life-support medical peripherals.

Design Notes
Place one 100 nF ceramic decoupling capacitor as close as possible to each of the 5 VDD/VSS pin pairs (pins 2/3, 21/22, 39/40, 53/54, 67/68, 79/80). Add a single 10 uF bulk capacitor near the chip to stabilize the 3.3 V rail during ADC sampling transients. The PIC24HJ256GP210A core draws approximately 60 mA at 40 MIPS with all peripherals active; undersized decoupling leads to VDD droop that corrupts ADC conversions and may trigger brown-out resets.
The MCLR pin (pin 95) requires a 10-100 kohm pull-up to VDD for normal operation; leaving it floating prevents the regulator from releasing the system. The MCLR voltage rise is reduced to a hardware-mandated rise rate by the on-chip MCLR filter; too large a pull-up resistor (over 100 kohm) prevents reliable exit from reset. Also ensure the JTAG TMS line has a weak pull-up at power-up if JTAG boundary-scan is unused.
Estimated: at 40 MHz operation with all peripherals enabled, the PIC24HJ256GP210AT-I/PF dissipates approximately 0.5-0.7 W in a 100-pin TQFP-14x14 package (input voltage 3.3 V, ambient 25 C). The I/PF thermal pad in 14x14 mm TQFP has theta_JA near 35 C/W typical, yielding junction temperature rise near 18-25 C above ambient. For sealed enclosures above 60 C ambient, derate clock frequency or add a top-side copper heatsink pour to keep Tj below 125 C.
Keep the 40 MHz crystal traces (OSC1/OSC2, pins 4-5) under 10 mm in length and surround them with a ground pour to minimize EMI. Route analog ADC inputs (RA0-RA11, RB0-RB3) away from digital switching traces; place the AVR_AVDD filter capacitor within 5 mm of the analog AVDD pin if exposed. The PIC24HJ256GP210A datasheet (DS70087G) section 22 shows reference PCB layout for noise-critical ADC sampling at 1.1 Msps.
