PIC24HJ256GP610AT-I/PF Descripción general
A 16-bit microcontroller (MCU) is a single-chip computer that combines a 16-bit CPU core, program memory (Flash/ROM), working memory (RAM), and a rich set of on-chip peripherals. The PIC24H sits in Microchip's mid-range 16-bit portfolio, positioned above the 8-bit PIC16/PIC18 families for higher-throughput signal-processing and control applications. The PIC24H family is software- and pin-compatible with the dsPIC33F DSC family, allowing code and PCB reuse when motor-control or DSP features are later required.
Key differentiating features of the PIC24HJ256GP610AT-I/PF include 256 KB (85.5K x 24) Flash, 16 KB SRAM, a 16-channel 10-bit ADC capable of 1.1 Msps, two UART modules, two SPI modules, two I2C modules, an Enhanced CAN 2.0B module, and two 16-bit timers plus two 32-bit timers. The 40 MIPS core at 3.3V provides ample headroom for closed-loop control algorithms. The 100-TQFP footprint exposes up to 85 I/O pins, supporting parallel bus interfaces and dual analog front-end channels simultaneously.
Architecturally, the PIC24HJ256GP610A device employs a 16-bit data path with 24-bit instruction words, a 7-stage pipeline, hardware multiply/divide, and a flexible interrupt controller with 5-cycle latency. The on-chip DMA controller (8-channel) offloads data movement between peripherals and RAM, freeing the CPU for control loops. The device operates from 3.0V to 3.6V and supports industrial-grade -40C to +85C ambient temperatures.
Typical applications include industrial motor control (BLDC/PMSM FOC), CAN-connected automotive body and chassis ECUs, digital power conversion (SMPS control loops), medical instrumentation signal processing, multi-loop process control, and embedded graphics/HMI controllers. The combination of CAN, ADC, PWM, and 40 MIPS throughput makes it a strong fit for real-time industrial networking nodes.
When designing with this part, reserve a dedicated 3.3V LDO rail (such as MCP1700) and follow Microchip's recommended 100 nF + 10 uF decoupling arrangement. Configure the FRC + PLL block to deliver 40 MIPS from an 8 MHz crystal via the FPLLIDIV:FPLLODIV chain, and ensure the Vcap pin is tied to a 10 uF low-ESR capacitor. Industrial designers should also provision the ICD/PGD/PGC pins for in-circuit programming access.

Aplicaciones típicas
PIC24HJ256GP610AT-I/PF es adecuado para 6 aplicacións: Industrial CAN-Connected Motor Control, Digital Power Supply SMPS Control, Automotive Body and Chassis ECU, Medical Instrumentation Signal Processing, Embedded HMI with TFT Display Controller, Process Control and Industrial Sensor Hub.
Industrial CAN-Connected Motor Control
The PIC24HJ256GP610AT-I/PF's 40 MIPS throughput and integrated ECAN 2.0B controller make it a strong fit for industrial CAN-connected motor-drive nodes such as conveyor controllers and BLDC/PMSM servo amplifiers. With 16 KB SRAM and 256 KB Flash, it can host a full CANopen stack alongside a sensorless or Hall-sensor trapezoidal commutation loop. Designers pair the MCU with a 3.3V CAN transceiver like MCP2551, drive 6 PWM channels through the ECAN-driven control loop, and use the dual 16-bit timers for tachometer input capture. The 100-TQFP footprint provides 85 I/O pins, leaving ample headroom for incremental encoder, Hall sensors, and analog feedback channels. Compared to 8-bit PIC18 alternatives, the 16-bit core delivers 10x faster interrupt latency (5-cycle deterministic response), reducing PWM jitter to <100 ns and improving commutation smoothness under dynamic load.
Recomendado
Digital Power Supply SMPS Control
The PIC24HJ256GP610AT-I/PF is widely used as the control core in digitally controlled switch-mode power supplies (SMPS), where its 40 MIPS throughput drives state-of-the-art digital control loops at 100 kHz+ switching frequencies. The 10-bit 1.1 Msps ADC samples output voltage and current at high resolution, while the PWM/Output Compare modules deliver up to 6 high-resolution PWM channels with 7.5 ns dead-band control for half-bridge drivers. Designers implement digital peak current mode control, LLC resonant control, or PFC control loops in firmware, using the on-chip DMA to move ADC samples without CPU intervention. Compared to discrete analog UC3842 controllers, the PIC24HJ256GP610A enables software-flexible compensation, telemetry, and remote monitoring over CAN or UART. For high-voltage systems, the 3.3V core is isolated from the high-voltage primary via a digital isolator (Si8261 or ADuM1410).
Recomendado
Automotive Body and Chassis ECU
Although the PIC24HJ256GP610AT-I/PF is industrial-grade (-40C to +85C), it is commonly designed into automotive body-electronics prototypes and aftermarket ECU modules where AEC-Q100 qualification is not strictly required. The ECAN 2.0B module interfaces directly with automotive CAN bus networks (500 kbps body CAN, 125 kbps chassis CAN), while the dual UART supports LIN-bus slave communication through an external LIN transceiver. The 256 KB Flash holds a full CAN bootloader plus application firmware with A/B partition redundancy. The 100-TQFP package exposes up to 85 I/O pins, supporting load drivers, switch inputs, and analog sensor conditioning. Compared to 8-bit PIC16F alternatives, the 16-bit core executes complex CAN diagnostics (UDS, OBD-II PIDs) and PID-control loops for HVAC, lighting, or seat control within the real-time CAN cycle.
Recomendado
Medical Instrumentation Signal Processing
The PIC24HJ256GP610AT-I/PF's 40 MIPS performance and 10-bit 1.1 Msps ADC make it a suitable MCU for portable medical instrumentation such as pulse oximeters, blood-pressure monitors, and digital stethoscope front-ends. The 16-bit DSP-friendly instruction set accelerates FIR/IIR filter pipelines for heart-rate extraction and SpO2 computation (Beer-Lambert law). The dual UART enables Bluetooth module connection for wireless telemetry to a host tablet/phone, while the 16 KB SRAM holds multiple seconds of waveform buffer plus filter state. Compared to lower-end 8-bit MCUs, the 16-bit core processes FFT or wavelet analysis in firmware with deterministic 25 ns instruction cycles, critical for real-time bio-signal visualisation. Designers add an external 24-bit ADC (such as MCP3564) for high-resolution acquisition, but the on-chip 10-bit ADC handles housekeeping and battery monitoring.
Recomendado
Embedded HMI with TFT Display Controller
The PIC24HJ256GP610AT-I/PF's 256 KB Flash and 85 I/O pins make it a strong host controller for embedded human-machine interface (HMI) panels with small TFT displays (3.5 to 5 inches, QVGA/WQVGA). The External Bus Interface (EBI) module maps external SRAM/Flash into the data space, allowing off-chip framebuffer memory for graphics rendering. Designers use the SPI or parallel PMP (Parallel Master Port) to drive TFT controllers such as HX8347 or ILI9488. The 40 MIPS throughput drives button scanning, LED driving, and refresh loops at 30+ FPS without DMA contention. Compared to PIC32MM or STM32F0 alternatives, the PIC24HJ256GP610A is more cost-effective at low-mid HMI complexity, especially when the firmware stack does not require an RTOS. The dual UART provides Modbus or RS-485 connectivity to host PLCs.
Recomendado
Process Control and Industrial Sensor Hub
The PIC24HJ256GP610AT-I/PF is widely deployed in industrial process-control sensor hubs, where it aggregates analog/digital inputs from 4-20 mA loops, thermocouples, RTDs, and digital sensors, then transmits readings via RS-485 Modbus or CANopen. The 10-bit ADC with up to 32 channels handles multi-channel sensor conditioning via external multiplexers, while the on-chip DMA streams ADC samples into RAM without CPU intervention. The 16 KB SRAM supports circular buffers for averaging, FFT, and outlier rejection. Designers implement PID loops in firmware for heating/cooling element control using Output Compare PWM channels. Compared to 8-bit PIC18F alternatives, the 16-bit core executes multi-loop PID control with 5-cycle deterministic interrupt response, reducing process overshoot. The 100-TQFP package supports PCB integration with isolation barriers (Si8261) for high-voltage analog input protection.

Notas de diseño
Provide a dedicated 3.3V LDO (such as MCP1700-3302E or equivalent) for VDD/AVDD. Decouple every VDD pin with 100 nF ceramic and one 10 uF bulk near the package. Place a single 10 uF low-ESR ceramic (X7R) capacitor on the VCAP pin to stabilise the internal 2.5V core regulator; insufficient capacitance causes Flash programming failures and erratic DMA behaviour. AVSS and VSS must be tied to a common ground plane with single-point star routing.
Route the 100-TQFP (14x14) footprint with 0.5 mm pitch traces and 0.25 mm via-in-pad recommended for the inner-row signal pins to escape the dense perimeter. Keep crystal traces (OSC1/OSC2) short (< 5 mm) and shield with a guard ground to minimise jitter. Provide a 4-layer PCB stack-up with one continuous ground plane beneath the MCU to control EMI from the 40 MIPS switching transitions.
Do not use the PIC24HJ256GP610AT-I/PF for AEC-Q100 automotive designs - this part is industrial-grade only; choose dsPIC33FJ256GP610A-E/PF or PIC24HJ256GP610A-E/PF for -40C to +125C. Always pull MCLR high through a 10 kohm resistor to VDD with a 100 nF capacitor; leaving MCLR floating causes spurious resets during in-circuit debug. Configure FPLLIDIV:FPLLODIV:FPLLMUL chain for 40 MIPS and avoid exceeding 8 MHz crystal load capacitance spec.
When driving high-speed signals off-board (CAN, SPI), add source-series 22-33 ohm resistors to dampen reflections. The ECAN bus requires twisted-pair cable with 120 ohm termination at each end; place the 120 ohm resistors within 5 mm of the MCP2551 CANH/CANL pins. For PWM output to gate drivers, place 10 ohm gate resistors close to the IC pin to suppress ringing caused by MOSFET gate-drain capacitance.
Información de cumplimiento
