PIC24HJ256GP610T-I/PT 概要
A 16-bit microcontroller (MCU) is an integrated circuit that combines a CPU, program memory (typically Flash), data memory (RAM), and on-chip peripherals (timers, ADC, communication blocks) into a single silicon die. PIC24H MCUs use a modified Harvard architecture with a 16-bit data path and 24-bit instruction word, balancing deterministic interrupt response with high computational throughput suitable for real-time control, digital signal processing pre-processing, and complex communication stacks. Compared with 8-bit MCUs, PIC24H parts deliver higher code density, larger addressable memory, and richer peripheral integration while retaining the same peripheral library architecture as dsPIC33F devices.
Key features of this part include 256KB of self-programmable Flash with code protection, 16KB SRAM, a 16-channel 10-bit/12-bit ADC (configuration dependent), multiple UART/SPI/I2C peripherals, a 16-bit timer/capture/compare/PWM block, DMA for CPU-offload data movement, and a Real-Time Clock Calendar (RTCC) with external 32.768 kHz crystal support. The 85 I/O pins tolerate 5V input and are 5V output capable on the digital periphery, easing mixed-voltage interfacing to legacy peripherals and sensors.
Architecturally, the PIC24HJ256GP610T-I/PT uses the proven PIC24H core running at 40 MIPS, with a 2-cycle hardware multiply and a divide engine supporting 32-bit math in hardware. A 17-bit x 17-bit single-cycle MAC, 16-bit barrel shifter, and zero-overhead DO/REPEAT loops accelerate DSP-style filtering and PID control loops, while the DMA controller moves ADC samples and UART data without CPU intervention.
Typical applications include BLDC and PMSM motor control, industrial sensor signal conditioning, UPS inverter controllers, building automation HVAC controllers, industrial-grade human-machine interface (HMI) panels, and low-cost audio effects processing. The wide peripheral set and large Flash also suit protocol bridges (e.g. Modbus to CAN) and multi-master communitative scheduling.
When designing with this part, ensure that the 100-pin TQFP land pattern has adequate thermal copper, that AVdd and AVss are cleanly decoupled, and that the 32.768 kHz SOSC crystal load capacitors match the chosen crystal's CL spec. For motor control applications, pair this MCU with a Microchip MCP8024 or TC2xxx gate driver and use the dedicated PWM/ADC trigger routing shown in the datasheet for deterministic current sampling.

主な用途
PIC24HJ256GP610T-I/PT の用途: 7 件s: BLDC and PMSM Motor Control, Industrial Sensor Signal Conditioning, UPS Inverter Controller, Building Automation HVAC Controller, Industrial Human-Machine Interface (HMI), Low-Cost Audio Effects Processing, Modbus/CAN Protocol Bridge.
BLDC and PMSM Motor Control
The PIC24HJ256GP610T-I/PT is a strong fit for sensorless or sensored BLDC/PMSM motor control due to its 256KB Flash, 16KB RAM, 40 MIPS throughput, and dedicated 8-output 16-bit PWM block with three duty-cycle generators and configurable fault/shutdown inputs. The 16-channel ADC enables simultaneous current and back-EMF sampling on three-phase motors up to several kW, while the 8-channel DMA moves ADC samples into memory without CPU intervention. Hardware QEI (Quadrature Encoder Interface) and 16-bit timers handle encoder feedback at high RPM. The 100-pin TQFP provides 85 I/O - more than enough for gate driver enable signals, brake, fault, and CAN bus lines. Use this MCU with a TC2xxx or MCP8024 gate driver for a complete motor-control subsystem up to 600V DC bus.
おすすめ
Industrial Sensor Signal Conditioning
For multi-channel industrial sensor signal conditioning, the PIC24HJ256GP610T-I/PT integrates 16 ADC channels with DMA, 4 UART, 3 SPI, and 3 I2C peripherals in a single 100-pin TQFP. The 40 MIPS CPU runs linearization, calibration, and digital filtering at the sensor sample rate, while the 256KB Flash holds lookup tables for thermocouple/RTD linearization. The 5V-tolerant digital I/O accepts legacy 5V sensor outputs without level shifters, simplifying board design. The 85 I/O count supports multi-sensor aggregators and Modbus RTU gateways. Pair with a Microchip MCP3421 18-bit ADC or MCP4725 DAC for high-accuracy analog front-end conditioning.
おすすめ
UPS Inverter Controller
The PIC24HJ256GP610T-I/PT serves as the digital controller for UPS and solar inverter systems where its 256KB Flash holds full MPPT, sine-table, and protection algorithms, while the 40 MIPS core updates SPWM at 20 kHz with comfortable margin. Three pairs of complementary PWM outputs drive the H-bridge via a digital isolator, and the fast ADC sampling synchronized to PWM edges enables cycle-by-cycle current limiting. Multiple UARTs route to RS-485 Modbus and USB, while CAN provides optional BMS communication. The 100-pin TQFP is industry-standard for power-conversion boards. Pair with an Isolink ISO5852S gate driver for IGBT/SiC power stages up to 1200V.
おすすめ
Building Automation HVAC Controller
In HVAC and building-automation controllers, the PIC24HJ256GP610T-I/PT aggregates temperature, humidity, CO2, and occupancy sensors over its 3 I2C and 3 SPI buses, then drives modulating damper/valve actuators via PWM and analog outputs. The 256KB Flash accommodates BACnet or Modbus protocol stacks alongside control logic. The RTCC with external 32.768 kHz crystal provides accurate time-of-day scheduling. The 85 I/O count supports multi-zone controllers, and the industrial temperature range (-40C to +85C) handles unconditioned mechanical rooms. For LCD keypads, the Parallel Master Port (PMP) drives graphical displays directly without external controllers.
おすすめ
Industrial Human-Machine Interface (HMI)
For industrial HMI panels, the PIC24HJ256GP610T-I/PT drives a TFT LCD via the integrated PMP/EPMP interface, reads capacitive touch via SPI, and routes RS-485/Modbus to a master PLC. The 256KB Flash supports graphical menu trees and multi-language fonts, while 16KB RAM holds screen buffers. The 85 I/O count supports discrete inputs for keypads, status LEDs, and buzzer outputs. 40 MIPS sustains smooth touchscreen response and animated icons. The 100-pin TQFP is a standard industrial form factor. Pair with an SSD1963 or RA8875 graphics controller for larger displays up to 800x480.
おすすめ
Low-Cost Audio Effects Processing
In audio-effects and consumer audio products, the PIC24HJ256GP610T-I/PT's 40 MIPS core runs reverb, EQ, and dynamics algorithms in real time at 48 kHz sample rate. The integrated 16-bit PWM block plus DMA-driven DAC output drives a class-D amplifier directly, eliminating an external DAC. The I2S or SPI peripherals interface to external audio ADCs. The 256KB Flash stores preset banks and coefficient tables. Use the 85 I/O for front-panel buttons, rotary encoder, and LED rings. For higher-end audio, consider migrating to dsPIC33FJ256GP710A-I/PT (DSP engine, same 100-pin TQFP package).
おすすめ
Modbus/CAN Protocol Bridge
As a Modbus RTU to CAN bus bridge used in industrial machinery, the PIC24HJ256GP610T-I/PT runs both protocol stacks concurrently thanks to its 4 UART (one for RS-485 Modbus) and integrated CAN module. The 256KB Flash holds complete Modbus RTU/TCP and CANopen or J1939 stacks, while the 8-channel DMA moves message buffers without CPU load. The 40 MIPS sustains bus rates up to 1 Mbit/s on both sides with sub-1 ms latency. The 100-pin TQFP provides 85 I/O for status LEDs, address switches, and isolation enable. The industrial temperature range suits factory-floor deployment.

設計ノート
The 100-pin TQFP (12x12 mm) requires a 4-layer PCB with a continuous ground plane under the package for proper thermal and EMI performance. Place 0.1uF decoupling capacitors as close as possible to every Vdd/Vss pair (six pairs on the PIC24HJ256GP610T-I/PT - one for every two supply pins), plus a bulk 10uF tantalum or ceramic on each of the three Vdd rails. AVdd and AVss must be decoupled separately from the digital Vdd/Vss pairs to keep ADC noise below 1 LSB at 12-bit resolution. Use a star-ground topology at the AVss pin to isolate analog return currents from switching digital ground.
Do not route any high-frequency digital signals (PWM, SPI clock) across the analog Vdd/AVss region, or the ADC SNR will degrade by 3-5 LSB. Configure the JTAG/ICSP pins (PGECx/PGEDx) as remappable peripheral pins only after disabling in-circuit debugging, otherwise debugger conflicts will silently reprogram Flash. When using the 32.768 kHz SOSC crystal for RTCC, load capacitors must match the crystal's CL specification - typically 6-10pF total including stray capacitance. A wrong load capacitor combination shifts RTCC timing by 30-60 seconds per day.
The PIC24HJ256GP610T-I/PT draws approximately 70-90 mA active at 40 MIPS and 3.3V with all peripherals on. For low-power applications, configure the device into Sleep or Idle mode using the built-in PMD (Peripheral Module Disable) registers - Sleep current is around 50-100 uA, with RTCC operating. Estimated: total active power at 40 MIPS, Vdd=3.3V, I_core=80mA, P = 3.3V * 0.08A = 264 mW. Add a 100-220 uF bulk capacitor on Vdd to handle inrush during PLL start-up and wake-from-Sleep transitions.
Keep the primary 8 MHz crystal within 5 mm of pins OSC1/OSC2, and surround the crystal traces with a ground pour to reduce EMI susceptibility. For motor-control designs, route the three PWM pairs (PWM1H/L through PWM3H/L) as closely matched-length differential pairs to the gate driver to maintain timing symmetry. Place the gate driver's bootstrap capacitors and gate resistors within 10 mm of the driver IC, not near the MCU. Estimated trace delay for a 25 mm trace at 150 ps/in: ~1.5 ns - negligible for 20 kHz PWM but consider ground bounce for >100 kHz designs.
