PIC24HJ128GP310A-I/PT 개요
A 16-bit microcontroller (MCU) is an embedded processor with a 16-bit-wide datapath, register file, ALU and instruction word, positioned between 8-bit MCUs and 32-bit ARM Cortex-M parts in the embedded hierarchy. The PIC24H sits above 8-bit PIC16/PIC18 parts and below 32-bit PIC32 MCUs within Microchip's portfolio, targeting deterministic real-time control with C-friendly compiler support, hardware DSP-like multiply, and rich motor-control peripherals.
Key features include 8-channel DMA, a 16-bit timer/counter engine, up to 8 PWM outputs with dedicated time bases, 10/12-bit ADC options (one A/D converter shared across multiple channels), two UART, two SPI, two I2C, one 16-bit parallel master port, and boundary-scan (JTAG) for in-circuit test. The modified Harvard architecture with separate program and data paths gives deterministic interrupt latency under 10 cycles, critical for power conversion and motor control loops.
The 100-pin TQFP device is pin-compatible with the dsPIC33F DSC family, providing a seamless migration path from fixed-point MCU to full DSP when applications evolve to require MAC-intensive routines. Internal phase-locked loop multiplies an external 8 MHz crystal to the full 40 MHz system clock.
Typical applications include industrial motor control (BLDC, PMSM and ACIM drives), digital power conversion (PFC + LLC controllers), factory automation PLCs, sensor signal conditioning and medical instrumentation front-ends. The wide peripheral mix suits multi-loop PID control with high update rates.
When designing with this device, allocate the dedicated DMA channels carefully - misassignment between ADC and PWM can starve high-priority transfers. A 10 uF bulk plus 0.1 uF decoupling capacitor per power pin is the minimum recommendation.

일반적인 애플리케이션
PIC24HJ128GP310A-I/PT 적합 용도: 6 애플리케이션s: Industrial BLDC / PMSM Motor Control, Digital Power Conversion (PFC + LLC), Factory Automation PLC Modules, Sensor Signal Conditioning, Medical Instrumentation Front-End, Renewable Energy MPPT Controllers.
Industrial BLDC / PMSM Motor Control
The PIC24HJ128GP310A-I/PT's 40 MIPS throughput sustains a 20 kHz FOC current loop with field-weakening, while its up-to-8 PWM channels drive a 3-phase inverter with programmable dead-band. The 8-channel DMA offloads ADC sampling from the CPU, and the 16-bit PWM resolution (TCY = 25 ns at 40 MHz) gives precise duty control at low RPM. Designers can implement sensored or sensorless FOC using Microchip's AN1078 and AN1299 reference designs, and migrate to dsPIC33F later if DSP routines become critical.

Digital Power Conversion (PFC + LLC)
The PIC24HJ128GP310A-I/PT is widely used in digital PFC and LLC half-bridge controllers where 40 MIPS delivers average-current-mode control at 100 kHz switching. The on-chip 10/12-bit ADC with hardware trigger from PWM simplifies valley/current sampling, while the 8-channel DMA moves conversion results into RAM without CPU intervention. Compared with analog UC3842 controllers, this MCU enables adaptive loop compensation, soft-start profiling, and PMBus telemetry via I2C, all in one 100-pin TQFP package.

Factory Automation PLC Modules
For PLC digital-input / analog-input modules, the PIC24HJ128GP310A-I/PT offers 16 KB SRAM to buffer Modbus or EtherCAT-fragmented packets and 128 KB flash for IEC 61131-3 style logic engines. Its two UART, two SPI and two I2C ports easily handle isolated RS-485 transceivers plus SPI-based ADC chains. The industrial -40C to +85C rating matches IEC 61131-2 ambient requirements for cabinet-mounted controls.
추천
Sensor Signal Conditioning
In precision sensor front-ends, the PIC24HJ128GP310A-I/PT combines a 12-bit ADC, DMA-driven oversampling, and 40 MIPS compute for digital filtering (FIR/IIR). The parallel master port can drive external FIFO/DSP co-processors or LCD displays. With JTAG boundary-scan, in-circuit test coverage is achievable on dense mixed-signal boards, reducing manufacturing test cost.

Medical Instrumentation Front-End
Battery-powered medical instrumentation - patient monitors, infusion pumps, portable ultrasound - benefits from the PIC24HJ128GP310A-I/PT's 3.3 V low-power operation, deterministic interrupt latency, and rich PWM for waveform generation. The -40C to +85C industrial range covers most clinical environments. IEC 60730 / IEC 60601 self-test routines fit in 128 KB flash with library support from Microchip's Class B/C software package.

설계 노트
Place a 10 uF tantalum or ceramic bulk capacitor near the PIC24HJ128GP310A-I/PT VDD pins, plus a 0.1 uF X7R decoupling capacitor on every VDD/VDDC pair. The internal PLL draws fast transient current when switching between CPU and peripheral clocks; insufficient bulk capacitance causes core-voltage droop and ADC reference noise. Tie all unused VDD pins to the 3.3 V rail per the datasheet, never leave them floating.
The 100-pin TQFP (PT) package has a thermal resistance theta_JA of approximately 45-50 C/W on a standard 4-layer JEDEC test board. At 40 MIPS with peripherals active, worst-case core power is around 60-80 mW, so a 5-7C junction rise above ambient is realistic. For sealed enclosures or above 70C ambient, add thermal vias under the exposed pad (if present) or copper pours on top layer for improved dissipation. Estimated: theta_JA = 47 C/W, P = 75 mW, delta_T = 3.5C above ambient at 25C.
Route the 40 MHz system clock trace on the top layer with a continuous ground reference and keep it shorter than 25 mm to avoid EMI. Place the 8 MHz crystal within 5 mm of OSC1/OSC2 and surround it with a ground guard ring tied to analog ground. PWM output traces should be kept short and away from ADC analog traces; if they must cross, do so at 90 degrees. The parallel master port (PMP) data bus is high-speed - route as a matched-length group.
Configuration bits (fuses) must be set BEFORE first flash erase/programming - incorrect oscillator configuration (e.g. selecting HS instead of XT) bricks the part until ICSP recovers it. Do not exceed 3.6 V on any VDD pin during flash programming or ADC readings saturate. The PIC24HJ128GP310A-I/PT has 8 DMA channels - do not assign DMA0 to both ADC and PWM simultaneously, as it starves high-priority transfers.
Separate analog and digital grounds: AGND and DGND should meet only at one point near the MCU. For mixed-signal designs using the internal ADC, place the analog reference decoupling capacitor (typically 0.1 uF + 10 uF) directly at AVdd/AVss pins. PWM-driven power stages should have their own ground return path back to the bulk capacitor to avoid injecting switching noise into the MCU ground reference.
