PIC24HJ256GP610AT-I/PT 概要
A 16-bit microcontroller (MCU) is a single-chip computer that processes instructions and data over a 16-bit-wide datapath, delivering higher computational throughput and better C-code density than 8-bit parts while staying lower in cost and power than 32-bit cores. Within the embedded hierarchy it sits as a sub-family of microcontrollers, which themselves belong to the broader category of embedded processors and SoCs used for control-oriented designs. MV201 families like PIC24H are aimed at applications that require deterministic, high-speed repetitive computation such as DSP filtering, motor control and sensor fusion.
Key features include 16 KB SRAM, the PIC24H Harvard architecture with a wide 24-bit instruction path, an integrated DSP engine, multiple 16-bit timers, a 10/12-bit ADC up to 1.1 Msps, and the dsPIC33F pin-compatible migration path. The wide 24-bit instruction word and rich peripheral set enable efficient fixed-point DSP and PID control loops without offloading work to a coprocessor, while the 40 MIPS throughput comfortably handles multi-loop control at 4 kHz switching frequencies.
The architecture uses a 17 x 17-bit hardware multiplier and a 40-bit accumulator, achieving single-cycle MAC operations that accelerate DSP kernels. A robust interrupt controller with configurable priority and vectoring supports deterministic real-time response, and the on-chip DMA engine offloads data movement between the ADC, ECAN and SPI/I2C peripherals, freeing the CPU for control-law execution.
Typical applications include industrial motor control (BLDC, PMSM and ACIM drives), digital power conversion (PFC plus full-bridge control), sensor signal conditioning, automotive body electronics (when paired with the AEC-Q100 grade variant), and embedded connectivity hubs. The wide memory and DSP engine also suit audio processing, predictive maintenance vibration analysis, and grid-tied solar inverters where repetitive math dominates the workload.
When designing, ensure the on-board regulator delivers a stable 3.0-3.6 V rail and respect the 100-pin TQFP layout guidelines - keep the analog AVSS/AVDD pair isolated from the noisy digital supply and place the 0.1 uF + 10 uF bulk capacitors within 6 mm of each pair to keep ADC noise low. Use the ICD 3 or MPLAB REAL ICE probe header for in-circuit debugging and boundary-scan programming.

設計ノート
Provide a clean 3.3 V rail within 3.0 V to 3.6 V from an LDO such as the MCP1700 or a switching regulator with low ripple (< 50 mV pk-pk). Place a 0.1 uF ceramic decoupling capacitor within 3 mm of every VDD/VSS pair and a bulk 10 uF tantalum or ceramic on the main rail. The analog AVDD/AVSS pair must be filtered with a ferrite bead and 10 uF + 0.1 uF decoupling to keep the 12-bit ADC noise floor low; on-chip voltage scaler draws up to 30 mA peak under full DSP load.
Use a 4-layer PCB with a continuous ground plane beneath the TQFP-100 footprint to provide a low-impedance VSS return and reduce EMI. Keep the analog AVDD/AVSS traces short and isolated from the digital switching nodes; route the ECAN, USB and crystal traces over an unbroken ground pour. Place the 20 MHz crystal within 5 mm of the OSC1/OSC2 pins and surround it with a ground guard ring; the 12 pF load caps must be NPX2 for low-loss operation at the 4x PLL output frequency.
The PIC24HJ256GP610AT-I/PT's 40 MIPS core produces fast edge rates on GPIO (5 ns rise/fall) - keep traces shorter than 50 mm or add series damping resistors (33 ohm) on heavily loaded signals. For ECAN and SPI buses exceeding 1 Mbps, use impedance-controlled 50 ohm microstrip routing and place a 120 ohm termination resistor at each end of the CAN bus. The ICD PGC/PGD pins (RB6/RB7) must be guarded by 4.7 kohm pull-ups to VDD to ensure robust in-circuit programming.
Do not drive the MCLR pin low during normal operation - it forces a reset and clears the RAM. The PIC24H requires the on-chip voltage regulator's bulk capacitor on the VDD/VSS pins closest to pin 38 to ensure stable core voltage under DSP transient loads. Do not exceed the absolute maximum 4.0 V on any pin or risk latch-up; use the internal pull-ups on RB<15:0> instead of external resistors when possible. The ADC reference AVREF+ pin must be tied to AVDD for full 12-bit range or to a precise 2.5 V external reference for ratiometric measurements.
At 40 MIPS full load with all peripherals active, the PIC24HJ256GP610AT-I/PT dissipates up to 240 mW. With a TQFP-100 thermal resistance of approximately 38 C/W (theta_JA on 4-layer JEDEC test board), the junction temperature rises about 9 C above ambient at 25 C. For industrial -40C to +85C operation the part maintains at least 20 C thermal margin at maximum ambient, but in enclosed housings above 60 C ambient, provide forced-air cooling or a copper heatsink pad beneath the exposed thermal paddle footprint.
