PIC24HJ256GP206AT-I/PT 概要
What is a 16-bit microcontroller? A 16-bit MCU is a single-chip computer whose datapath, registers, and ALU are 16 bits wide, offering higher computational throughput and code density than 8-bit parts while consuming less power than 32-bit cores. The PIC24H family belongs to the broader category of Microchip DSC (Digital Signal Controller) derivatives and occupies the mid-range of Microchip's performance pyramid: PIC -> 16-bit PIC24 -> PIC24H (high-performance) -> 32-bit PIC32. The PIC24H is widely used in motor control, power conversion, industrial sensing, and CAN-connected automotive/industrial nodes.
Key differentiating features include 40 MIPS execution from a modified Harvard core with C-compiler-optimized instruction set, 16 KB unified data RAM accessible from DMA and the CPU, and an on-chip 16-channel 12-bit ADC capable of 500 ksps. The device also provides a 16-bit timer/capture/compare module set, hardware ECAN 2.0B for automotive/industrial networks, and a Peripheral Pin Select (PPS) mechanism that allows flexible remapping of digital peripherals to any I/O pin.
Architecture details: The PIC24HJ256GP206A uses a 16-bit modified Harvard architecture with separate program and data paths, a 24-bit instruction word, and a hardware multiplier (17-bit x 17-bit single-cycle). The core supports 84 instructions including DSP-aware addressing modes, enabling efficient FFT and FIR filtering without off-chip DSP silicon. PPS allows most digital peripherals to be mapped onto a wide choice of pins, easing PCB layout.
Typical applications include industrial sensor conditioning and CAN node interfaces, motor control driver boards (BLDC, stepper, PMSM), HVAC and building automation controllers, automotive body and chassis ECUs, medical instrumentation front-ends, and USB device/HID peripherals when paired with an external transceiver.
When designing with this part, reserve at least one PPS-capable pin group for the UART/SPI/I2C peripherals you intend to use, and verify the 3.3 V rail regulation (the device does not include an internal LDO for core supply). For new designs consider the PIC24HJ256GP610A successor family for higher analog integration.

主な用途
PIC24HJ256GP206AT-I/PT の用途: 7 件s: Industrial Sensor Conditioning and CAN Node, BLDC / PMSM Motor Control Drive, HVAC and Building Automation Controller, Automotive Body and Chassis ECU, Medical Instrumentation Front-End, USB Device/HID Peripheral, Power Conversion Digital Controller.
Industrial Sensor Conditioning and CAN Node
The PIC24HJ256GP206AT-I/PT is well suited for industrial 4-20 mA and 0-10 V sensor conditioning nodes connected via ECAN 2.0B. Its 16-channel 12-bit ADC at 500 ksps captures multi-sensor data simultaneously, while hardware ECAN offloads the protocol stack from the CPU. The 40 MIPS core executes filtering and linearization in real time, and the 256 KB Flash accommodates full Modbus/CANopen protocol libraries. Industrial temperature grade (-40C to +85C) and 3.3 V operation match PLC and field-transmitter rails.
おすすめ
BLDC / PMSM Motor Control Drive
The PIC24HJ256GP206AT-I/PT serves as the main controller in BLDC, PMSM, and stepper motor drives. Five 16-bit timers provide up to 7.5 ns PWM resolution at 40 MIPS, supporting field-oriented control (FOC) at 20-40 kHz switching. The 12-bit ADC at 500 ksps synchronizes current sensing with PWM center, while the hardware multiplier accelerates Clarke/Park transforms. 256 KB Flash stores vector tables and speed-loop firmware, and 16 KB RAM buffers trajectory lookups without external memory.
おすすめ
HVAC and Building Automation Controller
HVAC and building automation controllers benefit from the PIC24HJ256GP206AT-I/PT's 16 KB RAM (for Modbus/BACnet stacks), ECAN interface (for BACnet MS-TP), and dual UART/SPI for sensor and display buses. The 40 MIPS core runs proportional-integral climate loops with sub-millisecond period, and 256 KB Flash supports full BACnet/IP or LonWorks stacks. Industrial -40C to +85C temperature rating covers mechanical room environments with no additional conditioning.
おすすめ
Automotive Body and Chassis ECU
The PIC24HJ256GP206AT-I/PT is used in non-safety automotive body and chassis ECUs such as HVAC controls, lighting modules, and seat controllers. Hardware ECAN 2.0B interfaces to the vehicle CAN bus at 500 kbps, while the 12-bit ADC reads potentiometers, thermistors, and current shunts. 256 KB Flash supports AUTOSAR-lite stacks and OEM-specific diagnostic services. For under-hood or safety applications, select the PIC24HJ256GP206AT-E/PT extended-temperature variant (-40C to +125C).
おすすめ
Medical Instrumentation Front-End
Medical instruments such as portable pulse oximeters, spirometers, and patient-monitoring front-ends leverage the PIC24HJ256GP206AT-I/PT's 12-bit ADC for analog signal acquisition and DSP-class 16-bit core for FIR/IIR filtering. The hardware multiplier accelerates FFT-based heart-rate variability algorithms, while PPS allows flexible signal routing on dense analog boards. The 3.3 V low-voltage operation suits battery-powered portable devices, and 16 KB RAM buffers sample windows without external memory.
おすすめ
USB Device/HID Peripheral
USB device-class peripherals (HID, CDC, vendor-specific) pair well with the PIC24HJ256GP206AT-I/PT and an external USB3300 or PIC18 USB transceiver. The 40 MIPS core handles USB interrupt latency comfortably, and the 16 KB RAM accommodates HID report buffers and USB descriptors. 256 KB Flash stores full USB stacks plus application code. PPS remaps USB-attached peripherals to convenient I/O pins, easing PCB layout on small form-factor boards.
おすすめ
Power Conversion Digital Controller
Digital control of switch-mode power supplies (SMPS) such as PFC, LLC, and full-bridge converters is a strong fit for the PIC24HJ256GP206AT-I/PT. The 12-bit ADC samples voltage and current mode signals at 500 ksps with sub-microsecond latency, while the 16-bit timers generate high-resolution PWM for the power stage. Hardware ECAN enables digital-loop telemetry to the host controller. Industrial temperature rating supports telecom and industrial PSU environments.

設計ノート
The PIC24HJ256GP206AT-I/PT operates from a single 3.0-3.6 V supply on pins 18, 36, and 60. Place 100 nF decoupling capacitors within 5 mm of each VDD/VSS pair, plus a bulk 10 uF tantalum or ceramic on the main 3.3 V rail. The core has no internal LDO, so any ripple above 100 mVpk-pk on VDD can couple into the ADC - use a low-noise LDO such as MCP1700 rather than switching regulators for analog signal-chain designs. Estimated: with 40 MIPS core active and all peripherals enabled, IDD is approximately 70 mA; verify with the datasheet IDD vs. frequency curve for your specific configuration.
Use a 4-layer PCB with continuous ground plane beneath the TQFP-64 footprint for best ADC performance and EMI. Route analog signals (AN0-AN15) on the top layer only, with the analog ground plane (kept separate from digital ground) joined at a single point under the MCU. Keep crystal traces (OSC1/OSC2) shorter than 10 mm and guard them with a ground ring. The 64-pin TQFP at 0.5 mm pitch requires 0.2 mm trace/space - standard 4-layer fab processes handle this comfortably.
Three common pitfalls with PIC24H designs: (1) forgetting to configure Peripheral Pin Select (PPS) before first use of any remappable peripheral - remappable pins default to GPIO input only, so UART/SPI will appear silent. (2) leaving the AVDD/VREF+ pin unconnected when using the ADC - VREF+ must be tied to AVDD or a precision reference, otherwise ADC readings drift. (3) Overclocking past 40 MIPS with an external clock outside the PLL range - the PLL requires a 4-8 MHz reference and will fail to lock above this range, causing silent CPU execution at wrong frequency.
Estimated: the 64-pin TQFP package has a theta_JA of approximately 50 C/W on a standard 4-layer JEDEC test board (per Microchip package thermal data). At 70 mA IDD and 3.3 V supply, internal dissipation is approximately 231 mW, yielding a 12 C junction temperature rise above ambient. For enclosed industrial designs operating at 85 C ambient, the junction reaches 97 C - well within the 125 C maximum. No heatsink is required. Always validate the thermal model against your specific PCB copper area.
Reserve PPS-capable pins (RP0-RP15, and remappable RC pins) for peripherals that must move during PCB layout. PPS allows UART, SPI, and other digital peripherals to be mapped to a wide range of pins after PCB layout is complete - this is invaluable when a critical analog pin conflicts with a digital function. Document the PPS mapping in a header file so that firmware changes do not silently break peripheral assignments. Include a 100 kOhm pull-up on MCLR (pin 64) for reliable reset behavior.
