PIC24HJ16GP304-H/ML 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, volatile and non-volatile memory, programmable peripherals, and clock circuitry. The PIC24H is a digital signal controller-class MCU family: it combines a 16-bit datapath with DSP-oriented instructions while retaining the deterministic interrupt response of a traditional microcontroller. Within the broader taxonomy, the PIC24H sits between 8-bit PIC MCUs and 32-bit ARM Cortex-M parts, offering higher computational headroom than 8-bit devices while remaining easier to deploy than 32-bit platforms for legacy code bases and motor-control applications.
Key features include 16 KB Flash with self-programmability, 2 KB SRAM, 30 MIPS sustained throughput at 3.3V, a 4-channel DMA controller, configurable 5V-tolerant digital I/O, and integrated nanoWatt power management. The -H suffix denotes the High temperature grade (industrial -40C to +150C), and the /ML designator specifies the lead-free 44-pin QFN (8x8 mm) package. The device is pin-compatible with the dsPIC33F family and shares a high degree of architectural compatibility with the dsPIC30F family, easing firmware migration between the three lines.
The modified Harvard architecture separates program and data memory buses, allowing concurrent instruction fetch and data access. The 24-bit instruction word accommodates a variable-length opcode field with built-in DSP support, enabling single-cycle MAC (multiply-accumulate) operations. Five cycle interrupt latency and a hardware multiplier dedicated to DSP operations make the device well suited to closed-loop control where determinism matters more than peak throughput.
Typical applications include industrial motor control (BLDC, PMSM, and stepper drives), digital power conversion (PFC and LLC controllers), sensor signal conditioning, building automation, automotive body electronics, and medical instrumentation. The industrial temperature grade extends deployment to outdoor, under-hood, and harsh-environment designs that exceed consumer-grade -40C to +85C limits.
When designing with this device, allocate the PPS remap carefully: every peripheral signal can be routed to almost any digital I/O pin, but two signals cannot share a pin simultaneously. Plan the pin map in the source header before schematic entry.

主な用途
PIC24HJ16GP304-H/ML の用途: 6 件s: Industrial BLDC Motor Control, Digital Power Conversion (PFC/LLC), Sensor Signal Conditioning and IoT Edge, Automotive Body Electronics, Building Automation and HVAC, Medical Instrumentation.
Industrial BLDC Motor Control
The PIC24HJ16GP304-H/ML drives sensorless and Hall-sensor BLDC motors up to 40 MIPS, providing the 5-cycle deterministic interrupt latency required for field-oriented control loops at 20 kHz PWM. Its 16-bit datapath with 24-bit DSP-friendly instructions, plus Peripheral Pin Select routing for six PWM outputs, three analog comparator inputs, and quadrature encoder interfaces, fits 3-phase inverter PCBs without glue logic. The -40C to +150C high grade handles under-hood industrial environments. Compared with software-emulated MAC on Cortex-M0, the PIC24H's single-cycle 16x16 hardware multiplier keeps loop closure tight while reducing firmware complexity for legacy PIC code bases.
おすすめ
Digital Power Conversion (PFC/LLC)
The PIC24HJ16GP304-H/ML implements digital PFC and LLC resonant converters where deterministic 5-cycle interrupt latency and 40 MIPS throughput provide stable closed-loop regulation at 100 kHz switching. Its 4-channel DMA controller offloads ADC sample transfers from the CPU, freeing cycles for control math. The 16-bit ADC resolution available on related family members plus 12-bit ADC on this part feeds current/voltage loops. Peripheral Pin Select remaps SPI and UART for PMBus telemetry, while the 44-pin QFN keeps the digital controller footprint below 64 mm squared - smaller than most analog UCC25640 controllers with equivalent feature sets.
おすすめ
Sensor Signal Conditioning and IoT Edge
The PIC24HJ16GP304-H/ML integrates sensor analog front-end sampling, digital filtering, and protocol translation in a single 44-pin QFN device for IoT edge nodes. Its 12-bit ADC with multiple channels handles thermocouple, strain gauge, and 4-20 mA inputs directly; UART/SPI/I2C peripherals bridge to wireless modules like LoRa or Sub-GHz transceivers. nanoWatt power management modes drop quiescent current below 30 uA in sleep, extending battery life in remote sensor deployments. Peripheral Pin Select lets engineers route I2C or UART to any digital I/O, simplifying PCB layout when connectors are fixed but pinout flexibility is desired for variant SKUs.
おすすめ
Automotive Body Electronics
The PIC24HJ16GP304-H/ML's -40C to +150C high temperature grade (H suffix) qualifies it for under-hood and cabin body-electronics modules: body controllers, HVAC flaps, mirror adjusters, lighting controllers, and seat modules. The 40 MIPS throughput drives LIN/CAN stacks via external transceivers, while PPS remapping simplifies PCB layout reuse across multiple vehicle variants. Flash self-programmability supports OTA bootloader upgrades via CAN or UART. Compared with commercial -40C to +85C parts, the H grade derates junction-to-ambient thermal margins by 30 percent, so copper area on the QFN ground paddle must be sized accordingly in sealed automotive enclosures.
おすすめ
Building Automation and HVAC
Building automation controllers - BACnet gateways, smart thermostats, VAV damper actuators - benefit from the PIC24HJ16GP304-H/ML's mix of 16-bit math throughput, multiple UART channels for RS-485 multi-drop, and 16-bit timer granularity for HVAC PID loops. The 16 KB Flash fits BACnet/IP or Modbus stacks with headroom for custom application logic; 2 KB SRAM handles packet buffers for typical building automation transactions. The high temperature grade supports rooftop and mechanical-room deployments where ambient exceeds 70C. PPS remap allows the same silicon to populate different PCB variants for different HVAC zone configurations.
おすすめ
Medical Instrumentation
Patient monitors, infusion pumps, and benchtop diagnostic instruments leverage the PIC24HJ16GP304-H/ML's deterministic interrupt latency and DSP-friendly instructions for waveform analysis, PID-controlled actuators, and safety-critical loops. The modified Harvard bus prevents data corruption during code execution - a Class B IEC 60730 consideration for medical firmware. 16 KB Flash accommodates Class B self-test libraries plus application code; the high temperature grade enables sterilization-tolerant designs. Compared with 8-bit PIC MCUs, the 16-bit datapath doubles ADC sample averaging precision and reduces quantisation noise in low-amplitude biosignal acquisition.

設計ノート
The PIC24HJ16GP304-H/ML has separate analog (AVDD/AVSS) and digital (VDD/VSS) supply pins on the 44-QFN package. Tie all VDD pins together and all VSS pins together with a star-ground topology under the chip. Place a 10 uF bulk + 0.1 uF ceramic + 1 nF HF bypass network within 5 mm of the VDD pins. A ferrite bead between AVDD and VDD is recommended for ADC noise isolation, per Microchip datasheet 70289A Section 25.0.
Estimated: the 44-pin QFN (8x8 mm) has a thermal resistance theta_JA of approximately 30 C/W on a 4-layer JEDEC test PCB. The -H temperature grade allows junction up to +150C; at 85C ambient with 100 mW dissipation, junction rise is approximately 3C, leaving substantial margin. For sealed enclosures with no convection, expose the EP (exposed pad, pin 44) thermal paddle to a 25 mm squared copper area stitched with 0.3 mm thermal vias to the inner ground plane for rated performance.
Place the ICSP programming header (PGEC1/PGED1 on pins 43-44) on a 0.1-inch header footprint accessible without removing the board. Add a 4.7 kohm pull-up on MCLR (pin 28) to VDD for production programming, and route the ICSP traces away from PWM signals to avoid noise injection during debug. The exposed pad (pin 44 / EP) MUST be soldered to a 6x6 mm copper pad with thermal via array, otherwise the part will overheat and reliability will be compromised.
Peripheral Pin Select (PPS) remap is configured AFTER power-on in firmware. If a peripheral signal is not visible on the oscilloscope immediately, the most common cause is missing PPS unlock sequence in the initialization code. Each PPS register write requires unlocking the IOLOCK bit, configuring the mapping, then re-locking. Failing to re-lock disables further writes and triggers silent debug failures. Also note that two peripherals cannot share a pin - if SPI1_SDO and UART1_TX are routed to the same pin, only one will function.
コンプライアンス情報
RoHS and lead-free per Microchip product page. AEC-Q100 qualification is NOT formally claimed for the -H temperature grade; the H suffix denotes wide-temperature industrial grade (-40C to +150C), not automotive qualification. For AEC-Q100-qualified PIC24H parts, review Microchip's automotive-grade portfolio separately.
