PIC24HJ32GP204-E/PT 概要
A PIC24H 16-bit microcontroller is a member of Microchip's 16-bit MCU family built on a modified Harvard architecture. It combines a 16-bit data path with a 24-bit instruction path, which improves code density for C compilers while supporting DSP-style addressing modes. PIC24H devices sit in the hierarchy MCU -> 16-bit MCU -> PIC24H family -> microcontroller -> embedded processor, and they target applications requiring deterministic real-time control at moderate clock rates without the cost of higher-performance 32-bit parts.
Key features include 21 digital I/O pins with peripheral pin select (PPS) functionality, 5V-tolerant inputs, 4 mA sink/source capability, and open-drain outputs capable of pulling up to 5V. The device integrates three 16-bit timers (pairable into one 32-bit timer), two output compare modules, an input capture module, two UART, SPI, and I2C peripherals, a 10/12-bit ADC, and a 16-bit comparator. The PPS block remaps most digital peripherals to a wide choice of pins, simplifying PCB routing and BOM consolidation.
The 40 MIPS core, hardware multiplier, and zero-overhead loop control make the PIC24HJ32GP204-E/PT suitable for digital control loops, sensor signal processing, and communication bridges. Its instruction set is optimized for compiled C, which lowers firmware development cost versus legacy 8-bit PIC architectures while retaining Microchip's ecosystem of MPLAB X IDE, MPLAB XC16 compiler, and dsPIC/PIC24 plug-in modules.
Typical applications include industrial sensor signal conditioning, motor control pre-drivers, HVAC fan and pump controllers, building-automation nodes, point-of-sale terminals, and medical instrumentation front-ends. The combination of 32 KB Flash, 2 KB RAM, and 5V-tolerant I/O enables direct interfacing to legacy 5V sensors and actuators without external level shifters.
When designing with this part, verify that the chosen 44-pin TQFP footprint exposes the required VDD/VSS pair counts and the dedicated PGED/PGEC programming pins. Place a 10 uF bulk + 0.1 uF decoupling capacitor pair adjacent to each VDD pin and keep the analog reference traces short and guarded.

主な用途
PIC24HJ32GP204-E/PT の用途: 6 件s: Industrial Sensor Signal Conditioning, HVAC Fan and Pump Motor Pre-Driver, Building Automation Control Node, Medical Instrumentation Front-End, Point-of-Sale Terminal and Peripheral Controller, Communication Bridge / Protocol Converter.
Industrial Sensor Signal Conditioning
The PIC24HJ32GP204-E/PT fits industrial sensor signal conditioning because its 12-bit ADC at 1.1 Msps, 5 V-tolerant digital I/O, and 40 MIPS PIC24H core can sample and filter multiple analog channels in real time. It directly interfaces to 5 V legacy sensor bridges (load cells, RTDs, pressure transducers) without external level shifters, reducing BOM count. PPS remaps the ADC trigger to any digital pin, easing PCB layout for multi-channel data-acquisition front-ends. Place a 0.1 uF ceramic bypass within 5 mm of each VDD pin to keep ADC SNR within datasheet limits.
おすすめ
HVAC Fan and Pump Motor Pre-Driver
The PIC24HJ32GP204-E/PT is well-suited as a motor pre-driver controller for HVAC fans and pumps because its 40 MIPS core, three 16-bit timers (pairable into one 32-bit timer), and two output-compare channels generate the PWM timing signals for a downstream three-phase inverter. Peripheral pin select allows the PWM outputs to land on any digital I/O pin, simplifying routing to gate-driver ICs. The extended -40C to +125C temperature grade supports rooftop and outdoor installations. The 32 KB Flash and 2 KB SRAM accommodate sensored field-oriented-control (FOC) or trapezoidal commutation state machines.
おすすめ
Building Automation Control Node
The PIC24HJ32GP204-E/PT functions as a building-automation node for lighting, blinds, and HVAC control because its two UART, SPI, and I2C peripherals natively interface to RS-485 transceivers, BACnet/MODBUS modules, and LED-driver pixies. The 5 V tolerant I/O eliminates level shifters when connecting to 24 V HVAC actuator boards via opto-couplers. PPS reassigns the UART and SPI to any pair of pins, allowing a single PCB layout to support multiple communication profiles. The 32 KB Flash holds BACnet or KNX stack fragments and room-control logic.
おすすめ
Medical Instrumentation Front-End
The PIC24HJ32GP204-E/PT serves medical instrumentation front-ends (glucometers, pulse oximeter bias controllers, point-of-care analyzers) where its 12-bit ADC, two analog comparators, and 40 MIPS core digitize low-level analog signals with deterministic latency. The extended temperature grade supports sterilization and refrigeration thermal cycling. The 5 V tolerant inputs accept signals from legacy op-amp front-ends running on 5 V rails. Firmware runs at deterministic 40 MIPS, simplifying FDA/IEC 62304 software safety-class arguments.
おすすめ
Point-of-Sale Terminal and Peripheral Controller
The PIC24HJ32GP204-E/PT controls point-of-sale (POS) peripherals such as receipt printers, barcode scanners, and customer displays because its two UARTs connect to serial printers and scanners, SPI drives a graphic OLED display, and I2C manages a capacitive keypad or NFC reader. PPS remaps peripherals across the 21 I/O pins so a single PCB supports multiple SKU variants. The 40 MIPS core handles the encryption and display-refresh load. The extended temperature grade is useful for outdoor payment kiosks.
おすすめ
Communication Bridge / Protocol Converter
The PIC24HJ32GP204-E/PT acts as a communication bridge between UART, SPI, and I2C domains in industrial gateways and protocol converters because its three independent serial peripherals and 40 MIPS throughput can translate Modbus RTU to Modbus TCP framing or CAN-to-UART telemetry at real-time rates. The 32 KB Flash stores protocol state machines, and 2 KB RAM buffers packet queues. The extended temperature grade supports roadside and substation environments where wider thermal swings occur.

主な差別化要因

- Pin-compatible migration path to dsPIC33 with DSP engine （vs PIC24HJ16GP304-I/PT)

設計ノート
Place a 10 uF bulk + 0.1 uF ceramic decoupling capacitor pair adjacent to each VDD pin (44-pin TQFP has two VDD/VSS pairs at pins 9/10 and 15/16). AVDD/AVSS for the ADC require an additional 0.1 uF ceramic with traces kept short (<5 mm) to maintain ADC SNR within datasheet limits. Connect VREF+ to a dedicated low-noise LDO such as MCP1700 when ADC accuracy below 10-bit ENOB is required.
Estimate: At 40 MHz with all peripherals active and I/O sourcing 4 mA per pin, average IDD is approximately 30 mA and maximum IDD with all peripherals running at maximum toggle rate can reach 70 mA. Power dissipation is therefore approximately 70 mA x 3.3 V = 231 mW; thermal rise is negligible (theta_JA around 40 C/W for 44-pin TQFP). No external heatsink is required. Always respect the datasheet maximum ratings rather than relying on estimates.
The 'E' suffix denotes -40C to +125C extended industrial temperature grade. Do not substitute 'I' (-40C to +85C) or 'H' (0C to +70C) suffixes without verifying the deployment environment. The PPS mapping must be configured in firmware before the first use of any remappable peripheral; calling a UART/SPI/I2C function without a PPS unlock sequence causes silent no-op behavior. Verify the unlock sequence in the PIC24H Family Reference Manual section 'Peripheral Pin Select'.
Route the crystal traces (OSC1/OSC2, pins 17/18) as short as possible with a guard trace tied to ground, and place the load capacitors within 3 mm of the MCU. Avoid routing high-speed digital signals under the crystal can. The PGED1/PGEC2 pair (pins 21/22) for ICSP should be routed to an in-circuit-programming header accessible without disturbing the PCB. Avoid placing the ICSP header too close to switching power inductors.
