PIC24HJ16GP304-I/PT Overview
A 16-bit microcontroller is a single-chip processor that combines a 16-bit CPU datapath, on-chip Flash, SRAM, and a rich set of peripherals in a single IC, sitting in the hierarchy MCU -> microcontroller -> embedded processor -> semiconductor. The PIC24H family targets high-speed, repetitive-computation and closed-loop-control applications that exceed the performance envelope of 8-bit MCUs while remaining lower cost and lower power than 32-bit ARM Cortex-M parts. The PIC24HJ16GP304 is the 16 KB Flash / 28- to 44-pin variant of the dsPIC33F-compatible PIC24HJ16GP302 family.
Key differentiating specifications include 40 MIPS sustained throughput from a 20 MHz external crystal (4x PLL), 16 KB self-programmable Flash with ECC, hardware CRC engine, JTAG boundary scan, and five 16-bit timers. The PPS fabric allows nearly every digital peripheral to be routed to a wide selection of physical pins, simplifying PCB layout and reducing muxing constraints. Two UART/SPI/I2C modules, two CAN 2.0B controllers, and a 6-channel PWM/OC make it well suited to multi-protocol industrial nodes.
The architecture uses a 24-bit fixed-width instruction set with 16-bit datapath registers, separate program and data buses, and a 17-bit x 17-bit hardware multiplier that delivers single-cycle MAC operations critical for digital signal processing routines. A two-level pipeline and deterministic interrupt response free of Flash wait-state stalls let the device sustain real-time control loops at the 40 MIPS ceiling without jitter.
Typical applications include industrial motor control, sensor data acquisition nodes, automotive body and chassis subsystems, digital power conversion, and USB-less consumer appliances that require CAN, UART, and SPI connectivity. The wide operating temperature range of -40C to +85C supports both commercial and industrial deployments.
When designing with this part, allocate at least one analog pin for Vcap decoupling and follow Microchip's recommended 10 uF + 0.1 uF bulk bypass topology to ensure core voltage regulator stability. Programmers should configure the JTAGEN fuse before relying on boundary-scan for production test, since boundary-scan is disabled by default to free the four JTAG pins for general I/O use.

Typical Applications
PIC24HJ16GP304-I/PT is suitable for 6 applications: Industrial Motor Control, Sensor Data Acquisition Nodes, Automotive Body and Chassis Modules, Digital Power Conversion (SMPS), Industrial Communication Gateways, Consumer Appliance Controllers.
Industrial Motor Control
The PIC24HJ16GP304-I/PT is well suited for BLDC and PMSM motor control drives because of its 40 MIPS throughput, six PWM channels, and 12-bit ADC with up to 13 channels that allow simultaneous sampling of motor phase currents. The 16 KB Flash holds a sensorless FOC state machine and commutation lookup tables, while the PPS fabric maps PWM outputs to any I/O pin for flexible PCB routing. Placed in a vector-controlled drive it sustains 20 kHz PWM with 1-cycle interrupt latency, leaving CPU margin for CANopen or EtherCAT communication. Compared with a 32-bit ARM Cortex-M0+, the PIC24H deterministic interrupt response is preferable for hard real-time torque loops.
Recommended
Sensor Data Acquisition Nodes
The PIC24HJ16GP304-I/PT serves as a sensor hub that aggregates analog inputs from thermocouples, load cells, and pressure sensors. Its 12-bit ADC with up to 13 channels covers a typical 4- to 8-sensor industrial node, while the 2 KB SRAM buffers raw samples before UART/SPI transmission to a host. The 40 MIPS CPU can run digital filtering and linearization at full sample rate without taxing the main loop. Compared with an 8-bit PIC16, the PIC24HJ16GP304 provides 5x the throughput and CAN 2.0B for direct industrial bus attachment.
Recommended
Automotive Body and Chassis Modules
The PIC24HJ16GP304-I/PT is used in automotive body controllers, lighting modules, and HVAC actuators where 40 MIPS throughput and dual CAN 2.0B interfaces are required. Its 35 digital I/O pins drive multiple LED matrices, MOSFET half-bridges, and stepper motors without external muxing. The industrial -40C to +85C temperature range covers cabin and under-hood applications, while the PIC24HJ16GP304-H/PT variant extends to +150C for transmission-mounted designs. Pair with an external CAN transceiver for robust OBD-II communication.
Recommended
Digital Power Conversion (SMPS)
The PIC24HJ16GP304-I/PT drives digital-controlled switch-mode power supplies at switching frequencies up to 500 kHz with deterministic loop response. Its high-resolution PWM (six channels) generates phase-shifted full-bridge or interleaved PFC waveforms, while the 12-bit ADC samples output voltage and current with sub-microsecond latency. The 16 KB Flash holds digital compensator coefficients and soft-start state machines. Compared with analog UCC28C42 control, the PIC24HJ16GP304 enables programmable compensation, telemetry, and adaptive dead-time control in a single IC.
Recommended
Industrial Communication Gateways
The PIC24HJ16GP304-I/PT acts as a protocol bridge between CAN, UART, SPI, and I2C buses in industrial nodes. The two CAN 2.0B controllers let it serve as a CAN-to-Modbus or CAN-to-USB gateway, while two UART/SPI/I2C peripherals attach to wireless modules or sensors. The 40 MIPS throughput sustains full CAN bus utilization with time-stamped message handling and protocol translation. Industrial -40C to +85C rating supports cabinet-mounted deployments.
Recommended
Consumer Appliance Controllers
The PIC24HJ16GP304-I/PT controls washing machines, dishwashers, induction cooktops, and other consumer appliances where its 40 MIPS CPU runs sensor-fusion algorithms, user-interface handling, and motor control simultaneously. The 35 I/O pins drive keypads, displays, and triac-fired loads without external muxing. The 16 KB Flash holds appliance-specific firmware including safety routines and fault diagnostics. Compared with 8-bit PIC16F parts, the PIC24HJ16GP304 supports USB-less connectivity through CAN and offers 5x the throughput for modern UI rendering.

Design Notes
Place a 10 uF bulk capacitor in parallel with a 0.1 uF ceramic on Vcap (pin 27) to stabilize the internal 1.8 V core LDO. According to the Microchip datasheet, insufficient Vcap decoupling causes POR misbehavior and Flash read errors under high CPU load. Each VDD/VSS pair also requires its own 0.1 uF local ceramic placed within 3 mm of the pin to minimize switching noise injection from the digital core.
Route the 20 MHz crystal traces (OSC1/OSC2) as short, symmetric, ground-shielded traces with the load capacitors placed within 2 mm of the IC. Avoid routing high-current switching signals (PWM outputs, triac drivers) parallel to the oscillator traces to prevent injection locking. Place the analog VDD/AVSS star-ground connection at a single point to keep ADC reference noise below 1 LSB at 12-bit resolution.
Do not forget to clear the JTAGEN fuse in the configuration bits if JTAG pins (PGEC1/PGED1) must be used as general-purpose I/O. By default, JTAG is enabled and four pins are reserved for boundary-scan testing. Configuring JTAGEN=OFF frees these pins for analog or digital I/O use, but disables in-circuit debugging through the JTAG interface. Use the ICSP interface (PGEC2/PGED2) for programming in production to retain general-purpose I/O access.
