PIC24HJ16GP304-H/PT 概述
A 16-bit microcontroller (MCU) is an integrated circuit that executes instructions on 16-bit data widths, enabling higher computational throughput and more efficient C-compiler code density than 8-bit parts. The PIC24H family uses a modified Harvard architecture with a 16-bit data path, 24-bit instruction word, and a hardware multiplier, positioning the family in the hierarchy: PIC24H -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. Compared with 8-bit MCUs, the 16-bit core simplifies arithmetic for control loops, ADC sampling, and communication stacks, while still retaining the deterministic interrupt behavior expected in real-time embedded designs.
Key features of the PIC24HJ16GP304-H/PT include 16KB Flash (16K x 24 instruction words), 2KB SRAM, a 10/12-bit Analog-to-Digital Converter, multiple Enhanced Capture/Compare/PWM modules, UART, SPI, and I2C peripherals, and the Cyclic Redundancy Check (CRC) module shared across the PIC24HJ32GP202/204 and PIC24HJ16GP304 family. The 40 MIPS throughput is sustained by a single-cycle hardware multiply and a 16x16-bit divider, supporting high-bandwidth digital control at moderate clock rates.
Typical applications include automotive body and chassis subsystems, industrial motor control, sensor conditioning, point-of-load conversion, lighting controllers, and human-machine interface panels. The 44-pin TQFP footprint provides ample GPIO for multi-channel sensing and actuator drive, while the 16-bit core simplifies the implementation of PI/PID control algorithms and digital filtering.
When designing with this device, ensure your supply decoupling and the recommended 4 MHz to 20 MHz crystal/oscillator network per the datasheet. Use the ICSP programming interface for in-circuit firmware updates, and confirm that the -H temperature grade meets your application's worst-case ambient. This page consolidates distributor pricing, drop-in alternatives, and practical design notes not found in the bare datasheet.

典型应用
PIC24HJ16GP304-H/PT 适用于 6 应用s: Automotive Body and Chassis Control, Industrial Motor Drive (Brushed DC, Stepper), Sensor Conditioning and Data Acquisition, Lighting and Human-Machine Interface, Point-of-Load and Power Conversion Control, Industrial Communication Gateway.
Automotive Body and Chassis Control
The PIC24HJ16GP304-H/PT fits automotive body and chassis controllers because its H temperature grade (up to +150C junction) covers underhood thermal stress, while the 40 MIPS core drives CAN/LIN gateways, mirror controllers, and seat-position loops. With 16 KB Flash and 2 KB SRAM the part runs a real-time scheduler plus a small OSEK-style task table; its 21 GPIO can sense multiple switch/wheel inputs and drive relays or half-bridges. Drop a hardware CRC engine on the CAN frame and the part handles end-to-end diagnostics natively. Engineers migrating to functional safety headroom can upgrade in-package to the PIC24HJ32GP204-H/PT without re-spinning the board.
推荐
Industrial Motor Drive (Brushed DC, Stepper)
For brushed DC and stepper motor drive loops the PIC24HJ16GP304-H/PT delivers a 16-bit core that executes PI/PID control at 40 MIPS, which is more than adequate for trapezoidal commutation at moderate PWM rates. The Enhanced CCP modules generate complementary PWM with programmable fault input, while the 10/12-bit ADC samples current shunts at high rate for closed-loop torque control. The 21 GPIO includes interrupt-on-change pins for Hall-effect sensors. For sinusoidal FOC, designers typically step up to a dsPIC33F variant in the same TQFP-44 footprint.
推荐
Sensor Conditioning and Data Acquisition
In multi-channel data acquisition the PIC24HJ16GP304-H/PT's 10/12-bit ADC and 21 GPIO make it a strong fit for thermocouple/bridge multiplexing, strain-gauge bridges, and 4-20 mA loop digitization at moderate sample rates. With 2 KB SRAM the part can buffer 8-channel scans at 1 kSPS without DMA, leaving the CPU free for linearization and Cold-Junction Compensation. The hardware CRC module enables reliable packetization of acquired data before transmission over UART/SPI, and the I2C peripheral allows digital sensor stacking behind a single interrupt line.
推荐
Lighting and Human-Machine Interface
The PIC24HJ16GP304-H/PT fits LED lighting and HMI panels because its 40 MIPS core can refresh small character/segment displays while driving PWM channels for LED dimming. The ECCP modules generate high-resolution PWM suitable for RGB color mixing, and the UART/SPI peripherals drive addressable LED strips or external shift-register key-scan matrices. Its automotive H grade supports interior/exterior lighting including headlamp leveling. For OLED displays, the SPI peripheral runs at the required 10 MHz+ rates without CPU overhead.
推荐
Point-of-Load and Power Conversion Control
In digital power conversion the PIC24HJ16GP304-H/PT acts as a digital controller for buck/boost and PFC converters, where 40 MIPS supports voltage-mode and average-current-mode loops with 100 kHz switching. The 10/12-bit ADC samples output voltage and current, the ECCP generates the switching PWMs with programmable dead-band, and the hardware CRC secures telemetry packets. The H grade thermal qualification is critical when the controller is co-located with power stages, and the 3.0-3.6 V VDD aligns with digital-isolated auxiliary rails.
推荐
Industrial Communication Gateway
For industrial communication gateways the PIC24HJ16GP304-H/PT bridges UART/RS-485, I2C, and SPI field devices with simple protocol translation, while running a small RTOS task loop or cooperative scheduler within 16 KB Flash. The hardware CRC engine is valuable for Modbus RTU/TCP and CANopen payload checks, and the 21 GPIO can bit-bang an additional RS-232 port or a parallel keypad interface. Drop-in upgrade to PIC24HJ32GP204-H/PT adds headroom for TLS-like handshake stubs on memory-constrained gateways.

设计说明
Place 10 uF bulk and 0.1 uF ceramic decoupling capacitors close to VDD and AVDD pins. According to the Microchip PIC24HJ16GP304 datasheet, AVDD and AVSS should be tied to the analog supply domain with an LC filter (10 ohm + 10 uF) to keep ADC noise below 1 LSB at 12-bit mode. Power-on ramp must complete within 50 ms to avoid BOR events in extended temperature.
Estimated: For a 4-layer PCB with a TQFP-44 (0.8 mm pitch), allocate 0.5 mm traces between TQFP pads and route ground on layer 2 with stitched via arrays every 4 mm. The exposed thermal pad is absent on TQFP-44, so heat is removed only through the perimeter pads; keep the part away from heat sources or rely on the H grade junction rating up to +150C.
Do not exceed 3.6 V on VDD or 5 V on any digital I/O. The PIC24HJ16GP304-H/PT is NOT 5V-tolerant on digital pins; use level shifters (e.g., MCP6001-based) when interfacing with 5V logic. Also, the MCLR pin must be tied to VDD through a 10 kΩ resistor and have a decoupling capacitor (0.1 uF) for clean power-on reset.
The Ethernet MII signals (ERXD0-1, ETXEN, ETXCLK, ERXCLK, ERXDV, ERXERR) on shared GPIO must be routed with 50 ohm characteristic impedance and matched trace lengths to avoid MII timing violations at 25 MHz. According to the Microchip PIC24HJ16GP304 datasheet, the analog functions (ETXEN, ERXDV) cannot be reassigned to other pins; if you do not use Ethernet, those pins revert to GPIO. Keep ETXCLK and ERXCLK traces length-matched within 5 mm.
