PIC24HJ256GP210T-I/PF 概述
A PIC24 microcontroller is a 16-bit MCU from Microchip's PIC24 family that uses a modified Harvard architecture with separate program and data buses, enabling single-cycle instruction prefetch and deterministic interrupt response. It sits within the broader hierarchy of microcontrollers (MCU -> 16-bit MCU -> PIC24 -> PIC24H high-performance), positioned above the 8-bit PIC16/PIC18 families and below the 32-bit PIC32 devices. The PIC24H subfamily is optimized for high-throughput DSP-adjacent applications without a full DSP engine.
Key features include 85 I/O pins, two UART modules, two SPI interfaces, two I2C peripherals, two Enhanced CAN 2.0B modules, one 16-bit timer and five 16-bit timers/counters, an input capture module, and a 10-bit/1.1 Msps A/D converter with up to 32 input channels. The device operates from 3.0 V to 3.6 V across an industrial -40C to +85C temperature range and supports in-circuit serial programming (ICSP) plus JTAG boundary scan.
Technically, the PIC24HJ256GP165 architecture provides a 24-bit instruction word with 16-bit data paths, 17 x 17-bit hardware multiplier, 32-bit barrel shifter, and zero-overhead hardware DO/REPEAT loops, delivering 40 MIPS at 80 MHz FOSC. The integrated DMA controller with up to 8 channels offloads peripheral transfers and frees the CPU for control logic.
Typical applications include industrial automation and motor control, data acquisition systems, communication gateways, building automation controllers, medical instrumentation, and automotive body/telematics ECUs. Designers typically choose this device when they need large Flash for protocol stacks plus CAN connectivity in a single chip.
When designing with this MCU, allocate a 100 nF decoupling capacitor near each power pin and a 10 uF bulk capacitor on the 3.3 V rail. The PIC24HJ256GP210 is a 3.3 V part; do not apply 5 V signals to any I/O. Always configure unused I/O as outputs to minimize power consumption.

典型应用
PIC24HJ256GP210T-I/PF 适用于 7 应用s: Industrial Motor Control, Industrial Data Acquisition Systems, Industrial Communication Gateways, Building Automation Controllers, Medical Instrumentation, Automotive Body and Telematics ECUs, Smart Energy and Power Metering.
Industrial Motor Control
The PIC24HJ256GP210T-I/PF is well suited to industrial motor control because its 40 MIPS throughput can execute field-oriented control (FOC) algorithms at 20 kHz PWM while leaving cycles for current-loop maths. Its 256 KB Flash holds sensorless FOC firmware plus CANopen stacks, and its 85 I/O pins drive multiple PWM channels, encoder feedback, and gate-driver signals. The 16-bit ADC with 1.1 Msps sampling rate handles phase-current sensing through simultaneous sampling, while dual Enhanced CAN modules handle command/feedback networking. Compared with the older PIC24FJ family, the PIC24H runs at double the MIPS at the same 80 MHz FOSC, giving designers headroom for advanced commutation schemes.
推荐
Industrial Data Acquisition Systems
Industrial data acquisition systems benefit from the PIC24HJ256GP210T-I/PF's 16 KB RAM and 256 KB Flash, which together can buffer multi-channel sensor streams and run real-time statistics (RMS, FFT-light, peak detection). Its 10-bit ADC with up to 32 input channels handles direct sensor interfacing at 1.1 Msps, while dual UART/SPI/I2C peripherals connect to displays, ADCs, and isolated digital I/O. The integrated DMA controller with up to 8 channels offloads sample transfers from the CPU, freeing MIPS for compression or protocol conversion. Compared with PIC24FJ64GB, this part adds 4x the Flash and 2x the RAM at the same 100-pin TQFP footprint.
推荐
Industrial Communication Gateways
The PIC24HJ256GP210T-I/PF integrates two Enhanced CAN 2.0B modules, two UART, two SPI, and two I2C peripherals in a single 100-pin TQFP package, making it ideal for industrial gateways that bridge CANopen or DeviceNet to Modbus-RTU, Ethernet, or Wi-Fi via external PHYs. Its 256 KB Flash holds full protocol stacks (CANopen, Modbus, J1939), while 16 KB RAM maintains frame buffers during peak load. The 40 MIPS throughput can service 1 Mbps CAN traffic without dropped messages. Compared with PIC18F devices, this PIC24H variant provides deterministic interrupt response needed for industrial control loops.
推荐
Building Automation Controllers
Building automation controllers (HVAC, lighting, access control) deploy the PIC24HJ256GP210T-I/PF because its 85 I/O pins drive relay banks, triac switches, keypads, and displays from one MCU. Its 256 KB Flash accommodates BACnet, Modbus, and proprietary automation stacks, while the 3.0 V to 3.6 V supply simplifies integration with 3.3 V sensors. The industrial -40C to +85C operating range covers unconditioned mechanical rooms. Compared with 8-bit PIC16 alternatives, this 16-bit MCU delivers 40 MIPS, so response latency stays under 10 ms even with multiple active communication stacks.
推荐
Medical Instrumentation
Medical instrumentation such as patient monitors, infusion pumps, and point-of-care analyzers benefit from the PIC24HJ256GP210T-I/PF's deterministic 16-bit architecture, which simplifies FDA design-history file documentation. Its 256 KB Flash accommodates safety firmware plus IEC 62304 class B self-test routines, while dual CAN interfaces isolate safety-critical busses. The 3.3 V operation reduces battery current in portable devices, and 85 I/O pins drive LCDs, keypads, and isolated sensor front-ends. Compared with PIC32 alternatives, this part offers lower cost while preserving the high performance needed for deterministic control loops.
推荐
Automotive Body and Telematics ECUs
Automotive body and telematics ECUs (BCM, gateway modules, instrument clusters) leverage the PIC24HJ256GP210T-I/PF's dual Enhanced CAN 2.0B modules and LIN support for in-vehicle networking. Its 256 KB Flash holds J1939 or CANopen stacks plus application logic, and its 16 KB RAM sustains concurrent CAN frame processing. The automotive temperature grade variant (PIC24HJ256GP210A-E/PF) extends operating range to -40C to +125C, qualifying it for under-hood applications. Compared with 8-bit PIC18 alternatives, this PIC24H provides 40 MIPS to service multiple CAN busses simultaneously.
推荐
Smart Energy and Power Metering
Smart energy and power metering applications use the PIC24HJ256GP210T-I/PF for accurate metrology on the 10-bit ADC and 16-bit DSP-adjacent math capabilities. Its 256 KB Flash stores DLMS/COSEM or IEC 62056 protocol stacks, while 16 KB RAM maintains measurement buffers. Dual UART/SPI/I2C peripherals connect to communication modules (PLC, RF, GSM) for AMI backhaul. The 3.0 V to 3.6 V supply range suits battery-backed metering. Compared with PIC24FJ256, this PIC24H variant offers the same Flash but higher 40 MIPS throughput to process metering math in real time.

设计说明
Place a 100 nF decoupling capacitor within 5 mm of each VDD/AVDD pin, plus a single 10 uF bulk capacitor on the 3.3 V rail close to the MCU. The PIC24HJ256GP210T-I/PF is a 3.3 V part; do not exceed 3.6 V on any VDD pin or apply 5 V signals to any I/O - use a level translator such as the MCP2551 or TXS0108E if your peripheral bus is 5 V. Keep the AVDD supply clean by adding a ferrite bead between VDD and AVDD to maximize ADC accuracy.
At -40C to +85C industrial temperature with full 40 MIPS throughput, junction temperature typically remains under 60C on the standard 100-pin TQFP (14x14) package. Thermal resistance theta_JA is approximately 38 C/W (per Microchip family datasheet). For continuous full-MIPS workloads in enclosed enclosures, use thermal vias under the exposed pad and 4-layer PCB copper pour to keep die below 100C; for harsh environments consider the -E/PF automotive variant rated -40C to +125C.
Use a 4-layer PCB with a dedicated ground plane for the 100-pin TQFP (14x14) footprint. Place the MCU near the center of the board to minimize trace lengths to peripherals; route the 80 MHz FOSC crystal traces symmetrically and within 10 mm of the OSC1/OSC2 pins. Keep JTAG/ICSP signals (TMS, TCK, TDI, TDO) short and away from switching power converters. Reserve space for a 2.4-pin (0.1 inch) ICSP header for in-circuit programming during prototype bring-up.
Avoid configuring unused I/O as inputs - floating inputs draw extra current and can trigger false interrupts. Configure all unused I/O as digital outputs driving low. Do not apply power before the MCU completes its internal oscillator stabilization period. When migrating firmware from PIC24FJ to PIC24H, note that the ADC configuration registers differ and the PIC24H ADC requires explicit sampling time setup; consult the family datasheet errata for silicon revision differences between the original GP210 and the newer GP210A.
For 1 Msps ADC sampling on the PIC24HJ256GP210T-I/PF, isolate analog signals from digital switching nodes by at least 25 mm of trace length and add a ground guard ring around analog input pins. Use a 4.7 nF anti-aliasing RC network at each analog input if the source impedance exceeds 5 kohm. For high-speed CAN at 1 Mbps, keep CANH/CANL traces differential with 100 ohm impedance and add a 120 ohm termination resistor at each bus end per ISO 11898.
合规信息
Industrial-grade PIC24HJ256GP210T-I/PF is RoHS/REACH compliant and lead-free per Microchip product documentation. For AEC-Q100 qualified automotive parts, choose PIC24HJ256GP210A-E/PF extended-temperature variant instead.
