MPN： PIC24HJ64GP206AT-I/MR ✓ 啟用中PIC24HJ64GP206AT-I/MR 概覽
Key specifications include a 40 MHz maximum operating frequency (yielding 40 MIPS), 64 KB on-chip Flash program memory, 8 KB SRAM, 4 KB EEPROM emulation data memory, and a wide operating voltage range of 3.0V to 3.6V. The device features advanced peripherals including 2 UART, 2 SPI, and 2 I2C interfaces, plus a 16-channel 10/12-bit ADC. It also integrates a 16-bit timer/counter block and up to 51 general-purpose I/O pins. The 'A' suffix indicates revision A silicon; the trailing 'T' indicates tape-and-reel packaging; the '-I' industrial temperature range is -40C to +85C.
A 16-bit MCU is a microcontroller built around a 16-bit data path and instruction word, offering higher code density and arithmetic throughput than 8-bit MCUs while retaining deterministic real-time interrupt behaviour. Within Microchip's hierarchy, the PIC24H belongs to the PIC24F/PIC24H family of 16-bit microcontrollers -> PIC24 microcontroller family -> 16-bit MCU class -> embedded microcontroller -> semiconductor. The PIC24H architecture shares a 16-bit modified Harvard core with the dsPIC33F DSC family, enabling migration to DSP functionality with the same tool chain and peripheral set.
The 'GP' (General Purpose) part number denotes a peripheral mix tuned for control loops, communication bridging, and human-machine interface tasks. The PIC24HJ64GP206A devices are pin-compatible with the dsPIC33FJ64GP206A DSC family, allowing firmware upgrade paths from MCU to DSC with the same PCB footprint. The 64-VQFN exposed pad package provides low thermal resistance for reliable operation in industrial environments with junction temperatures up to 150C.
Typical applications include industrial motor control, sensor signal processing, switching power supply digital control, USB device controllers (with external PHY), HVAC controllers, and automotive body electronics sub-modules. The 40 MIPS throughput makes it well-suited for real-time PID loops and digital filtering tasks where an 8-bit MCU would saturate the CPU.
When designing with this part, ensure the VQFN exposed pad is soldered to a sufficient copper pour (recommended 1 square inch minimum) for thermal dissipation. Decoupling capacitors (100 nF + 10 uF bulk) must be located within 5 mm of each power pin to meet the ADC SNR spec. For designs migrating to DSP, use the pin-compatible dsPIC33FJ64GP206A directly without PCB rework.

典型應用
PIC24HJ64GP206AT-I/MR 適用於 7 應用s: Industrial Motor Control, Digital Switching Power Supply Control, Industrial Sensor Hub and Modbus Gateway, HVAC Variable Frequency Drive Controller, Automotive Body Electronics Sub-Module, Medical Patient Monitoring Sub-System, Building Automation Lighting Controller.
Industrial Motor Control
The PIC24HJ64GP206AT-I/MR is well suited for sensor-based BLDC and PMSM motor control applications requiring deterministic real-time response. Its 40 MIPS throughput handles PI velocity loops running at 20 kHz update rates with substantial code headroom for trapezoidal commutation tables. The 16-channel 10/12-bit ADC reads back EMF sensing comparators and Hall-effect sensors simultaneously with 1 MSPS aggregate sample rate, while dual PWM channels (one per motor phase pair) drive 3-phase inverter MOSFETs via isolated gate drivers. Pair the MCU with a 3-phase gate driver such as the MCP8024 or FAN7884. Compared to a dsPIC33F DSP, the PIC24H loses the single-cycle MAC engine for field-oriented control (FOC) - choose dsPIC33FJ64GP206A-I/MR for sensorless FOC, otherwise the PIC24HJ64GP206A is the cost-optimal MCU for sensored commutation and trapezoidal control. The 64-VQFN exposed pad allows sustained junction temperature rise below 50C at 1 W dissipation.
推薦
Digital Switching Power Supply Control
The PIC24HJ64GP206AT-I/MR serves as a digital controller for isolated and non-isolated switching power supplies including PFC stages, half-bridge converters, and full-bridge topologies. Its 40 MIPS throughput handles digital average current-mode control loops running at 100 kHz switching frequency with 1.5 MIPS CPU budget per switching period, plus auxiliary housekeeping tasks. The 12-bit ADC (configurable to 10-bit for higher speed) samples current-sense and voltage-feedback signals at up to 500 kSPS, while dedicated PWM channels with 7.5 ns resolution drive synchronous rectifier MOSFETs. The 8 KB SRAM accommodates state-variable tables for up to 4 closed-loop control variables. Compared to an 8-bit PIC16 MCU, the PIC24HJ64GP206A executes the digital compensation filter with 2.5x headroom, enabling adaptive digital compensation. Use this MCU in 100 W to 1 kW telecom/datacenter PSU sub-modules where deterministic interrupt response prevents catastrophic MOSFET cross-conduction events.
推薦
Industrial Sensor Hub and Modbus Gateway
The PIC24HJ64GP206AT-I/MR functions as an industrial sensor hub aggregating analog/digital sensor inputs and forwarding them via Modbus RTU or Modbus TCP to a PLC or SCADA system. Its 16-channel ADC and 51 GPIO pins interface to 4-20 mA current-loop sensors, RTDs, thermocouples (via external PGA), and discrete digital inputs. The two UART ports handle the RS-485 Modbus master/slave port and a configuration/diagnostic port simultaneously, while the dual SPI/I2C blocks connect to digital temperature sensors, EEPROM, and external ADC for higher-precision channels. The 40 MIPS throughput runs the Modbus RTU state machine, polynomial CRC-16 verification, and HMI-side polling logic with negligible CPU loading. Compared to a Cortex-M0+ alternative, the PIC24H's deterministic interrupt latency is preferable in industrial environments with frequent sub-millisecond sensor updates.
推薦
HVAC Variable Frequency Drive Controller
The PIC24HJ64GP206AT-I/MR drives a variable-frequency compressor motor in residential and light-commercial HVAC systems. Its 40 MIPS throughput handles sinusoidal commutation algorithms and torque-ripple compensation at PWM frequencies up to 20 kHz, while the 16-channel ADC monitors DC bus voltage, phase currents, IPM temperature, and PFC input waveforms simultaneously. The two I2C blocks interface to EEPROM (setpoint storage), digital temperature sensors, and external RTC modules for time-of-use scheduling. The dual UART ports connect to the Wi-Fi/BLE HVAC module and to the service technician diagnostic port. Compared to a dsPIC33F DSC, the PIC24HJ64GP206A is the cost-optimized choice for fixed-frequency V/Hz control and basic sensorless trapezoidal commutation, whereas dsPIC33FJ64GP206A is required for full sensorless FOC with high starting torque.
推薦
Automotive Body Electronics Sub-Module
Although not AEC-Q100 qualified, the PIC24HJ64GP206AT-I/MR is used in non-safety automotive body electronics sub-modules including HVAC blowers, seat controllers, and accessory modules in passenger vehicles. The -40C to +85C industrial temperature range tolerates cabin temperatures, and the 40 MIPS throughput drives LIN or CAN sub-bus nodes for body control. Note the part is not AEC-Q100 qualified; for AEC-Q100 designs, Microchip offers the dsPIC33FJ64GP206A AEC-Q100 qualified variants. The 64 KB Flash accommodates OBD-II diagnostic handlers and CAN/LIN stack layers. The 8 KB SRAM supports up to 8 simultaneous message buffers. For under-the-hood applications exceeding +85C, Microchip recommends AEC-Q100 qualified dsPIC33CH/dsPIC33CK dual-core parts.
推薦
Medical Patient Monitoring Sub-System
The PIC24HJ64GP206AT-I/MR is suitable for medical patient monitoring sub-systems including bedside monitor IO modules, pulse oximetry front-ends, and infusion pump control. Its 40 MIPS throughput runs digital filtering on PPG/bio-impedance signals, while the 12-bit ADC captures low-amplitude sensor outputs with adequate SNR for SpO2 calculation. The dual UART ports connect to bedside display modules and to the central station telemetry link. The 64 KB Flash accommodates IEC 62304 lifecycle documentation templates and DSP filter coefficients. Compared to an 8-bit PIC MCU, the PIC24HJ64GP206A executes a 100-tap FIR filter with 8x lower CPU loading. For IEC 60601-1-8 compliant alarm subsystems, an additional supervisory MCU is recommended since the PIC24H lacks the SIL3 diagnostic coverage required for primary alarm paths.
推薦
Building Automation Lighting Controller
The PIC24HJ64GP206AT-I/MR serves as a DALI-2 or DMX512 lighting controller in commercial building automation systems. Its 40 MIPS throughput runs the DALI-2 application controller stack including color-temperature (Tunable White) calculations, while the dual UART ports handle the DALI bus master interface and the RS-485 BACnet/Modbus trunk. The 16-channel ADC reads ambient light sensors and occupancy detectors, while the PWM channels drive LED driver enable inputs. The 8 KB SRAM supports scene storage tables for up to 16 lighting presets. Compared to a Cortex-M0+ alternative, the PIC24H's deterministic interrupt latency is preferable in DMX512 packet-handling timing-critical tasks. For wireless lighting control via BLE/Zigbee, add an external nRF52832 or JN5168 module connected via SPI.

主要差異化特點
- Pin-compatible with dsPIC33F DSC family for firmware upgrade path (對比PIC24HJ64GP206A-I/PT)
- 40 MIPS throughput for real-time control loops (對比PIC24FJ64GA006-I/MR)
- Industrial temperature range for harsh environments (對比PIC24FJ64GB002-I/ML)
設計說明
The 64-pin VQFN (MR) package requires the exposed pad (EP, pin 64) to be soldered to a continuous ground copper pour on the top PCB layer, with thermal vias (recommended 9 vias in a 3x3 grid, 0.3 mm drill, 0.5 mm pitch) connecting to the internal ground plane. Without proper EP soldering, the thermal resistance theta_JA increases from ~28 C/W to ~70 C/W, causing the junction temperature to rise dramatically under load. The exposed pad must NOT be left floating - per JEDEC JESD51, it serves both thermal and electrical ground functions. Estimated: at 1 W dissipation, junction rise drops from ~70 C (un-soldered) to ~28 C (proper EP soldering).
Place a 10 uF X5R/X7R bulk decoupling capacitor and a 100 nF ceramic capacitor within 5 mm of each VDD pin pair (pins 16/17, 29/30, 56/57). The AVDD/AVSS analog supply pair (pins 36/37) requires a separate ferrite bead or LC filter from the digital VDD supply to achieve the ADC SNR spec of 60 dB. Estimated: 1 ohm ferrite bead + 10 uF + 100 nF gives a 40 dB noise attenuation at 50 MHz switching harmonics. Without proper AVDD filtering, the ADC exhibits 2-3 LSB noise and degrades sensor measurement accuracy.
The 16-channel ADC samples sequentially with a 1 MSPS aggregate rate; ensure analog source impedance is below 2.5 kohm to avoid ADC sample-capacitor settling errors. Add an external op-amp buffer (e.g., MCP6021) for high-impedance sensors like thermocouples or pH probes. For 4-20 mA current-loop inputs, use a 250 ohm precision sense resistor (0.1% tolerance) with Kelvin connection to the ADC pin. The ADC reference voltage (VREF+/VREF-) should be driven by an external 3.0V reference (e.g., MCP1525) for absolute measurement accuracy better than 1%.
Common pitfalls when designing with this MCU: (1) Forgetting to configure the JTAGEN bit in the FSEC register, which disables JTAG and locks out debug access; (2) Using the internal 7.5 MHz FRC oscillator for UART communications without enabling the PLL - baud rate error exceeds 2% causing framing errors; (3) Driving 5V signals directly to GPIO pins which are NOT 5V-tolerant - use a level translator like MCP1541 or DT3302; (4) Storing variables that exceed 32 KB into RAM without configuring the data EEPROM emulation library - causes silent data corruption in long-running applications.
