PIC24HJ128GP504-I/PT - 16-bit MCU 128KB Flash 40MIPS | Microchip
MPN: PIC24HJ128GP504-I/PT ✓ Hoạt độngPIC24HJ128GP504-I/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals into one IC. The PIC24H family uses a 16-bit modified Harvard RISC architecture with 24-bit instructions, optimized for code density and deterministic real-time control. Within Microchip's portfolio, PIC24H sits between the 8-bit PIC18 family and the 32-bit PIC32MX/dsPIC33E families, delivering high-performance 16-bit DSP capability for motor control, digital power, and audio processing applications.
The PIC24HJ128GP504 integrates 128 KB Flash (43K x 24 words), 8 KB SRAM, 4 KB EEPROM emulation in Flash, two UART/SPI/I2C modules, two CAN modules, an Enhanced 16-bit Parallel Master Port, a 12-bit ADC with up to 13 input channels and 500 ksps conversion rate, and a 16-bit timer/capture/compare/PWM module set. The device is pin-compatible with the dsPIC33F family, allowing migration to a DSP-enhanced core without PCB changes.
Architecturally, the PIC24HJ128GP504 uses a 2-stage pipeline with a hardware multiplier and 16x16-bit single-cycle MAC, enabling efficient fixed-point DSP operations. Its DMA controller supports memory-to-peripheral transfers without CPU intervention, and its Peripheral Pin Select (PPS) feature allows flexible remapping of digital peripherals to I/O pins - a significant advantage over PIC24F parts that lack this capability.
Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion (PFC, LLC, full-bridge converters), automotive body and sensor interfaces, medical instrumentation, and high-reliability industrial automation. The combination of CAN, UART, SPI, I2C, and 12-bit ADC peripherals makes the part well suited as a system supervisor in distributed embedded networks.
When designing with the PIC24HJ128GP504, ensure the 3.3V supply rail is well decoupled with at least 10uF + 100nF local capacitance, and that any analog reference for the 12-bit ADC uses a low-noise LDO such as the MCP1700. Programming and debugging should use Microchip's MPLAB X IDE with a PICkit 4 or ICD 4 in-circuit debugger.

Ghi chú thiết kế
Decouple the PIC24HJ128GP504-I/PT's VDD pins (7, 28) with a 100 nF ceramic capacitor placed within 3 mm of each VDD pin, plus a bulk 10 uF tantalum or ceramic capacitor on the 3.3V rail. Use a low-noise LDO such as MCP1700-3302E to derive the 3.3V supply from a 5V rail, providing >40 dB noise rejection at 1 kHz to keep the ADC reference clean.
Do not apply 5V to any PIC24HJ128GP504-I/PT I/O pin; this device is NOT 5V-tolerant. A common production pitfall is reusing PIC18 8-bit code with 5V logic levels - this destroys the PIC24H. If 5V signals are present, add a 74LVC245 level translator or use the pin-compatible PIC24FJ parts with 5V tolerance.
Route the 80 MHz crystal traces (OSC1/OSC2) as short as possible and symmetric, with the load capacitors (typically 18-22 pF) placed within 5 mm of the MCU. Keep digital signal traces away from the analog ADC inputs (AN0-AN13) and use a ground guard ring around the AVSS pin to minimize digital switching noise coupling into ADC measurements.
When using the ECAN modules at 1 Mbit/s, place a 120 ohm termination resistor at each end of the CAN bus, twisted-pair cable between nodes, and keep the CANH/CANL traces matched in length (delta < 5 mm) on the PCB. Add a TVS diode (such as PESD1CAN) on the bus for ESD and transient protection in industrial environments.
