PIC24HJ64GP502-E/SO - 16-bit 40 MIPS MCU, 64KB Flash, 28-SOIC | Microchip
MPN: PIC24HJ64GP502-E/SO ✓ Hoạt độngPIC24HJ64GP502-E/SO Tóm tắt
A 16-bit microcontroller (MCU) is a microprocessor-on-chip that combines a CPU core, program memory, data memory and on-chip peripherals behind a single package boundary. The PIC24H architecture extends the original PIC 16-bit instruction set with a 16-bit data path and a single-cycle multiplier, placing it in the middle of the embedded performance spectrum between 8-bit MCUs (e.g. PIC16) and 32-bit ARM Cortex-M parts. The PIC24HJ64GP502-E/SO is functionally part of the broader PIC24F/PIC24H/PIC24FJ family and is pin-compatible with the dsPIC33F DSC family, which adds a DSP engine to the same core.
Key features include 40 MIPS CPU performance (one instruction per clock cycle from the 40 MHz oscillator), 64 KB Flash / 8 KB RAM, 16-channel 12-bit ADC with 500 ksps conversion rate, two UART modules with IrDA support, two SPI ports, one I2C port, a CAN 2.0B module, an 8-channel DMA controller for low-overhead data movement, and nanoWatt power management with multiple idle/sleep modes. The part supports in-circuit serial programming (ICSP) and in-circuit debugging via two dedicated pins.
Typical applications include automotive body and chassis ECUs (AEC-Q100 qualified), industrial motor control, sensor signal conditioning, CAN nodes on vehicle networks, and consumer appliance controllers where the combination of 16-bit performance, CAN, ADC and DMA simplifies the bill of materials.
When designing with this part, budget for a 3.3 V LDO with adequate transient response for the 40 MIPS core and reserve pin 1 (MCLR) for proper reset decoupling. The pin-compatible dsPIC33F family is a useful migration path if DSP throughput is later required.

Ứng dụng tiêu biểu
PIC24HJ64GP502-E/SO phù hợp cho 6 Áp dụngs: Automotive Body Control Modules, Industrial Motor Control (BLDC / Stepper), CAN-Enabled Sensor Nodes, Consumer Appliance Control Boards, Medical Monitoring Devices (Non-Implantable), Building Automation and HVAC Nodes.
Automotive Body Control Modules
The PIC24HJ64GP502-E/SO is well matched to body control modules such as lighting, mirror, seat and climate nodes because it integrates CAN 2.0B, a 12-bit ADC and PWM timers in a 28-SOIC footprint. AEC-Q100 qualification and the -40 C to +125 C enhanced automotive temperature grade let it sit behind the dashboard or in an engine-adjacent enclosure without thermal derating. The 40 MIPS core handles a J1939 stack plus application logic with headroom, while the 64 KB Flash stores protocol code, calibration tables and bootloaders. Typical placement is the CAN transceiver on the bus side and a 3.3 V LDO on the supply side; the MCU's DMA keeps the ADC-to-CAN path running without CPU intervention.

Industrial Motor Control (BLDC / Stepper)
The PIC24HJ64GP502-E/SO suits small industrial motor drives that need deterministic 16-bit timing: its three 16-bit timers can be paired into a 32-bit timer for high-resolution PWM generation, and the 40 MIPS throughput handles field-oriented control loops at typical 10-20 kHz switching frequencies. The 12-bit ADC with 500 ksps supports current and back-EMF sensing, while CAN enables networked multi-axis systems. Designers typically route PWM to a three-phase gate driver such as the MCP8024, with the MCU sitting on a 3.3 V LDO; the SOIC-28 package provides enough thermal margin at moderate PWM duty cycles without a heatsink.

CAN-Enabled Sensor Nodes
Distributed sensor nodes in industrial automation and chassis systems benefit from the PIC24HJ64GP502-E/SO's combination of CAN 2.0B, 12-bit ADC and DMA. With 8 KB RAM and 40 MIPS, the device can buffer incoming CAN frames while digitizing analog inputs at up to 500 ksps without dropping messages. The 28-SOIC footprint supports compact sensor housings, and the AEC-Q100 grade lets the same firmware run in both cab-mounted and under-hood locations. Typical placement pairs the MCU's CAN module with a high-speed transceiver like the MCP2551, with the analog signal conditioned through an op-amp such as the MCP6002 before the ADC input.
Được đề xuất
Consumer Appliance Control Boards
The PIC24HJ64GP502-E/SO fits mid-range consumer appliances such as washing machines, dishwashers and HVAC controls where a 16-bit MCU drives an HMI and a motor or valve network. The 64 KB Flash stores user-interface code plus motor algorithms, while the two UARTs interface to HMI displays and the two SPI ports connect to EEPROM or sensor ICs. AEC-Q100 qualification provides reliability margin even in non-automotive environments, and the wide-SOIC package eases hand-soldering and rework in low-volume SKUs. Power the MCU from a 3.3 V LDO downstream of a small switching pre-regulator; the nanoWatt idle modes drop Iq to a few microamps for standby energy compliance.

Medical Monitoring Devices (Non-Implantable)
For non-implantable medical monitoring equipment such as blood-pressure cuffs, pulse oximeters and portable infusion monitors, the PIC24HJ64GP502-E/SO delivers 40 MIPS performance and 12-bit ADC accuracy in a small, easy-to-assemble SOIC-28 package. The AEC-Q100 temperature grade covers clinical environment thermal stress, while the integrated DMA offloads sensor data movement so the CPU can run foreground safety checks. Designers typically pair the MCU with a precision op-amp like the MCP6002 for sensor signal chains, with results shown on a UART/SPI-driven LCD. The 8 KB RAM accommodates circular buffers for 1 ksps streaming while the CAN/UART ports feed host equipment.
Được đề xuất
Building Automation and HVAC Nodes
The PIC24HJ64GP502-E/SO is well suited to building-automation I/O nodes (lighting panels, VAV controllers, fan-coil units) where CAN or RS-485 networking, 12-bit analog measurement and PWM outputs drive actuators. The 21 GPIO pins expose enough parallel I/O for a typical VAV box, while the two UART ports support RS-485 transceivers for BACnet or Modbus links. The industrial-grade -40 C to +85 C variants cover indoor equipment closets, and AEC-Q100 adds margin for rooftop or plant-room environments. The 28-SOIC package eases field serviceability, with firmware updates delivered over ICSP using the dedicated programming pins.

Ghi chú thiết kế
Power the PIC24HJ64GP502-E/SO from a 3.3 V LDO with at least 100 mA headroom and 50 mV peak-to-peak transient tolerance. The internal core LDO derived from VDD requires a 10 uF ceramic decoupling capacitor on the VCAP pin (pin 13) placed within 0.25 inch of the pin. Brown-out reset must be enabled in configuration bits to avoid Flash corruption on slow power-down. For automotive environments, add a TVS diode on VDD and a series ferrite to suppress load-dump transients.
Route the ICSP signals PGED1/PGEC1 and PGED2/PGEC2 (pins 16/17 and 4/5) to an accessible programming header or test pad without series resistors in the path. Keep the 28-SOIC Wide footprint on top layer with a continuous ground pour under the part to keep digital return paths short. Crystal traces on pins 9-10 (OSC1/OSC2) should be short, surrounded by ground, and kept away from switching nodes to avoid jitter. Place the CAN signals C1RX/C1TX (pins 14/15) close to the transceiver and add a 4.7 nF split-termination capacitor at the bus end per CAN 2.0B ISO 11898 recommendations.
Estimated: programming the configuration bits is mandatory - a missing _FOSC selection (e.g. choosing HS oscillator without enabling the PLL block) will leave the device at 4 MHz instead of 40 MIPS and drop throughput 10x. The MCLR pin (1) requires a 10 kohm pull-up to VDD and a 100 nF cap to ground for clean reset; an unbypassed MCLR causes intermittent brown-out resets in noisy environments. Do not exceed 3.6 V on any pin - the absolute maximum is 4.0 V and AEC-Q100 stresses push margin. Finally, disable the JTAG pins in configuration bits if unused - leaving them as GPIO can cause unexpected current spikes during reset.
