PIC24HJ64GP204-E/PT Présentation
A 16-bit microcontroller (MCU) is a microprocessor-on-a-chip that integrates a 16-bit CPU core, program and data memory, peripherals, and I/O on a single die. The PIC24H family uses a modified Harvard RISC architecture with 16-bit wide data paths and a 24-bit instruction word, sitting in the hierarchy between 8-bit PIC MCUs and 32-bit MIPS-based PIC32 devices. The 40 MIPS performance class is typically applied to high-speed repetitive control loops, motor control, and digital signal preprocessing where 8-bit MCUs run out of headroom but a full DSP is unnecessary.
Key features include a 16-channel 10/12-bit ADC (configurable), three 16-bit timers (pairable to one 32-bit), two output compares, two UART/SPI/I2C capable EUSART/ECAN modules, a 4-channel DMA controller, an 8-bit parallel master port, and a charge time measurement unit (CTMU) for capacitive touch sensing. The automotive -E temperature grade and AEC-Q100 qualification make this variant a direct fit for under-hood and cabin electronic control units.
Architecturally, the PIC24HJ64GP204 implements a single-cycle hardware multiplier, a 16x16-bit working register array, and a 23-bit program counter. Code execution at 40 MHz completes most instructions in one cycle, giving deterministic interrupt latency suitable for hard-real-time control. The DMA controller offloads peripheral-to-memory transfers, freeing the core for control algorithms.
Typical applications include automotive body control modules, HVAC damper actuators, sensor interface hubs, industrial PLC I/O cards, BLDC motor control sensor interfaces, and consumer appliances with capacitive touch user interfaces. The 8 KB SRAM accommodates modest protocol stacks such as CAN and LIN.
When designing with this device, ensure the 3.0-3.6 V supply is tightly regulated, allocate a 4.7uF-10uF decoupling network near VDD/AVDD pairs, and reserve the MCLR pin for a proper reset supervisor. The E variant ships in 44-TQFP only, so verify your PCB land pattern matches.

Applications typiques
PIC24HJ64GP204-E/PT convient pour 6 applications: Automotive Body Control Modules, Industrial HVAC Damper Actuators, Sensor Interface Hubs with Capacitive Touch, PLC Digital I/O Modules, BLDC Motor Sensor Interface Boards, Medical Patient Monitoring Peripherals.
Automotive Body Control Modules
The PIC24HJ64GP204-E/PT suits automotive BCMs because its AEC-Q100 qualification and -40C to +125C 'E' temperature grade meet under-hood and cabin thermal stress while ECAN and LIN peripherals support multiplexed vehicle bus architectures. With 8 KB SRAM the part handles CAN/LIN protocol stacks comfortably, and 40 MIPS gives enough headroom for body control algorithms like central locking, lighting sequencing, and wiper control loops. Pair with MCP2551 CAN transceivers for the bus physical layer. The 16-channel 12-bit ADC interfaces directly with automotive sensor dividers (temperature, battery voltage, switch position) without external signal conditioning.
Recommandé
Industrial HVAC Damper Actuators
In HVAC damper and valve actuators the PIC24HJ64GP204-E/PT drives BLDC or stepper motors while reading position feedback through its 12-bit ADC. The 40 MIPS throughput executes PI/PID control loops at 10 kHz, exceeding typical damper bandwidth by 100x. Its DMA controller offloads encoder counting to keep CPU load low, and the 4 KB of SRAM accommodates small RTOS kernels for multi-axis coordination. The 44-TQFP package fits inside compact actuator housings, and the wide 3.0-3.6 V supply tolerates rectified 24 VAC industrial rails after a buck regulator.
Recommandé
Sensor Interface Hubs with Capacitive Touch
The PIC24HJ64GP204-E/PT's on-chip Charge Time Measurement Unit (CTMU) enables up to 16 capacitive touch buttons without external touch ICs, ideal for appliance user interfaces. The 12-bit ADC provides 0.5 mV resolution on 3.3 V analog sensors, while the CTMU timing hardware measures capacitance changes at microsecond rates. With 64 KB Flash the device stores both touch firmware and communication stacks. Pair the CTMU with PCB pad sensors and overlay materials of 1-3 mm thickness for reliable touch detection in kitchens or industrial panels.
Recommandé
PLC Digital I/O Modules
Modular PLC digital input/output modules benefit from the PIC24HJ64GP204-E/PT's 21 I/O pins, ECAN interface for backplane communication, and 40 MIPS throughput for fast debounce and timing logic. The 4-channel DMA engine scans inputs in parallel with control logic execution, while 8 KB SRAM buffers event logs between CAN transmissions. The -40C to +125C temperature range survives control cabinet environments, and the 44-TQFP package mounts on standard DIN-rail backplane PCBs.
Recommandé
BLDC Motor Sensor Interface Boards
For BLDC motor control sensor interface boards, the PIC24HJ64GP204-E/PT reads three Hall-effect or back-EMF signals through its high-speed ADC and timers, then forwards rotor position to a main motor controller via SPI. The 40 MIPS performance processes 60 kHz PWM-aligned feedback with sub-microsecond jitter, while DMA captures timer values without CPU intervention. Its compact 44-TQFP footprint fits inside motor housings, and the wide supply range survives inverter-induced voltage transients when paired with TVS protection.
Recommandé
Medical Patient Monitoring Peripherals
The PIC24HJ64GP204-E/PT can serve as a peripheral controller in patient monitoring subsystems, handling display driving, button input, and battery management. Its 12-bit ADC reads battery voltage, temperature, and analog sensor signals with 0.5 mV resolution, while ECAN communicates with the main processor board. The DMA engine offloads display buffer updates, freeing the core for user interface logic. While not a primary life-critical MCU, it fits auxiliary roles in IEC 60601-1 compliant systems when paired with appropriate isolation.

Principaux différenciateurs
- Automotive AEC-Q100 qualification across full -40C to +125C temperature range (vs PIC24HJ64GP204-I/PT)
- 64 KB Flash with 40 MIPS core balances code density and compute throughput (vs PIC24FJ64GA204-E/PT)
- Hardware DMA controller offloads peripheral-to-memory transfers (vs PIC24HJ32GP204-E/PT)
Notes de conception
Estimated: at 40 MHz CPU activity and all peripherals enabled, the PIC24HJ64GP204-E/PT draws roughly 50-70 mA from the 3.3 V supply. Place a 4.7uF bulk capacitor plus a 100 nF decoupling capacitor within 5 mm of VDD (pin 33) and VSS (pin 34). Add separate 100 nF capacitors on AVDD (pin 22) and AVSS (pin 21) to keep analog measurements clean. Avoid routing high-frequency digital signals across the analog supply plane to minimize ADC noise injection.
At -40C to +125C operation the silicon junction can reach 150C with 25C margin to the absolute maximum. The 44-TQFP has a theta_JA of approximately 50 C/W on a 4-layer JEDEC test board. With 50 mA at 3.3 V (165 mW dissipation), junction rise is only about 8C, leaving >100C thermal headroom. For applications mounting the part on small PCBs with limited copper, consider adding thermal vias under the exposed pad (if used) or upgrade to the -H grade for higher temperature margin.
Keep the MCLR pin (pin 14) properly pulled up to VDD via a 10 kohm resistor and a 100 nF capacitor for noise immunity. The ICSP/PGEDx/PGECx pins (15-18) must be accessible on the PCB for in-circuit programming - never connect these pins directly to ground or VDD. Reserve a small trace stub for the ICSP header even in production designs to allow field firmware updates. Place the crystal or external clock source within 10 mm of OSC1/OSC2 (pins 12/13) with a ground guard ring to reduce EMI.
Do not confuse the -E (automotive, -40C to +125C) suffix with -I (industrial, -40C to +85C) - parts look identical but differ in qualification testing and temperature grade. The 'T' suffix in PIC24HJ64GP204T-E/PT only indicates tape-and-reel packaging, not different silicon. The 44-TQFP and 44-QFN packages are NOT pin-compatible because the QFN pinout reassigns some peripheral pins; verify land pattern before substituting. Finally, always configure unused I/O pins as outputs driven low to minimize power consumption and reduce EMI susceptibility.
