PIC24HJ128GP306A-E/PT Visão geral
What is a PIC24H microcontroller? The PIC24H is a 16-bit MCU family from Microchip Technology, positioned within the broader PIC24F/PIC24H/dsPIC33F product hierarchy as a high-performance general-purpose 16-bit controller. It uses a modified Harvard architecture with a 16-bit data path and 24-bit instruction word, sitting between the lower-cost PIC24F and the DSP-capable dsPIC33F families. It belongs to the wider category of microcontrollers (MCU) within the integrated circuits and embedded systems ecosystem.
Key features of the PIC24HJ128GP306A-E/PT include 128 KB Flash, 16 KB RAM, 53 programmable I/O lines, multiple 16-bit timers, DMA channels for CPU-offloaded data movement, and communication peripherals such as UART, SPI, and I2C. The device operates from 3.0 V to 3.6 V, supports -40C to +125C automotive-grade temperature range, and includes 10-bit and 12-bit ADC modules for mixed-signal acquisition. The -E suffix designates the extended (-40C to +125C) temperature grade, and /PT designates the 64-pin TQFP package.
The architecture uses a 5-stage pipeline with single-cycle multiply, enabling 40 MIPS throughput at 40 MHz. The PIC24H family shares a very high degree of pin compatibility with the dsPIC33F family, allowing easy migration when DSP extensions are required. The integrated DMA engine supports parallel data transfer between peripherals and memory without CPU intervention, freeing CPU cycles for control-loop and communication tasks.
Typical applications include industrial control systems, motor control (with companion dsPIC33F for FOC), automotive body and chassis ECUs, building automation, sensor interfacing, and consumer embedded products that need more performance than 8-bit MCUs but do not require full DSP capability. The 64-pin TQFP package also suits hand-solderable prototypes and low-volume production.
When designing with this part, pay attention to the 3.3 V supply requirement and decoupling near each VDD/VSS pair. Use the in-circuit serial programming (ICSP) interface for firmware updates, and verify the trace length on high-speed communication lines. This page synthesizes distributor pricing, drop-in alternatives from the PIC24H/dsPIC33F family, and practical design notes not found in the manufacturer datasheet.

Notas de projeto
Place one 10 uF tantalum or ceramic bulk capacitor near the main VDD pin and one 0.1 uF ceramic decoupling capacitor within 3 mm of every VDD/VSS pair. The PIC24HJ128GP306A-E/PT has multiple VDD/VSS pairs - decoupling each pair separately is mandatory for clean ADC readings. Use a separate low-noise LDO for AVDD if analog accuracy is critical. Estimated: total decoupling budget is approximately 6x 0.1 uF and 2x 10 uF for a typical 64-pin TQFP design.
Route the ICSP pins PGEDx/PGECx directly to a 6-pin header with no series resistors or capacitors in the path - these signals must reach the programmer at full logic levels. Place the crystal within 5 mm of OSC1/OSC2 and surround the traces with a ground pour to minimize EMI coupling. Avoid routing high-speed digital signals under the analog AVDD/AVSS pins to prevent digital noise from coupling into ADC measurements.
The 64-pin TQFP package has a typical theta_JA of approximately 45 C/W. At 40 MHz with all peripherals active the device draws around 60-80 mA, dissipating roughly 200-265 mW. At -E grade (125C max junction) this gives safe operation up to approximately 114C ambient. For high-temperature automotive environments near 125C, ensure the PCB copper area under the exposed pad or thermal vias exceeds 1 square inch.
Do not leave the MCLR pin floating - it must be pulled up to VDD through a 10 kohm resistor, with a 100 nF capacitor to ground for noise filtering (only if the in-circuit programmer allows). Always configure unused I/O pins as outputs driving low (not inputs) to minimize current draw in sleep mode. The Peripheral Pin Select feature requires explicit configuration before peripheral use; firmware that skips PPS init will appear to work in simulation but fail on hardware.
When using the parallel master port (PMP) or high-speed SPI at 10 MHz+ clock rates, add 22-33 ohm series termination resistors near the source pins to dampen reflections on long traces. For CAN bus designs, keep the CANH/CANL differential pair length-matched within 5 mm and twist them at 1 turn per 25 mm. The PIC24HJ128GP306A-E/PT is not 5 V tolerant on digital I/O - never connect directly to 5 V logic without a level translator.
