PIC24HJ32GP302T-I/MM 개요
A 16-bit microcontroller (MCU) is an integrated processor core that executes arithmetic and logical operations on 16-bit-wide data paths, occupying a middle tier in the embedded hierarchy: 16-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. PIC24H devices employ a modified Harvard architecture with a 16-bit data path and 24-bit instruction word, optimized for DSP-style computation loops and high-speed control applications. PIC24H IS also known as "dsPIC33F compatible" because the family shares pin compatibility with dsPIC33F MCUs and CISC architecture.
Key specifications of the device include 21 general-purpose digital I/Os, three 16-bit timers/counters (which can be paired to form one 32-bit timer), two output capture modules, and two UART modules. The following features distinguish it: an integrated 10/12-bit ADC with up to 500 ksps throughput, hardware multiplier for DSP operations, and dual comparator modules. The industrial-grade -I temperature range and 28-QFN compact footprint enable space-constrained industrial designs.
The architecture is a 16-bit PIC core with hardware multiply/divide and DSP extensions, supporting C-compiler-efficient instruction set. The high 40 MIPS throughput enables real-time DSP and motor control run-natives, while dual 16-bit timers provide precision event timing. The 28-QFN package includes an exposed thermal pad (EP) for low-theta-JA operation. Power-saving modes include Idle, Sleep, and Doze modes with multiple clock sources (HS, XT, EC, internal FRC).
Typical applications include industrial motor control (BLDC/PMSM), digital power conversion, sensor signal conditioning, and embedded control loops. The wide peripheral set also suits medical HVAC, RFID build, and consumer audio build systems.
When designing with this device, ensure the 3.3V rail is clean with at least 10uF bulk decoupling plus 0.1uF ceramic at each VDD pin. Use the exposed pad (EP) for thermal relief and connect it to ground with multiple thermal vias to maximize power dissipation capability.

설계 노트
Place a 10uF bulk decoupling capacitor near the VDD pin plus a 0.1uF ceramic capacitor as close to the VDD/VSS pair as the PCB layout allows (within 3 mm). For the 28-QFN-S package, route VDD and VSS on adjacent pins to minimize inductance. According to Microchip PIC24H design notes, inadequate decoupling causes Flash programming failures and erratic ADC readings. A ferrite bead between the analog AVDD and digital VDD rails is recommended for ADC accuracy below 12-bit noise floors.
The 28-QFN-S package has an exposed thermal pad (EP, pin 28 in our pinout table) that MUST be soldered to a grounded copper pour of at least 25 mm^2 with multiple thermal vias (8+ vias, 0.3 mm drill) for proper heat dissipation. Without EP soldering, junction temperature can rise 30-40C above ambient at full CPU load, potentially triggering thermal shutdown at 150C. At 40 MIPS with all peripherals active, estimated power consumption is approximately 60 mA from VDD - the EP keeps theta_JA low for sustained operation.
Keep the ICSP clock (PGC, pin 10) and data (PGD, pin 11) traces short and away from switching signals. Per Microchip ICSP design guidelines, add a 4.7 kohm pull-up resistor on MCLR (pin 1) to VDD, and route the ICSP connector near the pins to avoid programming failures. Avoid running PWM signals directly under the QFN package, as this introduces noise into ADC readings via capacitive coupling.
Estimated: Do not apply voltage to any pin before VDD reaches 1.5V - this can cause latch-up via the ESD protection diodes. When using the internal FRC oscillator at 7.37 MHz, enable the PLL with FPLLIDIV=1, FPLLMUL=21 to achieve 40 MIPS, but allow 1 ms lock time before peripheral operation. Common pitfall: leaving the JTAG pins (or alternatively, depending on variant: the alternate function pins) unconfigured - they default to analog input mode, which can cause excess current draw if floating.
