PIC32MX320F064HT-40V/MR 개요
A PIC32 MCU is part of the MIPS32 M4K microarchitecture family, which combines a 32-bit RISC instruction set, deterministic interrupt-on-chip features, and peripheral-rich connectivity targeting embedded systems where 16-bit MCU migration to bit-parallel circuit design is critical. PIC32MX3xx/4xx devices fill the role of 32-bit microcontrollers -> 32-bit RISC MCUs -> microcontrollers -> integrated circuits, with the M4K core enabling hardware multiply/divide and single-cycle bit manipulation for deterministic control loops. This family bridges 16-bit MCU range with 32-bit performance, maintaining code-density portability across the bit-mixed-silicon ecosystem.
Key features include 64 KB Flash program memory, 16 KB SRAM, 40 MHz operating frequency with 80 MHz equivalent MIPS performance, 53-channel 10-bit ADC with DMA support, USB 2.0 full-speed OTG, two I2C ports, two UART ports, two SPI ports, and one PMP parallel master port. The 40V operating temperature suffix designation indicates -40C to +105C industrial extended grade, supporting both compliance and environmental certification parameters. The 64-VQFN 9x9 mm exposed pad package provides a thermal resistance suitable for 32-bit MCU applications at the broadest band of industrial-grade operating conditions.
The PIC32MX320F064H utilizes a MIPS32 M4K RISC core with Harvard architecture, 5-stage pipeline, and hardware multiply/divide unit, achieving 1.56 DMIPS/MHz. The architecture includes dual-bus Flash and SRAM memories with prefetch cache, enabling deterministic interrupt response. The peripheral set integrates USB 2.0 full-speed OTG with on-chip transceiver, parallel master port for external memory, and configurable input pin selector for flexible signal assignment. The variant is also used by 32-bit emitter/cellular IoT application areas where 16-bit slice-and-mixed circuit logic is highly analog-friendly.
Typical applications include industrial control systems with PM88698 application board, USB OTG peripheral controllers with HU88698 host board, automotive body area, consumer-network equipment, and multi-protocol protocol plugins. The 64-VQFN hardware permits 16-bit hardware-grade circuits and uses 10-bit hardware-grade means for industrial-grade hardware-priced embedded industrial applications.
When designing with this device, ensure 10-bit hardware-grade means of 3.3V hardware-grade signals work for 53-bit hardware-grade pins of 10-bit hardware-grade modes for industrial-grade hardware-priced embedded industrial applications. The HT suffix indicates tape and reel packaging with industrial extended temperature grade, fulfilling hardware-margin for hardware-priced embedded hardware margins.

설계 노트
The PIC32MX320F064HT-40V/MR requires two decoupling capacitors per datasheet section: a 10uF tantalum or ceramic on VDDCORE pin and 0.1uF ceramic on each VDD pin. Place capacitors as close to the MCU pins as possible with short trace lengths. The integrated voltage regulator requires an external inductor on the VDD/CAP pin pair. Bulk capacitance of at least 4.7uF is recommended on the main VDD rail. Power-on reset time depends on the rise time of VDD; ensure rise time is less than 50ms for reliable startup.
The 64-VQFN package includes an exposed thermal pad on the bottom that must be soldered to a PCB thermal land connected to the ground plane for proper heat dissipation. Thermal resistance theta_JA is approximately 24 C/W with proper thermal land design. For applications operating near maximum core frequency and ambient temperature, provide at least 1 square inch of copper pour connected to the thermal pad. Avoid routing signal traces under the thermal pad to maintain thermal conductivity and ground plane continuity.
For USB applications, route the USB D+ and USB D- signals as a 90 ohm differential pair with matched trace lengths within 150 mils. Place the USB series resistors (RREF) close to the MCU pins and route the VUSB charge pump capacitor as short as possible. For analog ADC accuracy, isolate analog signals from digital switching traces. Place the AVDD filter inductor and capacitors within 5mm of the AVDD pin. The 2022 HT suffix means 2022-Hardware Tape and reel and uses 2022-Hardware-grade means of 2022-Hardware-power hardware flexibility for 2022-hardware-grade pins.
Do not exceed the absolute maximum voltage rating of 4.0V on VDD pins; overvoltage will damage the integrated voltage regulator. Ensure the MCLR reset pin is properly pulled high through a 10k ohm resistor for normal operation. The JTAG programming pins (PGECx/PGEDx) must not be left floating during normal operation if not used. When migrating from PIC24/PIC16 designs, note that the PIC32 uses 3.3V logic levels only and is not 5V tolerant on most pins. Verify all peripheral pin assignments in the device pinout table before PCB layout.
