PIC32MX664F064HT-V/MR 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, timers, communication peripherals, and analog/digital I/O on one die. The PIC32MX6xx family belongs to the broader category of 32-bit microcontrollers -> embedded microcontrollers -> microcontrollers -> integrated circuits. The PIC32 architecture extends Microchip's legacy 16-bit PIC instruction set to a MIPS-based 32-bit core, delivering substantially higher computational throughput (80 MHz / 1.56 DMIPS/MHz per core) while retaining the well-known MPLAB X IDE and Harmony framework development environment.
Key features of the PIC32MX664F064HT-V/MR include USB On-The-Go (OTG) with integrated transceiver, a 10-bit ADC with up to 16 channels and 1 Msps conversion rate, DMA controller for offloading CPU data movement, and 53 general-purpose I/O pins. The 64 KB Flash is supported by 32 KB SRAM, plus a 4 KB USB RAM area for full-speed USB endpoints. Connectivity includes up to two I2C, two SPI, and five UART modules, making the device well suited to multi-peripheral embedded systems.
Architecture-wise, the device uses a Harvard-style bus with separate Flash and RAM paths, a 5-stage MIPS32 M4K pipeline, and a peripheral bus running at half system clock. The integrated USB 2.0 full-speed OTG controller (12 Mbps) includes a dedicated DMA channel and a 4 KB endpoint buffer, eliminating external PHY requirements for many HID, CDC, and MSC designs. The 10-bit ADC can pair with DMA to sample multiple analog sensors without CPU intervention.
Typical applications include USB peripherals and HID devices, industrial sensor interfaces with USB diagnostics, consumer electronics with embedded control, and low-power connected nodes powered from USB or 3.3 V rails. The VQFN-9x9 package with exposed pad provides good thermal performance for the 0.5 W device dissipation.
When designing with this part, verify the operating voltage (2.3-3.6 V) matches your rail, plan the trace layout to keep the USB DP/DN pair length-matched, and connect the exposed pad to a continuous ground plane for both thermal and EMI performance. The device carries a '-V' suffix denoting the automotive-grade temperature range of -40 C to +105 C.

設計ノート
The VQFN-64 package has an exposed thermal pad (EP) on the underside that must be soldered to a continuous PCB ground plane. Per Microchip's PIC32MX family hardware design guidelines, place an array of thermal vias (typically 0.3 mm drill on 0.5 mm pitch) directly under the EP to provide a low-impedance thermal path to inner/outer ground planes. Failure to solder the EP correctly can lead to junction temperature rise and erratic USB behavior at full bus loads.
Route the USB D+ (pin 39) and D- (pin 40) signals as a 90-ohm differential pair with length matching within 150 mil. Per the Microchip PIC32MX6xx USB hardware design checklist, keep the D+/D- traces short, avoid right-angle bends, and place the VUSB decoupling capacitor (typically 0.1 uF + 4.7 uF) as close to pin 41 as possible. Add a common-mode choke if the design must pass EN 55022 Class B radiated emissions on the USB cable.
The PIC32MX664F064HT-V/MR has multiple VDD/VSS pin pairs (pins 8, 28, 33, 62 for VDD and pins 20, 27, 34, 42, 61 for VSS). Each VDD pin must have its own 0.1 uF decoupling capacitor placed within 3 mm of the pin per Microchip's PIC32MX family hardware design guidelines. A bulk 10 uF tantalum or ceramic capacitor on the main 3.3 V rail is also recommended. Do not rely on a single VDD bypass to serve multiple supply pins.
When migrating code from a 16-bit PIC24 or dsPIC part to the PIC32MX664, the peripheral register layout and interrupt vector structure differ significantly. Use the Microchip MPLAB Harmony framework or MCC (MPLAB Code Configurator) to avoid register-level mistakes. Also, note that the PIC32MX6xx family has silicon revision errata affecting USB DMA behavior under specific conditions - consult DS80339 errata before finalizing the design.
