PIC32MX430F064HT-V/MR 概要
A 32-bit microcontroller is a system-on-chip that combines a 32-bit CPU core, Flash program memory, SRAM data memory, and a rich peripheral set (ADC, timers, communication controllers, DMA) into a single IC. The PIC32MX family belongs to the broader hierarchy of embedded MCU -> RISC microcontroller -> 32-bit MCU -> semiconductor. Compared to 8/16-bit MCUs, a 32-bit core like the M4K executes arithmetic and DSP operations in fewer cycles, enabling faster protocol handling and richer UI layers without an external coprocessor.
Key features of the PIC32MX430F064HT-V/MR include 64 KB Flash (64K x 8), 16 KB SRAM, USB-OTG full-speed on-chip transceiver, two I2S/SPI modules for digital audio, a 10-bit 1 Msps ADC with up to 28 analog inputs, a 16-channel DMA controller for CPU-offload data movement, an integrated CTMU for capacitive touch sensing, and parallel master port (PMP) for graphics or external memory. The "-V" suffix denotes AEC-Q100 Grade 2 automotive qualification, -40C to +105C operating range.
The M4K core uses a 5-stage pipeline and dual-issue DSP extensions, achieving 1.56 DMIPS/MHz and supporting MIPS16e code compression to maximize Flash density. Hardware multiply/divide and zero-overhead loop nesting accelerate DSP loops for audio codecs, motor control compensation, and crypto primitives. The fail-safe clock monitor with two watchdogs ensures deterministic recovery from oscillator faults - a critical feature in automotive and industrial deployments.
Typical applications include automotive body and infotainment HMIs with capacitive touch panels, USB audio bridges and USB-to-UART converter dongles, motor control for small BLDC and stepper actuators, IoT gateways bridging USB device peripherals to BLE/Wi-Fi modules, and industrial operator panels. The USB-OTG + DMA combination is particularly well-suited to data-logger front-ends.
Design considerations for this part include ensuring the exposed pad on the 64-VQFN is soldered to a sufficient copper pour for thermal relief, using the internal LDO or external 3.3V regulator as appropriate, and isolating analog AVss/AVdd from digital supplies. The CTMU pin assignments must be reserved and the touch firmware library configured per Microchip's MHC configuration to avoid false triggers on noisy panels.

主な用途
PIC32MX430F064HT-V/MR の用途: 6 件s: Automotive HMI with Capacitive Touch, USB Audio Bridge Dongle, Industrial USB Data Logger Front-End, Small Motor Control (BLDC / Stepper), IoT Edge Gateway with USB Device Bridge, Operator Panel / Industrial HMI Display.
Automotive HMI with Capacitive Touch
The PIC32MX430F064HT-V/MR's AEC-Q100 Grade 2 qualification, integrated CTMU capacitive-touch engine, and 64-pin VQFN form factor make it a strong fit for automotive human-machine-interface panels such as climate-control sliders, rear-seat entertainment keypads, and steering-wheel switch matrices. The CTMU pairs with the 10-bit 1 Msps ADC to resolve sub-pF capacitance changes with hardware noise filtering; Microchip's mTouch firmware library handles scan sequencing and baseline tracking. The 80 MHz M4K core debounces 32+ touch channels in real time while running a USB CDC link to the head unit for telemetry. The /MR exposed-pad package provides the thermal margin needed for sun-load ambient temperatures up to +105C inside instrument clusters and door modules.
おすすめ
USB Audio Bridge Dongle
The PIC32MX430F064HT-V/MR's USB 2.0 Full-Speed OTG controller with on-chip transceiver and dual I2S ports lets it serve as a compact USB-to-I2S audio bridge between a host PC and an external DAC/amplifier. The 16-channel DMA controller moves I2S samples between the USB endpoint buffer and the I2S TX register without CPU intervention, leaving the 80 MHz M4K core free for sample-rate conversion and volume processing. Hardware multiply/divide accelerates biquad filter stages needed for headroom tuning. The 64 KB Flash accommodates a USB Audio Class 1 driver stack with HID volume/control channel - sufficient for most consumer DAC dongle designs. The 64-VQFN MR package is small enough for inline dongle enclosures and reflows cleanly on standard FR-4.
おすすめ
Industrial USB Data Logger Front-End
The PIC32MX430F064HT-V/MR's USB-OTG device mode, dual UART, dual I2C, dual SPI, and 16-channel DMA form a compact data-logger front-end that bridges sensor peripherals (UART GPS, I2C IMU, SPI flash storage) to a host PC over USB CDC or USB MSD. The 16 KB SRAM buffers DMA streams from each peripheral while the M4K core performs real-time CRC stamping and FATFS file writes to an external SD card over SPI. The automotive -V grade lets the same firmware ship into factory-floor logging equipment that experiences elevated ambient temperatures. The 64-pin VQFN (MR) with exposed pad provides the IO count (28 ADC inputs, multiple comm peripherals) needed for multi-sensor aggregation without an external bus expander.
おすすめ
Small Motor Control (BLDC / Stepper)
The PIC32MX430F064HT-V/MR delivers deterministic PWM and ADC sampling required for sensorless BLDC or stepper motor commutation. The 80 MHz core runs Microchip's MPLAB Harmony Motor Control framework with field-oriented control (FOC) at switching frequencies up to 20 kHz, while the 10-bit 1 Msps ADC samples back-EMF on three phases within the PWM window. The dual I2S/SPI channels can drive a digital Hall-effect encoder or a Sigma-Delta current sense amplifier. The AEC-Q100 Grade 2 qualification means the same firmware can deploy in automotive auxiliary pumps, HVAC flaps, and seat adjusters - not just industrial conveyor drives. The 64-VQFN MR package exposes enough GPIO for three-phase gate drivers plus fault inputs and brake control.
おすすめ
IoT Edge Gateway with USB Device Bridge
The PIC32MX430F064HT-V/MR is well-suited as the USB-device side of an IoT edge node: it aggregates I2C sensor traffic, exposes the data as USB CDC or USB HID to a host SBC, and forwards control messages over UART to a downstream BLE/Wi-Fi module. The 16-channel DMA offloads I2C/SPI byte streams from the core, freeing the 80 MHz MIPS M4K to run a small embedded HTTP-to-UART gateway or a Modbus-to-USB bridge. The 64 KB Flash is sufficient for a USB CDC stack plus a slim Modbus RTU master library. The -V automotive grade extends the design's reach into telematics control units and vehicle-to-cloud gateways where commercial-grade MCUs are not acceptable.
おすすめ
Operator Panel / Industrial HMI Display
The PIC32MX430F064HT-V/MR's parallel master port (PMP) can directly drive a TFT LCD with a modest controllerless interface, while the 16 KB SRAM holds a UI framebuffer for icons and 8x8 fonts. The dual SPI/I2S ports attach to a touchscreen controller and an audio feedback buzzer/amplifier. The USB-OTG port allows field firmware updates via a USB stick. The -V automotive grade enables the same panel design to be deployed on agricultural vehicles, construction equipment, and forklifts that see extended sun-load and vibration. The 64-VQFN MR package with exposed pad keeps the board footprint under 25x25 mm - small enough for compact 3.5-inch panels.

設計ノート
The 64-VQFN exposed pad is the primary thermal path. Solder it to a continuous ground copper pour of at least 100 mm^2, stitched with a 4x4 array of 0.3 mm thermal vias. Without sufficient copper, junction temperature can exceed +105C in enclosed automotive environments even at modest 80 MHz operation. Estimated: at 80 MHz, VDDCORE current is approximately 30 mA, so total dissipation is roughly 100 mW at 3.3V - thermal margin is acceptable with a proper pour but tight in sealed enclosures.
Place a 10uF bulk + 0.1uF high-frequency bypass capacitor pair within 2 mm of every VDD/VSS pin pair on the 64-VQFN. Keep analog AVdd/AVss traces short and isolated from digital switching lines - the ADC's 10-bit 1 Msps performance degrades noticeably with digital noise coupling. The USB D+/D- lines require a 27-ohm series resistor (not 22-ohm, not 33-ohm) close to the IC pins, plus a 90-ohm differential characteristic impedance on the USB trace pair per USB 2.0 FS layout rules.
Program/debug pins PGEC1/PGED1 (RB1/RB0) must be accessible after PCB assembly - either brought out to test pads or a header - because the -V AEC-Q100 variants are typically programmed in-circuit on the assembled board rather than pre-programmed at the factory. Reserve at least one UART pair as a fallback debug console output even if USB CDC is the primary interface.
Do not enable the CTMU touch engine without first configuring the relevant ADC channels and assigning CTMU charge-current trim - misconfigured CTMU reads can give false touch events or saturate the ADC. The 64 KB Flash with USB stack requires careful memory budgeting; consider using the PIC32MX450F256 variant if your USB CDC + HID + vendor stack does not fit in 64 KB. The automotive -V parts are NOT drop-in for firmware expecting -I temperature behavior - bootloader USB descriptors and clock trim values differ between grades.
