PIC32MX430F064HT-V/PT Overview
A 32-bit MCU (microcontroller) is a single-chip computer that combines a 32-bit CPU core, program Flash, data SRAM, and a rich set of peripherals (timers, ADC, communication controllers, I/O) on one silicon die. PIC32MX3/4 devices sit in Microchip's PIC32 hierarchy between the lower-pin-count PIC32MX1/2/3 entry family and the higher-performance PIC32MX5/6/7 and PIC32MZ lines, giving designers a balance of cost, peripherals, and code density. The M4K core delivers 1.56 DMIPS/MHz, executes most instructions in a single cycle, and is supported by MPLAB XC32 and the MPLAB Harmony framework.
Key differentiating features of the PIC32MX430F064HT-V/PT include 64KB single-cycle Flash, 16KB SRAM, hardware DMA, USB-OTG full-speed device/host, two I2S channels, CTMU for capacitive touch, a 10-bit 1MSPS ADC with up to 28 channels, four UART, two I2C and two SPI/I2S ports. The '430' family adds USB-OTG and DMA over the '420', while the 'HT' temperature grade is the -40C to +105C industrial range and the 'V' speed suffix indicates 80MHz. Programming is via 2-wire ICSP or JTAG.
Typical applications include USB peripherals (Human Interface Devices, CDC serial, mass storage), industrial control front-ends with capacitive touch, audio accessories that route I2S to a Class-D amplifier, low-cost graphics terminals with Parallel Master Port, and motor-control development boards. The 64-pin TQFP gives enough I/O for color TFTs and motor feedback signals while still being hand-solderable on prototype boards.
Designers should budget decoupling: place a 100nF X7R next to every VDDCORE/VDD pin pair plus a bulk 4.7uF or 10uF near the regulator. The USB bus requires a 90 ohm differential pair, ESD protection (such as USBLC6-2), and a 10uF VBUS reservoir if host mode is used. For capacitive touch, dedicate one CTMU channel per electrode and follow the mTouch reference layout.

Typical Applications
PIC32MX430F064HT-V/PT is suitable for 7 applications: USB HID / CDC Peripheral, Capacitive Touch Control Panel, Audio Accessory with I2S DAC, Industrial HMI Front-End, Sensor Hub with DMA Streaming, Low-Cost Graphics Terminal, Motor Control Development Platform.
USB HID / CDC Peripheral
The PIC32MX430F064HT-V/PT fits USB Human Interface Device and CDC serial designs because of its integrated USB-OTG full-speed transceiver, 16KB SRAM for descriptor and endpoint buffers, and DMA that offloads bulk transfers from the core. At 80MHz the M4K core leaves headroom for HID report parsing, boot-loader tasking and command protocols without starving USB isochronous endpoints. Place the device between the USB Type-B connector and a 3.3V LDO, add a USBLC6-2 ESD array on D+/D- and a 90 ohm differential pair, and use Microchip's MLA USB stack with the Harmony framework. The 64-pin TQFP gives enough GPIO for status LEDs, button inputs and a debug UART alongside the USB pins.
Recommended
Capacitive Touch Control Panel
The PIC32MX430F064HT-V/PT suits mTouch capacitive touch panels because of its CTMU peripheral that measures capacitance to sub-pF resolution, its 16KB SRAM for gesture/filters state, and up to 28 ADC channels that double as extra analog inputs. At 80MHz, firmware-driven scans of 16-24 electrodes fit well under the 10ms response window for sliders and wheels. Route each electrode to a dedicated CTMU channel and follow Microchip's mTouch PCB guidelines for sensor pattern, ground fill and ground-shield traces. Use the PIC32MX330F064HT-I/PT as a cost-down alternative when USB and DMA are not needed; both share the TQFP-64 footprint.
Recommended
Audio Accessory with I2S DAC
The PIC32MX430F064HT-V/PT is well matched to I2S-output audio accessories such as Bluetooth receivers, USB speakers, and digital mixers because it provides two I2S channels, DMA that streams audio without CPU load, and 16KB SRAM for sample buffers. At 80MHz, the MCU can simultaneously run USB audio class, perform sample-rate conversion and drive a Class-D amplifier's PWM feedback. Place the device near the I2S DAC, route MCLK/BCLK/LRCK as matched-length traces under 50mm, and decouple each VDD pin with a 100nF X7R plus a bulk 10uF. The 64-pin TQFP leaves enough GPIO for rotary encoder, status LEDs and an auxiliary SPI display.
Recommended
Industrial HMI Front-End
The PIC32MX430F064HT-V/PT fits industrial HMI panels and operator interfaces because of its -40C to +105C HT temperature grade, 64KB Flash for graphical menus, USB-OTG for configuration ports, and 64-pin TQFP that exposes enough GPIO for keypad scan, encoder input and LCD data bus. At 80MHz the M4K core can refresh a small TFT while simultaneously polling UART sensors and updating a Modbus stack. Place a 1kV isolated DC-DC near the supply pin and add TVS diodes on field-side connectors; the device's 5V-tolerant GPIO simplifies interface to legacy 5V logic. The PIC32MX370F512HT-V/PT scales up to 512KB Flash if larger display fonts and fonts tables are required.
Recommended
Sensor Hub with DMA Streaming
The PIC32MX430F064HT-V/PT fits multi-sensor data-acquisition hubs where DMA streams ADC samples into SRAM while the CPU runs the user algorithm. With hardware DMA, up to 28 ADC channels at 1MSPS, two SPI and two I2C controllers, and 16KB RAM for circular buffers, the part covers IMU + pressure + temperature sensor fusion in one chip. At 80MHz the M4K core executes FFTs and basic Kalman filtering in real time without dropping samples. Keep analog VDD and digital VDD separated by ferrite beads at the regulator, and add 100nF plus 10uF decoupling on each VDD pin; reserve pin 1 (MCLR) with a 10k pull-up to VDD.
Recommended
Low-Cost Graphics Terminal
The PIC32MX430F064HT-V/PT can drive small TFT or OLED terminals through its Parallel Master Port (PMP) peripheral, GPIO, or SPI, with 64KB Flash holding fonts, bitmaps and protocol parsers. The M4K core at 80MHz sustains 20-30 FPS on 320x240 panels via PMP in 8-bit mode with DMA-accelerated framebuffer refresh. Place the device close to the display connector, length-match the PMP data bus to within 5mm, and add series resistors on each line to dampen reflections. Combine with a SPI-driven SD card for asset graphics and a UART for host commands. For larger screens consider the PIC32MX350F256H-V/PT which adds more RAM for double-buffering.
Recommended
Motor Control Development Platform
The PIC32MX430F064HT-V/PT is a viable controller for low-power BLDC, stepper and FOC motor platforms because it exposes two PWM/OC channels per timer, QEI support on one timer, 1MSPS ADC for back-EMF sensing, and a 64-pin TQFP with enough pins for 3-phase gate drivers and current-sense amplifiers. At 80MHz the M4K core can run sensorless FOC on small outrunners or PMSMs when paired with a fast enough ADC. Keep the analog current-sense path short and away from the gate-driver switching node, route the QEI inputs as a matched-length differential pair, and bulk-decouple the motor-supply pin if the board integrates a small driver stage.

- Higher Flash and SRAM density at the same pin count (vs PIC32MX420F032HT-40I/PT)
Design Notes
Estimated: at 80MHz the core draws approximately 35-45 mA from VDDCORE at 1.8V. Decouple each VDD/VDDCORE pin pair with a 100nF X7R ceramic placed within 3mm of the pin, and add a single 4.7uF to 10uF bulk capacitor near the regulator. Use a low-noise LDO such as MCP1700-3302E or a small buck regulator if the supply is above 3.6V. According to the family datasheet, the internal 1.8V regulator is only active when VDD is in the 2.5V-3.6V range; below 2.5V VDDCORE must be supplied externally.
Keep the USB differential pair (D+ / D-) at 90 ohm differential impedance with traces under 50mm and length-matched within 2mm. Place the USBLC6-2 ESD array as close as possible to the connector, and route VBUS through a 10uF decoupling capacitor if host-mode operation is required. Per the family datasheet, VBUS sensing requires the VBUS pin to be connected even in device-only mode when the internal pull-up is enabled. Reserve pin 1 (MCLR) with a 10k pull-up to VDD and a 100nF cap to ground for in-circuit serial programming.
A common mistake is leaving the JTAG pins (PGECx/PGEDx) floating - they must be pulled to known states via internal pull-ups or external resistors, otherwise debug-session connect failures and random NMC (non-maskable interrupt) resets may occur. According to Microchip application note AN1094, the PIC32MX also requires the external POSC oscillator pins to be tied to ground if not used, otherwise the part may enter an undefined clock domain at power-up. The 80MHz V-grade parts require a 4MHz-25MHz primary oscillator input multiplied by the PLL; verify the PLL loop filter components match the family datasheet's reference schematic.
Estimated: the TQFP-64 package has theta_JA around 40-45 C/W on a standard 4-layer JEDEC test board with copper pour. At 80MHz and full peripheral activity the device typically dissipates around 200-300 mW, so the junction rises 8-15C above ambient - well within the 105C industrial limit. For enclosed housings above 60C ambient, increase copper area on the inner ground planes or upgrade to the 64-pin QFN variant (RG package) with thermal pad for lower thermal resistance.
