PIC32MX430F064HT-I/PT Overview
A PIC32MX3/4 series microcontroller is a 32-bit RISC MCU built on the MIPS32 M4K core and a 5-stage pipeline, bridging the gap between legacy PIC16/PIC24 designs and the higher-end PIC32MZ family. It belongs to the broader PIC32 family (32-bit microcontroller -> RISC MCU -> embedded processor -> semiconductor), runs from a 2.3-3.6V supply, and exposes industry-standard peripherals (USB-OTG, UART, SPI, I2C, I2S) so engineers can port code across the family. The "H" suffix in the die name indicates a 64-pin variant; the "T" suffix indicates tape-and-reel packaging.
Key features include 64KB single-cycle Flash, 16KB SRAM, five 16-bit timers/counters, two I2S/SPIs, two I2C, USB-OTG device/host, a 16-channel 10-bit ADC, an integrated CTMU for capacitive touch, four-wire EJTAG, and a Peripheral Pin Select (PPS) engine that lets the user remap most digital peripherals to any I/O. The 100MHz core delivers up to 130 DMIPS while drawing approximately 30 mA/MIPS active and 30 uA/MIPS in sleep, making the device well suited to battery-powered and USB-powered designs.
Architecturally, the PIC32MX430 uses Harvard-style separate instruction and data buses with prefetch cache, a single-cycle hardware multiply/divide unit, and a dedicated DMA controller with eight channels that offload peripheral transfers from the core. The integrated USB-OTG PHY plus the on-chip CTMU simplify BOM by removing the need for an external touch controller or external PHY.
Typical applications include USB audio (USB-I2S bridge DACs/headsets), capacitive-touch user interfaces for appliances and IoT devices, low-cost graphics-enabled HMI displays, motor-control BLDC/PMSM sensor boards, and industrial sensor hubs. Designers also choose it for educational platforms and hobbyist MCU development kits thanks to MPLAB Harmony and the PICkit 4 toolchain.
When designing with the PIC32MX430F064HT-I/PT, ensure the VDD/VSS pins have adequate decoupling (100 nF ceramic per pin) and that the USB VBUS line includes the standard 10 uF + 100 nF bulk decoupling mandated by the USB 2.0 spec. The PPS feature avoids the need for any firmware pin re-mapping at board level.

Typical Applications
PIC32MX430F064HT-I/PT is suitable for 6 applications: USB Audio Class DAC / Headset, Capacitive Touch User Interface, Low-Cost Graphics HMI Display, BLDC / PMSM Motor Control Sensor Board, Industrial Sensor Hub with USB Logging, Educational MCU Development Platform.
USB Audio Class DAC / Headset
The PIC32MX430F064HT-I/PT is well suited to USB audio class 1.0 DACs and USB-I2S headsets because it integrates a USB-OTG full-speed PHY, two I2S channels, and 64KB Flash that comfortably holds the Microchip USB audio stack and a custom HID control interface. The 100MHz core decodes 48 kHz stereo 16-bit audio via the I2S port without DMA intervention, leaving 30-40% CPU headroom for volume control and EQ. The CTMU plus on-chip 10-bit ADC let the designer add capacitive-touch buttons for play/pause/skip without any external IC. Operate the MCU at 3.3V with 100 nF decoupling per VDD/VSS pair and the standard USB VBUS 10 uF + 100 nF bulk capacitor network.
Recommended
Capacitive Touch User Interface
The PIC32MX430F064HT-I/PT is an excellent host for capacitive-touch sliders, wheels, and matrix keypads because it integrates the CTMU (Charge Time Measurement Unit) that drives and measures up to 32 touch electrodes using only PCB pads plus the on-chip ADC. At 100MHz the core scans a 16-button matrix in under 2 ms with 12-bit equivalent resolution via oversampling. The 64KB Flash fits Microchip's mTouch library plus a USB or I2C host interface to a main processor. Designers can implement a 4x4 matrix with a single layer of copper plus 100 nF decoupling, eliminating dedicated touch ICs and reducing BOM cost by 40-60% versus discrete solutions.
Recommended
Low-Cost Graphics HMI Display
The PIC32MX430F064HT-I/PT drives 320x240 QVGA TFT displays via the Parallel Master Port (PMP) at 30 fps with only 30-50% CPU utilization, making it ideal for appliance front panels, industrial keypads, and HVAC thermostat UIs. Its 64KB Flash hosts Microchip's MLA graphics library plus a custom 4-bit font table; 16KB SRAM holds a single 320x240x2bpp framebuffer without external memory. The integrated USB-OTG enables firmware updates from a PC host, eliminating the need for a bootloader header. Pair with an ILI9341 SPI TFT or a 16-bit PMP interface for full-screen refreshes without flicker.
Recommended
BLDC / PMSM Motor Control Sensor Board
The PIC32MX430F064HT-I/PT functions as a sensor-input companion to a dedicated motor-driver IC in BLDC and PMSM systems, sampling Hall sensors and back-EMF via its 16-channel 1 Msps ADC and forwarding rotor-position data over SPI to the gate driver. The 5 timer/counter pairs support quadrature encoder input, PWM capture, and motor-speed measurement up to 100 kHz. USB-OTG enables live tuning and parameter logging from a PC GUI during motor characterization. The 100MHz MIPS32 M4K core runs sensorless observers (Back-EMF or BEMF ZCP) in software with sub-15 us loop time. Operate at 3.3V with isolated gate-driver supplies per industrial safety requirements.
Recommended
Industrial Sensor Hub with USB Logging
The PIC32MX430F064HT-I/PT aggregates data from I2C, SPI, and UART sensor clusters via its 8-channel DMA engine and exposes the stream to a PC through USB-OTG, replacing discrete USB-serial bridges with a programmable, field-upgradable hub. The dual I2S ports allow digital-microphone arrays for acoustic monitoring; the CTMU supports liquid-level sensing in industrial tanks. The 64KB Flash and 16KB SRAM buffer a 100 kHz sensor stream for up to 600 ms without dropouts. Pair the MCU with the MCP2221A for USB-CDC fallback when debugging serial sensors. Industrial-grade -40C to +85C operation tolerates factory-floor deployment without thermal management.
Recommended
Educational MCU Development Platform
The PIC32MX430F064HT-I/PT is widely adopted in university microcontroller courses and hobbyist dev kits because it offers 32-bit MIPS architecture at near-PIC24 pricing, with full MPLAB X IDE, MPLAB Harmony v3, and PICkit 4 toolchain support. The 64KB Flash fits Microchip's published lab exercises (USB, I2S, ADC, CTMU) plus student code; the 49 I/O pins provide enough GPIO for breadboard-based capstone projects. Industrial temperature rating allows use in teaching labs without climate control. Microchip's Curiosity Development Board (DM320104) integrates this part with an on-board debugger, accelerating classroom onboarding. The PPS engine lets students experiment with peripheral remapping without board rework.

Key Differentiators

- Tape-and-reel packaging for high-volume SMT (vs PIC32MX430F064H-I/PT)
Design Notes
Estimated: At 100MHz active, the PIC32MX430F064HT-I/PT draws approximately 30 mA/MIPS * 1.30 DMIPS/MHz = ~39 mA per MHz scaling, or ~30 mA active plus 30 uA/MHz in sleep. Place a 100 nF ceramic decoupling capacitor on every VDD/VSS pin pair (pins 10, 23, 61, 62 plus AVDD/AVSS pins 58/59) within 2 mm of the IC. Add a 4.7 uF bulk capacitor near pin 10 and a 10 uF + 100 nF USB VBUS decoupling network on pin 6 per the USB 2.0 specification. For battery-powered designs, use the device's deep-sleep mode to drop current below 1 uA when USB is suspended.
The TQFP-64 (PT) 10x10 mm package has 0.5 mm pitch leads requiring 0.25 mm trace width and 0.20 mm via drill for the escape routing. Use a 4-layer PCB with a continuous ground plane on layer 2 to provide a low-impedance return path for the 100MHz core. Route the 48MHz crystal traces (OSC1/OSC2) as short as possible (under 5 mm) and guard them with a ground pour to minimize EMI pickup. The USB D+/D- pair (pins 8/9) requires 90-ohm differential routing and a common-mode choke for USB-IF compliance testing.
The PIC32MX430F064HT-I/PT requires Microchip's XC32 compiler v2.50 or later and MPLAB Harmony v3 for USB stack and CTMU libraries; legacy MPLAB C32 code will not compile without migration. Do NOT forget the 10 kohm pull-up on MCLR (pin 60) or the device will reset intermittently. The PPS feature must be unlocked by clearing CFGCON.IOLOCK before any peripheral remap, otherwise I/O functions appear dead until the unlock sequence is executed in firmware. The CTMU calibration constants are unique per device and must be read from non-volatile memory at startup for accurate touch measurements.
Compliance Information
RoHS and REACH compliant per Microchip's environmental compliance documentation. Industrial temperature (-40C to +85C, I suffix) is NOT AEC-Q100 qualified; for automotive PPAP review the PIC32MX automotive-grade ordering codes separately. Lead-free matte-tin plating on TQFP-64 lands.
