PIC32MX430F064LT-I/PT Visão geral
A 32-bit microcontroller (MCU) is a single-chip computer built around a 32-bit data path, allowing it to handle larger arithmetic operations, wider registers, and higher code density than its 8- or 16-bit predecessors. The PIC32 family, based on the MIPS M4K core, sits in Microchip's mid-range performance tier and occupies the niche between 8-bit PIC MCUs and higher-end Cortex-M devices. Within the broader taxonomy, a 32-bit MCU belongs to embedded microcontrollers -> microcontrollers -> integrated circuits -> semiconductors.
Key features include 100 MHz core speed with 150 DMIPS performance, USB-OTG full-speed for device/host/OTG roles, a 10-bit 1 Msps ADC with up to 16 channels, and CTMU for capacitive touch and time measurement. The part supports 5-bit programmable slew rate on I/O and runs from 2.3 V to 3.6 V across the -40 °C to +85 °C industrial temperature range. On-chip DMA enables peripherals to move data independently of the core.
The PIC32MX430 family uses a 5-stage pipelined MIPS32 M4K core, separate 16 KB instruction and 4 KB data caches, and a 12 KB auxiliary Flash block dedicated to bootloader storage. Its peripheral set mirrors the larger PIC32MX5/6/7 families but with reduced I/O count and memory, allowing drop-in scaling within the same development tools (MPLAB X, Harmony). The device supports serial communication through up to six UART, two SPI/I2S, and two I2C ports.
Typical applications include USB peripherals (HID, CDC, mass storage), capacitive touch human-machine interfaces, low-cost graphical LCD control, motor control BLDC/PMSM drivers, and industrial sensor hubs. The combination of USB-OTG, DMA, and CTMU is particularly attractive for touch-enabled consumer devices that also need to communicate with a host PC.
When designing with this part, allocate the auxiliary Flash region if a USB bootloader is planned, and use the CTMU's precision current source for accurate touch measurements. Decoupling must include a 0.1 µF ceramic capacitor per VDD/VDDIO pair, plus a bulk 10 µF tantalum or ceramic near the supply pins.

Aplicações típicas
PIC32MX430F064LT-I/PT é adequado para 6 aplicaçãos: USB Human Interface Device (HID), Capacitive Touch HMI, Low-Cost Graphical LCD Control, BLDC / PMSM Motor Control, Industrial Sensor Hub / Data Logger, Audio Playback / USB Audio DAC.
USB Human Interface Device (HID)
The PIC32MX430F064LT-I/PT is well-suited to USB HID peripherals such as keyboards, mice, and custom input devices, thanks to its integrated USB 2.0 Full-Speed OTG controller and 100 MHz MIPS M4K core. The CTMU enables capacitive touch sensing on keypads or sliders without an external touch controller. 64 KB Flash comfortably fits USB HID class drivers plus application firmware, and 16 KB SRAM handles HID report buffers without DMA pressure. The 100-pin TQFP package exposes all 85 GPIO plus USB D+/D- for direct connector wiring, eliminating the need for an external transceiver. Compared to a discrete USB controller plus 8-bit MCU, this single-chip integration reduces BOM and PCB area.
Recomendado
Capacitive Touch HMI
The integrated CTMU (Charge Time Measurement Unit) makes the PIC32MX430F064LT-I/PT a strong choice for capacitive touch human-machine interfaces, including appliance control panels, industrial keypads, and consumer electronics with slider/wheel input. The CTMU delivers calibrated current sources with sub-nA resolution, allowing accurate touch detection even through 3 mm plastic overlays. Combined with DMA-driven ADC sampling and the 10-bit 1 Msps ADC, the part can scan 16 touch electrodes in under 200 µs while leaving the CPU free for higher-level HMI logic. The 64 KB Flash budget supports MPLAB Harmony touch library plus custom GUI firmware in a single-chip solution.
Recomendado
Low-Cost Graphical LCD Control
For small graphical user interfaces (128x64 monochrome or 320x240 TFT panels), the PIC32MX430F064LT-I/PT offers enough performance to drive displays via its Parallel Master Port (PMP) peripheral at up to 25 MHz pixel throughput. The 100 MHz core and 5-stage pipeline enable efficient frame-buffer management without DMA starvation, while the 16 KB SRAM buffers a partial scanline to free the CPU for application work. The part's 85 GPIO cover data lines, control signals, and backlight PWM without external glue logic. Compared to higher-end PIC32MX5/6/7 families, this part is the most cost-effective entry point for cost-sensitive graphical products.
Recomendado
BLDC / PMSM Motor Control
The PIC32MX430F064LT-I/PT provides the necessary compute and peripheral mix for sensorless or Hall-sensor BLDC and PMSM motor control up to several hundred watts. Its 5-output PWM module with complementary mode and dead-time insertion drives three-phase inverters directly, while the 10-bit 1 Msps ADC samples back-EMF or phase currents with sub-microsecond latency. The DMA-fed ADC offloads conversion cycles from the MIPS core, allowing field-oriented control (FOC) loops to run at the rated 100 MHz without stall. The part's industrial -40 °C to +85 °C operating range supports under-hood and outdoor industrial deployments.
Recomendado
Industrial Sensor Hub / Data Logger
The PIC32MX430F064LT-I/PT's combination of USB-OTG, UART, SPI, I2C, and 10-bit ADC makes it a flexible hub for aggregating multiple industrial sensors and forwarding data to a host PC or gateway. The 16 KB SRAM is sufficient for circular sensor data buffers, while 64 KB Flash hosts the USB CDC class driver plus application protocol stacks (Modbus RTU, custom binary). The CTMU can be repurposed for resistance-based temperature or strain measurements using its calibrated current source. The 100-pin TQFP exposes all required peripheral pins plus 85 GPIO for status LEDs and control outputs in a compact industrial enclosure.
Recomendado
Audio Playback / USB Audio DAC
For low-cost USB audio DACs and headphone amplifiers, the PIC32MX430F064LT-I/PT integrates the USB 2.0 Full-Speed peripheral, two I2S interfaces, and DMA to deliver a single-chip USB-to-I2S bridge. Its 100 MHz core handles USB isochronous transfers and I2S frame assembly with ample margin, while the 16 KB SRAM buffers at least one millisecond of audio data at 48 kHz stereo. The CTMU is unused in this application but costs nothing if already present in the chosen part. Compared to dedicated USB audio controllers, this MCU approach allows custom DSP effects and volume control in firmware.

Notas de projeto
Estimated: Power consumption at 100 MHz, 3.3 V with all peripherals active is approximately 70 mA (core) plus 10-20 mA (peripherals), totaling ~85 mA. The USB transceiver (VUSB pin) adds 15 mA during active USB traffic. Decouple each VDD pin with a 0.1 µF X7R ceramic capacitor placed within 5 mm of the pin, plus one bulk 10 µF ceramic at the supply entry point. For USB applications, place a 0.1 µF + 4.7 µF capacitor pair directly at the VUSB pin to meet USB-IF inrush current requirements.
Route the 100-pin TQFP with at least 4-layer PCB (signal/ground/power/signal) and stitch grounds via the inner ground plane to minimize EMI on the USB differential pair (D+/D-). Keep the 12 MHz primary oscillator traces short and symmetric to prevent duty-cycle distortion, and place the load capacitors within 3 mm of the OSC1/OSC2 pins. The USB D+/D- traces must be 90 ohm differential, length-matched within 150 mil, and routed over a continuous ground plane for USB-IF compliance.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kohm pull-up resistor and add a 100 nF decoupling capacitor for noise immunity. The VUSB pin must be powered (3.3 V) even in non-USB applications to keep the USB transceiver in a defined state; floating VUSB can cause erratic current draw. The ICSP programming pins (PGECx/PGEDx) must be accessible on the PCB for in-circuit programming and debugging via MPLAB ICD/PICkit tools.
