PIC32MX430F064LT-V/TL - 80MHz 32-bit MCU, 64KB Flash, USB-OTG | Microchip
MPN: PIC32MX430F064LT-V/TL ✓ Hoạt độngPIC32MX430F064LT-V/TL Tóm tắt
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and configurable peripherals on one die. Within the broader taxonomy, MCUs sit under microprocessors, which sit under semiconductors and integrated circuits. The PIC32MX3/4 family specifically targets cost-sensitive 32-bit designs that previously used 16-bit controllers, giving designers an easy migration path with the MPLAB Harmony ecosystem.
Key features include 64KB (64K x 8) Flash, 16KB SRAM, up to 80MHz core clock, 5 channels of 10-bit ADC at up to 1 Msps, USB-OTG full-speed, two I2C, two SPI/I2S, two UART, DMA, CTMU for touch/proximity sensing, and an 8-bit PMP for graphics or external memory. The wide 2.5V/3.3V operating range lets it run from a single 3.3V regulator, and the 124-pin VTLA package exposes most peripherals on dedicated pins.
The PIC32MX430F064L uses a 5-stage pipelined MIPS32 M4K core with single-cycle hardware multiply/divide and tightly-coupled memory paths for deterministic interrupt latency. The integrated DMA offloads data movement between peripherals and RAM, freeing the core for application logic. The USB-OTG controller includes on-chip transceivers, requiring only an external ESD-protected connector to implement a full-speed device or host port.
Typical applications include low-cost USB peripherals, capacitive-touch human-machine interfaces, audio playback with two I2S channels, industrial sensor hubs with PMP, and small graphical HMI panels. The CTMU + ADC combination supports touch buttons, sliders, and proximity sensing without dedicated touch ICs. Designers migrating from PIC24 or PIC32MX1/2 families benefit from drop-in 32-bit performance upgrades.
When designing with this device, allocate careful attention to the 124-pin VTLA land pattern and use Microchip's VTLA land pattern specification to avoid thermal and soldering defects. Decouple VDD/VSS pairs with 100 nF ceramic caps placed within 3 mm of each pin pair, and keep trace lengths below 25 mm for USB DP/DM to pass USB compliance.
This page combines verified distributor pricing, same-brand drop-in alternatives in matching 124-pin VTLA packages, and practical design notes that go beyond the manufacturer datasheet to help BOM managers and embedded engineers source faster.

Ứng dụng tiêu biểu
PIC32MX430F064LT-V/TL phù hợp cho 6 Áp dụngs: USB Human Interface Device (HID) Peripheral, Capacitive Touch HMI Panel, Low-Cost Audio Player with I2S, Industrial Sensor Hub with PMP, USB-OTG Device Charger / Power Bank, Small Graphical HMI with Color TFT.
USB Human Interface Device (HID) Peripheral
The PIC32MX430F064LT-V/TL is well suited to USB-HID peripherals such as keyboards, mice, game controllers, and custom input devices. The integrated USB-OTG full-speed controller with on-chip transceiver eliminates the need for an external PHY, while the 80 MHz MIPS32 M4K core easily handles HID report polling at 1 kHz with cycles left over for LED animations or wireless protocol bridging. The 64 KB Flash accommodates HID descriptor stacks, debounce logic, and macro/firmware updates, while the 16 KB SRAM supports HID ring buffers and CDC notifications. Designers can implement bootloaders using Microchip's USB HID bootloader, allowing field firmware updates via the USB cable. Recommended companions include the MCP2200 USB-to-UART bridge for legacy peripherals and the PICkit 4 programmer/debugger for development.

Capacitive Touch HMI Panel
The CTMU peripheral combined with the 10-bit 1 Msps ADC makes the PIC32MX430F064LT-V/TL ideal for capacitive touch human-machine interfaces. mTouch firmware libraries from Microchip support up to 32 touch channels with water tolerance and proximity detection. Designers can implement sliders, wheels, buttons, and proximity wake-up without a dedicated touch IC. The 124-pin VTLA package exposes enough GPIO to support matrix-scanned key panels and I2C-driven segmented LCDs simultaneously. Trade-off: mTouch scan time scales with channel count, so beyond 24 channels designers should consider the PIC32MX450 family with a faster ADC. Typical companion chips include the MCP2210 USB-to-SPI bridge and AT24C256 EEPROM for HMI parameter storage.
Được đề xuất
Low-Cost Audio Player with I2S
The PIC32MX430F064LT-V/TL's dual SPI/I2S blocks and DMA controller enable low-cost audio playback from SD cards or serial Flash to an external DAC. The 16 KB SRAM buffers decoded audio frames, while the 64 KB Flash stores a small audio decoder (WAV, ADPCM, or simple MP3) plus UI logic. Sample rates up to 48 kHz at 16 bits are achievable through I2S with DMA offload. Trade-off versus PIC32MX450: this part has no integrated audio DAC, so designers must add an external codec such as the MCP4725 or PCM5102A. Typical applications include talking kiosks, museum exhibits, and budget Hi-Fi streamer endpoints.
Được đề xuất
Industrial Sensor Hub with PMP
The PIC32MX430F064LT-V/TL's 8-bit PMP (Parallel Master Port) can drive character LCDs, TFT displays, or external memory. Combined with the dual I2C buses, designers can aggregate up to 8 sensor nodes per bus while displaying real-time data on a graphics panel. The 80 MHz core supports modbus RTU or CANopen protocol stacks via UART/SPI, making this MCU a compact industrial sensor hub. The 'V' temperature grade (-40C to +105C) supports factory floor installations. Trade-off: only 16 KB RAM limits the number of concurrent sensor streams; designers handling more than 16 sensors should step up to PIC32MX460F256L.
Được đề xuất
USB-OTG Device Charger / Power Bank
With USB-OTG full-speed, the PIC32MX430F064LT-V/TL can implement portable device chargers, power bank controllers, or USB Type-A output ports. The MCU reads USB DP/DM lines to negotiate charging profiles (USB BC 1.2, Apple, Samsung) and drives MOSFET gate signals via PWM for buck/boost regulation. The CTMU can be repurposed to measure current via shunt resistor, providing coulomb counting for accurate remaining-capacity display. Trade-off: the PIC32MX430 does not have native Type-C PD, so for USB-PD applications designers should use the PIC32MX250F256L with FUSB302 firmware or pair this MCU with an external FUSB302 Type-C controller.
Được đề xuất
Small Graphical HMI with Color TFT
The PMP peripheral drives small 3.5-inch or 4.3-inch TFT displays (HX8257, ILI9341 clones), making this MCU a low-cost platform for graphical HMIs in appliances, HVAC controls, and access-control terminals. The 80 MHz core can refresh QVGA frames using 8-bit PMP in single-buffered mode, and the DMA offloads color fill operations. The 64 KB Flash stores UI screens, fonts, and bitmaps; the 16 KB SRAM supports 1 framebuffer at QVGA color depth 16-bit. Trade-off: not all 124 pins are bonded out to GPIO on this device, so designers wanting a large TFT interface should consider PIC32MX460F256L.

Ghi chú thiết kế
The 124-pin VTLA package has an exposed thermal pad that must be soldered to a continuous ground plane for both electrical ground and thermal dissipation. According to Microchip's VTLA-124 land pattern specification, the EP land should be at least 50% the area of the package body, with thermal vias on a 0.4 mm pitch. Decouple each VDD/VSS pair with a 100 nF ceramic capacitor placed within 3 mm of the pins, and add a single 4.7 uF bulk cap near the analog AVDD/AVSS pair. Keep USB DP/DM trace lengths under 25 mm and 90 ohms differential to pass USB compliance.
Avoid the common pitfall of leaving the VUSB3V3 pin floating when USB is not used; this pin must be tied to VDD through a ferrite bead or shorted to VDD via 0 ohm resistor, otherwise the USB PHY remains powered and increases quiescent current. Another frequent issue is incorrect configuration of the JTAG/Trace pins - the PIC32MX430F064L shares PGECx/PGEDx with TCK/TMS, so the debugger must be wired to dedicated pins (typically PGEC1/PGED1) and not remapped. Always enable the JTAG Disable fuse for production to recover those GPIO pins.
Use a low-dropout LDO with at least 200 mA headroom for the PIC32MX430F064LT-V/TL. The MCU can draw 75 mA peak when the USB and ADC run concurrently. Add a 10 uF input capacitor to the LDO and a 1 uH ferrite between LDO output and the MCU's VDD pins to suppress switching noise from upstream regulators. The AVDD pin should be filtered separately through a small ferrite or pi-filter to avoid coupling ADC noise into the digital supply.
