PIC32MX430F064LT-I/TL 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of on-chip peripherals such as timers, communication interfaces, and analog-to-digital converters. Within the broader PIC32MX3/4 family hierarchy, the PIC32MX430F064L sits as a cost-optimized 32-bit tier that bridges 8/16-bit PIC microcontrollers and the higher-end PIC32MZ family, designed for embedded applications requiring genuine 32-bit performance at low BOM cost.
Key features include the MIPS32 M4K 32-bit RISC core delivering 1.56 DMIPS/MHz (up to 125 DMIPS), 64 KB Flash with 20-year retention, 16 KB SRAM, two I2S/SPI interfaces, two I2C, two UART, USB-OTG with integrated PHY, a 10-bit ADC with up to 28 input channels, a Charge Time Measurement Unit (CTMU), and up to five 16-bit timers. The integrated DMA controller and 8-bit parallel master port (PMP) reduce CPU load for high-throughput peripherals, while the on-chip 8 MHz internal oscillator supports system operation without an external crystal.
Typical applications include USB peripherals, industrial control panels, low-cost graphical user interfaces (GLCDs), consumer audio with I2S, sensor hubs, and home appliances. The 80 MHz core with single-cycle multiply gives the throughput needed for closed-loop motor control, USB audio class devices, and PID-based process control where 8-bit MCUs lack the headroom.
A key design consideration is the 124-pin VTLA exposed-pad package - the EP pad MUST be soldered to a continuous copper ground plane for both thermal dissipation and electrical reference. For cost-sensitive applications, the same family offers smaller Flash options (PIC32MX430F256L, PIC32MX430F128L) in the same VTLA-124 footprint, enabling drop-in scaling across product lines.
This page synthesizes live distributor pricing, pin-compatible drop-in alternatives from the same PIC32MX3/4 family, and practical hardware/PCB design notes that are not present in the manufacturer datasheet, giving engineers a one-stop reference for sourcing, selection, and design-in decisions.

主な用途
PIC32MX430F064LT-I/TL の用途: 6 件s: USB HID / CDC Peripheral Devices, Industrial Control Panels with GLCD, USB Audio Class (USB Headphones / Headsets), Home Appliance Sensor Hubs, Low-Cost Graphical Touch User Interfaces, Closed-Loop Motor Control (FOC / PID).
USB HID / CDC Peripheral Devices
The PIC32MX430F064LT-I/TL's integrated USB 2.0 Full-Speed OTG PHY with on-chip transceiver makes it ideal for USB Human Interface Devices (HID), Communications Device Class (CDC) virtual COM ports, and custom vendor-class peripherals. The 80 MHz MIPS32 M4K core sustains USB polling and HID report generation with low interrupt latency, while the 64 KB Flash holds Microchip's USB stack plus application code. The integrated PHY eliminates the BOM cost of an external USB chip; only 27-ohm series resistors and a 1.5 kohm pull-up on D+ are needed. Designers should use the Microchip MPLAB Harmony USB framework for HID/CDC class compliance, and add ESD protection (USBLC6-2SC6 or equivalent) on the USB connector.
おすすめ
Industrial Control Panels with GLCD
The PIC32MX430F064LT-I/TL's 8-bit Parallel Master Port (PMP) drives graphical LCDs (GLCDs) directly without an external controller, while the 64 KB Flash supports menu systems, asset tracking firmware, and Modbus RTU stacks. The 80 MHz core refreshes QVGA GLCDs at acceptable frame rates when paired with the PIC32 GLCD library. Five 16-bit timers drive PWM-controlled LED backlights, buzzers, and relay sequencing. The on-chip 10-bit ADC with 28 channels reads panel potentiometers, NTC thermistors, and 4-20 mA loopback sensors simultaneously. The VTLA-124 package enables compact HMI panel designs, with the exposed pad providing thermal dissipation for backlight driver MOSFETs on the same PCB.
おすすめ
USB Audio Class (USB Headphones / Headsets)
The PIC32MX430F064LT-I/TL implements USB Audio Class 1.0 devices with the I2S peripheral streaming stereo 48 kHz audio to an external DAC like the PCM5102A or to a Class-D amplifier with I2S input. The integrated USB OTG PHY handles full-speed USB audio at 48 kHz / 16-bit without external chips, while the DMA controller moves I2S samples to/from memory without CPU load. The 16 KB SRAM is sufficient for short audio buffering; designers needing larger buffers or simultaneous USB + I2S paths can drop in PIC32MX450 or PIC32MX370 variants in the same VTLA-124 footprint. Add a low-jitter crystal on the REFCLKI pin for clean I2S clocking.
おすすめ
Home Appliance Sensor Hubs
The PIC32MX430F064LT-I/TL is well suited for sensor hubs in white goods (refrigerators, washing machines, dishwashers) where it aggregates temperature, humidity, door-switch, and motor-current sensor inputs via the 28-channel 10-bit ADC, then drives a display and serial communication to the main controller. The CTMU (Charge Time Measurement Unit) enables capacitance-touch user interfaces (buttons, sliders) without an external touch IC, reducing BOM cost. Two UART channels bridge to Wi-Fi modules (e.g., RNWF02) and to the main appliance MCU, while the 80 MHz core handles Modbus / appliance protocol stacks. The industrial -40C to +85C temperature grade covers appliance environments.
おすすめ
Low-Cost Graphical Touch User Interfaces
For low-cost graphical touch interfaces, the PIC32MX430F064LT-I/TL combines the 8-bit PMP driving a TFT or GLCD panel, the CTMU for touch-button scanning, and the 80 MHz core running lightweight emWin/MPLAB Harmony graphics stacks. With 64 KB Flash, designers can deliver small monochrome or 16-bit color UIs with up to QVGA resolution. Designers targeting richer UIs (full WVGA, multi-language fonts) should select the PIC32MX370F512LT-I/TL with 512 KB Flash in the same VTLA-124 footprint. Add an external SPI flash (e.g., SST26VF016B) for asset data storage without crowding the internal Flash.
おすすめ
Closed-Loop Motor Control (FOC / PID)
The PIC32MX430F064LT-I/TL drives BLDC and PMSM motors in low-cost FOC and PID loops, leveraging its 80 MHz MIPS32 M4K core (1.56 DMIPS/MHz), five 16-bit timers with PWM output compare, and the 28-channel 10-bit ADC for back-EMF and current sensing. The DMA controller moves ADC samples into memory while the CPU executes the FOC math at 20-40 kHz loop rates. The integrated USB enables real-time tuning over USB CDC, eliminating external debug UARTs. The 64 KB Flash holds MC-PMSM or simple FOC libraries from Microchip; upgrade to PIC32MX430F256LT-I/TL for sensorless FOC stacks requiring more code space. Ensure adequate bulk capacitance on VMOT to absorb motor-controller switching transients.

設計ノート
Estimated: The 124-pin VTLA (9x9 mm) exposed-pad package requires the center thermal pad to be soldered to a continuous ground copper plane on the top layer for both thermal dissipation and electrical reference. The datasheet recommends a 4x4 to 6x6 via-array (0.3 mm drill, 0.5 mm pad) stitching the EP to inner ground planes. Without a properly soldered EP, junction temperature can rise 15-20 C above ambient at full 80 MHz CPU + USB load, potentially triggering thermal shutdown or long-term reliability drift.
Place a 10 uF bulk + 0.1 uF ceramic decoupling pair on each VDD/VSS pair, located within 5 mm of the package pin. The PIC32MX430 has multiple VDD pins (VDD, VDDIO, VBUS, etc.) - the family datasheet Section 'Electrical Characteristics' lists each rail's recommended decoupling. Use a low-ESR ceramic (X7R 10 uF 6.3V 0805) for high-frequency noise suppression; the internal 1.8V core LDO requires its own 4.7 uF + 0.1 uF pair on the VCAP pin. Insufficient decoupling is the #1 cause of USB enumeration failures and brown-out resets.
The USB OTG PHY requires precise 48 MHz clocking for Full-Speed compliance. Many low-cost designs use the internal 8 MHz oscillator with PLL, but USB jitter is sensitive to PLL settings - configure the 96 MHz PLL post-divider to produce exactly 48 MHz with the SPLL field bits per the family reference manual DS61109. Add a series 27-ohm resistor on each USB D+/D- line as close to the MCU as possible for EMI control, and route D+/D- as a 90-ohm differential pair on the PCB. Omitting these can yield USB compliance failures at the EMI chamber or erratic device enumeration.
Estimated: Route the analog ADC inputs (AN0-AN27) away from digital switching traces and from the USB D+/D- differential pair; cross only at 90 degrees if needed. Add a separate analog ground (AGND) island tied to the main GND at a single point under the MCU, and place the ADC VREF+ decoupling cap within 3 mm of the VREF+ pin. For designs that mix 3.3V digital and analog (e.g., audio ADC + USB), consider using ferrite beads on the analog supply rail. This typically reduces ADC noise floor by 2-3 LSB on the 10-bit converter.
