PIC32MX430F064L-I/PT - 80MHz 32-bit MCU, 64KB Flash, USB-OTG | Microchip
MPN： PIC32MX430F064L-I/PT ✓ 啟用中PIC32MX430F064L-I/PT 概覽
An MCU (microcontroller) is a single-chip computer integrating a CPU core, program memory (Flash), data memory (SRAM), and a mix of peripherals such as timers, ADC, communication controllers, and GPIO. The PIC32MX3/4 line sits in Microchip's mid-range 32-bit portfolio between the smaller PIC32MX1/2/5 and the higher-end PIC32MX5/6/7 families, targeting USB-enabled embedded designs that need audio, graphics, and touch (HMI) front ends. Within this taxonomy the PIC32MX430F064L belongs to the 100-pin USB-equipped sub-family.
Key features include a USB 2.0 Full-Speed OTG controller, two I2S/SPI modules for codec and serial audio, Peripheral Pin Select (PPS) for flexible pin mapping, a Parallel Master Port (PMP) for graphics interfaces, a 10-bit 1 Msps ADC with up to 28 inputs, a Charge Time Measurement Unit (CTMU) for capacitive touch, and 5 16-bit timers plus an RTCC. The I-grade suffix specifies an industrial -40C to +85C operating range at 80 MHz core, and the operating voltage is 2.3 V to 3.6 V.
The architecture combines a 5-stage MIPS32 M4K pipeline with single-cycle hardware multiply/divide and a tightly-coupled prefetch module, giving the part competitive DSP-like throughput for the cost. The 100-pin TQFP footprint is shared with siblings in the same family, simplifying PCB layout reuse across memory and pin-count variants.
Typical applications include USB audio interfaces, Human-Machine Interface (HMI) panels with graphics LCD and capacitive touch, industrial control with USB host/device logging, and low-cost 32-bit upgrades of legacy PIC24/PIC32 designs. The combination of USB OTG, I2S, and PMP makes it especially useful for consumer audio docks and small appliances with color displays.
When designing with this part, allocate the four ICSP pairs (PGEC1/PGED1, PGEC2/PGED2) early; any pair can be used for programming but both signals of the chosen pair must be routed together, and all VDD/VSS pins must be decoupled. Plan analog and digital ground partitioning before the USB DP/DM traces to keep the differential pair impedance at 90 ohm.

典型應用
PIC32MX430F064L-I/PT 適用於 6 應用s: USB Audio Device with I2S Codec, HMI Panel with Color LCD and Capacitive Touch, Industrial USB Host Data Logger, Consumer Appliance with Touch Front Panel, USB HID Peripheral (Keyboard/Mouse/Gamepad), Portable Medical Point-of-Care Device.
USB Audio Device with I2S Codec
The PIC32MX430F064L-I/PT is a strong fit for USB audio interfaces (USB headphones, USB DACs, USB microphones) because it integrates a USB 2.0 Full-Speed OTG controller together with two I2S/SPI modules on the same die. The I2S lines feed an external audio codec such as the TI PCM2707 or the Microchip LAN9353, while the USB OTG controller handles the asynchronous USB isochronous audio stream at full-speed (12 Mbps). The 16 KB SRAM is sufficient for double-buffered audio at 48 kHz/16-bit, and PPS allows flexible remapping of the I2S SCK/WS/SD lines. Compared to a discrete USB + DSP solution, the PIC32MX430F064L reduces BOM by removing the external USB PHY and codec glue logic.
推薦
HMI Panel with Color LCD and Capacitive Touch
For Human-Machine Interface (HMI) panels with a small color TFT and capacitive touch buttons, the PIC32MX430F064L-I/PT provides a Parallel Master Port (PMP) for direct connection to ILI9341/SSD1963-style LCD controllers and a Charge Time Measurement Unit (CTMU) that supports up to 28 capacitive touch channels without an external touch IC. The 64 KB Flash accommodates a graphical menu stack, and PPS lets you reassign PMP data lines around PCB routing constraints. The 80 MHz MIPS M4K core renders a 320x240 QVGA panel comfortably while leaving CPU margin for USB diagnostics. Compared to a Cortex-M0 HMI solution, the integrated PMP saves an external bus latch.
推薦
Industrial USB Host Data Logger
The PIC32MX430F064L-I/PT fits industrial USB host data loggers that read USB flash drives or USB barcode scanners, thanks to the on-chip USB OTG controller operating in host mode. Engineers commonly pair it with a CH376S or Microchip USB host stack to mount FAT32 file systems on removable media. The 10-bit 1 Msps ADC with up to 28 channels logs analog sensor data into the 16 KB SRAM ring buffer, and the RTCC provides time-stamping across power cycles. The 2.3-3.6 V supply range tolerates industrial 24 V -> 3.3 V buck rails. Industrial control benefits from the -40C to +85C I-grade operating range.
推薦
Consumer Appliance with Touch Front Panel
For consumer appliances (coffee machines, smart kettles, white goods) needing a low-cost 32-bit MCU with capacitive touch and a small color display, the PIC32MX430F064L-I/PT pairs the CTMU touch peripheral with PMP-driven TFT graphics. The 100-pin TQFP leaves ample GPIO for motor PWM, thermistor ADC inputs, and buzzer drivers. Compared to a discrete touch-IC + 8-bit MCU architecture, integrating CTMU and PMP into the MCU cuts the BOM by 1-2 USD per board. The 80 MHz MIPS core runs a FreeRTOS or Microchip Harmony scheduler with comfortable margin.
推薦
USB HID Peripheral (Keyboard/Mouse/Gamepad)
The PIC32MX430F064L-I/PT is well-suited to USB HID peripherals such as keyboards, mice, gamepads, and barcode scanners because the integrated USB 2.0 Full-Speed OTG controller directly handles HID-class descriptors without an external PHY. The PPS peripheral mapping lets the engineer assign USB interrupt, scan-matrix GPIOs, and LED PWM outputs to almost any pin, simplifying PCB layout. The 16 KB SRAM is enough for USB HID report FIFOs and debounce state machines. Compared to 8-bit PIC16/PIC18 with external USB, the 32-bit MIPS core reduces firmware complexity for composite HID devices.
推薦
Portable Medical Point-of-Care Device
In portable medical point-of-care devices (glucose meters, pulse oximeters, low-cost diagnostic tools), the PIC32MX430F064L-I/PT's 10-bit 1 Msps ADC and CTMU support both sensor readout and capacitive touch UI on a single die. USB OTG enables direct connectivity to a host PC for data upload or battery charging. The 2.3-3.6 V operating range suits single-cell Li-ion (3.0-4.2 V) plus LDO designs. Compared to discrete ADC + touch-IC + 8-bit MCU stacks, integration reduces PCB area and bill of materials for cost-sensitive medical OEMs.

主要差異化特點
- USB OTG plus two I2S in a single 100-pin TQFP at this price point (對比PIC32MX330F064L-I/PT)
- Same die across -I and -V grades for design reuse (對比PIC32MX430F064L-V/PT)
- PMP for direct TFT interface without external bus latch (對比PIC32MX270F256L-I/PT)
設計說明
Decouple every VDD/VSS pair with 100 nF X7R ceramic placed as close to the pin as possible, and add a bulk 4.7 uF or 10 uF tantalum at the regulator output. The PIC32MX430F064L has multiple VDD pins (pins 2, 60, and others on the 100-pin TQFP); each must be individually bypassed. Connect AVDD and VDD to the same 3.3 V rail but isolate the analog ground (AVSS) with a ferrite or 0 ohm resistor to keep ADC reference noise under 1 LSB at the 10-bit/1 Msps rate.
Route the USB D+ and D- lines as a 90 ohm differential pair with length-matched traces (delta < 150 mil) and keep them away from switching nodes. Place the VBUS sense resistor network within 5 mm of pin 55. The 32.768 kHz SOSC crystal (pins 51/52) should be guarded with a ground ring and the load capacitors placed within 3 mm of the pins to avoid oscillator startup failures.
PPS inputs (RPx) are inputs only - output functions require high-speed RPx pins selected via the PPS Output group registers; not every pin can route every peripheral. Always configure PPS before enabling the peripheral, otherwise the peripheral will not appear on the chosen pin. The I2C SCL1/SDA1 pins (75/76) have fixed mapping - do not try to remap them. JTAG and ICSP pins must not be repurposed in production firmware if you intend to use boundary-scan or ICSP re-flashing.
Estimated: at 80 MHz with full peripheral activity (USB + ADC + I2S), core current draw is approximately 60 mA from 3.3 V, dissipating ~200 mW. The TQFP-100 package has a theta_JA of approximately 40 C/W on a 4-layer JEDEC test board, giving a 8 C rise above ambient - well within the 85 C I-grade limit. No heatsink is required, but a copper ground pour under the package reduces junction temperature further.
