PIC32MX430F064HT-I/MR - 100MHz 32-bit MCU 64KB Flash | Microchip
MPN: PIC32MX430F064HT-I/MR ✓ AktifPIC32MX430F064HT-I/MR Ringkasan
A 32-bit microcontroller (MCU) is a single-chip processor that integrates a CPU core, program and data memory, and a configurable set of peripheral interfaces (timers, ADC/DAC, communication buses, I/O). In the broader taxonomy, MCUs sit below microprocessors (MPU) in integration and above discrete logic in capability, forming the lowest decision-making layer of embedded systems. The PIC32MX family specifically targets cost-sensitive 32-bit designs where MIPS instruction set familiarity, USB connectivity, and PIC ecosystem software (MPLAB X, Harmony) matter more than raw core-mark scores.
Key feature highlights include 64 KB single-cycle Flash with live-update support, 16 KB SRAM, USB-OTG full-speed with internal transceiver, two SPI/I2S ports, two I2C and two UART interfaces, five 16-bit timers, a 10-bit 1 Msps ADC with up to 28 channels, a charge time measurement unit (CTMU) for capacitive touch and time-of-flight, parallel master port (PMP) for graphics or external memory, and a hardware DMA controller with up to eight channels. A configurable interrupt controller with five priority levels supports deterministic real-time response.
Architecturally, the M4K core implements a 5-stage pipeline with single-cycle MAC and hardware multiply/divide, executes most instructions in one cycle, and supports MIPS16e code compression for denser Flash usage. The 16 KB SRAM is split into 4 KB tightly-coupled core RAM plus 12 KB system RAM. A 4 KB instruction cache pre-fetches Flash lines, hiding Flash latency. On-chip voltage regulation produces a 1.8 V core domain from the external 2.3-3.6 V VDD, eliminating the need for an external LDO on most designs. Peripheral DMA offloads SPI, UART, I2C, ADC, and PMP transfers, freeing the core for application logic.
Typical applications include USB peripherals (HID, CDC, mass storage, audio class), capacitive-touch user interfaces using CTMU, low-cost graphics HMI via PMP and an external LCD controller, industrial sensor nodes with on-chip ADC, and consumer audio docks using I2S. The wide 2.3-3.6 V supply and -40 C to +85 C industrial temperature range also make it suitable for factory-floor equipment.
When designing with this device, pay attention to the 64-pin VQFN land pattern: thermal pad soldering and via stitching are critical for achieving the rated thermal resistance. Decouple every VDD/VSS pair with a 100 nF X7R placed within 2 mm of the pin, and add a 4.7 uF bulk capacitor near the VBUS line when the USB-OTG transceiver is used. Programming uses MPLAB X IDE with the ICD 3 or PICkit 4.

Aplikasi Umum
PIC32MX430F064HT-I/MR cocok untuk 6 aplikasis: USB HID Peripheral (Keyboard, Mouse, Custom), Capacitive Touch User Interface, Low-Cost Graphics HMI with External LCD Controller, Industrial Sensor Node with Modbus RTU, USB Audio Class Device (Headset, Speaker Dock), Consumer USB Mass Storage / MIDI Device.
USB HID Peripheral (Keyboard, Mouse, Custom)
The PIC32MX430F064HT-I/MR's integrated USB-OTG full-speed controller with on-chip transceiver and dedicated DMA channels makes it a strong fit for USB HID peripherals such as keyboards, mice, custom joysticks, and HID-class industrial input devices. The 100 MHz MIPS32 M4K core provides more than enough headroom to handle HID report generation, debouncing, and LED animation, while the 64 KB Flash accommodates USB stack plus application code. Designers typically use Microchip's MPLAB Harmony USB Device stack, which requires only a 4 MHz crystal plus 12 MHz PLL configuration. The 5 V-tolerant I/O simplifies matrix-scanning interfaces to legacy keyboards, and the DMA-offloaded endpoint memory leaves CPU cycles free for the application layer.

Capacitive Touch User Interface
The on-chip CTMU (Charge Time Measurement Unit) with hardware-assisted timing enables precise capacitive touch sensing on up to 28 channels using the same pins as the ADC. The PIC32MX430F064HT-I/MR runs Microchip's mTouch CVD or SLD library to implement buttons, sliders, and proximity sensors, all without external touch ICs. The 16 KB SRAM is sufficient for a 16-channel touch panel plus USB status reporting. Compared with dedicated touch ICs, integrating CTMU saves $0.30-0.60 in BOM cost at modest volumes. Industrial temperature grade supports appliance front-panel designs in kitchen and HVAC equipment.

Low-Cost Graphics HMI with External LCD Controller
The PIC32MX430F064HT-I/MR exposes a Parallel Master Port (PMP) that drives external LCD controllers such as the SSD1963 or RA8875 for QVGA/WQVGA TFT panels in 3.5-5 inch HMIs. The PMP supports 8/16-bit interfaces with dedicated DMA channels, freeing the core to handle button inputs, USB commands, and Modbus polling. 64 KB Flash fits typical HMI applications: menu system, fonts in external SPI Flash, USB firmware update, and Modbus slave stack. The wide 2.3-3.6 V supply simplifies direct 3.3 V panel backlight drive, and the 49 I/O lines support keypads and rotary encoders without external I/O expanders.

Industrial Sensor Node with Modbus RTU
For industrial 4-20 mA loop powered or Modbus RTU sensor nodes, the PIC32MX430F064HT-I/MR delivers enough computation for sensor linearization, moving-average filtering, and Modbus protocol handling. Its 10-bit 1 Msps ADC with up to 28 channels supports multi-sensor conditioning through external muxes, and the 5 V-tolerant UART interfaces directly to RS-485 transceivers such as the MAX3485 or ISL3179. Industrial -40 C to +85 C temperature grade and wide 2.3-3.6 V supply tolerate real factory-floor environments. The 16 KB RAM accommodates Modbus buffers and floating-point filter math using the single-precision math library.

USB Audio Class Device (Headset, Speaker Dock)
The PIC32MX430F064HT-I/MR supports USB Audio Class 1.0 device mode and exposes two I2S ports for connecting to external 16/24-bit DACs or ADCs, making it suitable for USB headsets, speaker docks, and digital microphones. The 100 MHz core is sufficient to handle USB isochronous transfers at 48 kHz stereo with underrun protection. Designers typically pair it with a stereo DAC like the PCM5101A or a codec such as the SGTL5000 for I2S audio playback. CTMU can also implement push-button playback control on the same die. Total BOM cost for a USB-to-I2S adapter lands under $4 in modest volumes.

Consumer USB Mass Storage / MIDI Device
The integrated USB-OTG controller and dual SPI ports make the PIC32MX430F064HT-I/MR a good fit for USB Mass Storage or USB-MIDI device designs when paired with external SPI Flash or SD cards. The PMP can also interface to SD cards directly in SD mode for higher throughput. 64 KB Flash accommodates the USB stack plus FAT12/16/32 file system plus application logic. DMA channels handle the bulk transfer between USB endpoint memory and the SD card sector buffers, minimizing CPU overhead. The 5 V-tolerant I/O allows direct connection to MIDI DIN-5 jacks through opto-isolated receivers.

Diferensiator Kunci
- Lowest-cost USB-OTG MCU in 64 KB Flash tier (vsPIC32MX350F128H-I/MR)
- MIPS32 M4K ecosystem maturity vs Cortex-M0 learning curve (vsPIC32MX250F256H-I/MR)
- Industrial temperature range with CTMU included (vsPIC32MX330F064H-I/MR)
Catatan Desain
The 64-pin VQFN package has an exposed thermal pad (pin 65) that MUST be soldered to a ground plane with at least 8 thermal vias on a 1.2 mm pitch to achieve the rated 22 C/W thermal resistance. Without proper pad soldering, junction temperature rises 30-40% higher under identical load. Place a 4-layer PCB with dedicated ground plane; 2-layer designs suffer EMI on USB-OTG signal integrity due to insufficient return path.
Decouple every VDD/VSS pair (5 pairs total on this package) with a 100 nF X7R ceramic capacitor placed within 2 mm of the pin footprint. Add a single 4.7 uF X5R bulk capacitor near the package center. For USB-OTG designs, place an additional 100 uF bulk capacitor within 5 mm of the VBUS pin to handle the 500 mA inrush transient required by USB 2.0 specification.
Route USB D+/D- as a 90 ohm differential pair with matched length within 150 mil, and place the 15 kohm pulldowns on D+ and D- within 2 mm of the device pins (for full-speed device mode). Keep crystal traces within 5 mm of the OSC1/OSC2 pins and surround them with a ground guard ring. Avoid running digital signals under the crystal traces or USB pair to minimize coupling.
Do not configure the on-chip 1.8 V regulator's VCAP/VDDCORE pin as a GPIO - it is internally connected to the core logic. Floating the VCAP pin causes core voltage instability and random resets. Also ensure the MCLR pin has a 10 kohm pullup to VDD; floating MCLR causes unintended resets in noisy environments. The VUSB pin must be decoupled with 100 nF plus 4.7 uF for stable USB transceiver operation.
