PIC32MX330F064HT-V/RG 概要
A 32-bit microcontroller (MCU) is a single-chip processor with on-chip Flash program memory, SRAM data memory, and integrated peripherals such as timers, UARTs, SPIs, I2C, ADC, and PWM. The PIC32MX3/4 family occupies the performance mid-tier of the Microchip PIC32 line: ARM Cortex-M-class alternatives such as STM32F1 or NXP LPC1768 typically use Harvard M-architecture for similar DMIPS/$M. The PIC32MX M4K core delivers up to 150 DMIPS at 120MHz and uses a five-stage pipeline with hardware multiply/divide, supporting 32-bit MIPS instructions.
Key features of the PIC32MX330F064HT include: 64KB Flash program memory, 16KB SRAM, two SPI/I2S, two I2C, two UART, USB 2.0 full-speed OTG, 10-bit ADC with up to 16 channels, five 16-bit timers/counters, and parallel master port (PMP). The 64-pin VQFN (RG) package with exposed pad provides a thermal resistance suitable for industrial -40C to +105C operation. The 'H' suffix denotes 64KB Flash with USB; the 'T' suffix denotes Tape and Reel.
Architecture depth: PIC32MX uses a 5-stage pipeline, single-cycle multiply, hardware divide, and bit-banding for atomic bit manipulation. The M4K core supports MIPS16e code compression, reducing Flash footprint by ~30%. USB OTG enables host or device mode with integrated PHY; PMP can interface to external parallel buses, graphics LCDs, or FPGA.
Typical applications include industrial control (USB HMI, sensor hubs), low-cost audio devices (USB speakers, MIDI), home automation (HA-BUS bridges, smart thermostats), USB peripherals (barcode scanners, custom HID), and more. The wide operating range and rich peripherals suit automotive aftermarket and harsh-environment designs.
Design consideration: route the exposed pad (EP) to a solid ground copper pour with at least 8 thermal vias for heat dissipation. Decouple VDD/VUSB with 100nF ceramic as close to the IC pins as possible; for USB use a 10uF bulk plus ESD array (such as USBLC6-2SC6A).

主な用途
PIC32MX330F064HT-V/RG の用途: 6 件s: USB Human Interface Devices (HID), Industrial Sensor Hub / Data Logger, USB Audio Class Device (Speaker / Headset), Home Automation Gateway Bridge, Automotive Aftermarket Display Module, Custom USB Test and Measurement Instrument.
USB Human Interface Devices (HID)
The PIC32MX330F064HT-V/RG is well suited for USB HID devices such as custom keyboards, mice, game controllers, and barcode readers thanks to its integrated USB 2.0 full-speed OTG controller with on-chip PHY that eliminates external USB transceivers. The 80 MHz MIPS32 M4K core delivers ample processing headroom for HID report parsing, debouncing, and LED animation, while 16 KB SRAM handles HID buffers and USB endpoint descriptors. The 64 KB Flash is sufficient for Microchip's USB stack, HID class driver, and application logic with MIPS16e code compression. Reference the Microchip MLA (Microchip Libraries for Applications) USB device stack for production-ready HID firmware.
おすすめ
Industrial Sensor Hub / Data Logger
The PIC32MX330F064HT-V/RG serves as a multi-sensor aggregation node in industrial sensor hubs: two I2C buses interface up to 30 sensors each (temperature, pressure, humidity), two SPI buses connect high-speed ADCs or accelerometers, and the 10-bit ADC with 16 channels reads analog sensors directly. The wide -40C to +105C operating range suits factory floor and process-control environments. The 16 KB SRAM can buffer several minutes of timestamped sensor data before forwarding to a host via UART or USB. Pair the MCU with an external FRAM or SPI Flash for non-volatile log storage when 64 KB internal Flash is exhausted.
おすすめ
USB Audio Class Device (Speaker / Headset)
The PIC32MX330F064HT-V/RG powers USB speakers, USB headsets, and USB microphone designs using its USB 2.0 FS OTG plus dual I2S/PCM interfaces. The MCU streams 16-bit 48 kHz stereo audio from USB isochronous endpoints to an external DAC or codec over I2S, with DMA ensuring glitch-free playback without CPU intervention. Microchip's USB Audio Class 1.0 firmware library supports speaker, headphone, and microphone topologies. The 64 KB Flash holds the USB stack plus audio class driver; 16 KB SRAM buffers USB packets and audio samples. The exposed pad provides thermal dissipation for sustained audio streaming.
おすすめ
Home Automation Gateway Bridge
The PIC32MX330F064HT-V/RG operates as a bridge between low-speed home automation buses (Zigbee, Z-Wave, BLE) and a Wi-Fi/Ethernet host. Two UARTs connect to wireless modules transceivers, two SPI/I2S channels interface to RF transceivers or displays, and USB OTG links to the host processor for configuration. The 80 MHz core handles protocol conversion, message queuing, and OTA update verification. The -40C to +105C range covers outdoor enclosures and uncontrolled indoor environments. Wide 2.5V/3.3V operation supports direct battery or USB-powered operation.
おすすめ
Automotive Aftermarket Display Module
The PIC32MX330F064HT-V/RG drives automotive aftermarket accessories such as OBD-II dongles, HUD projectors, and gauge clusters. USB OTG interfaces the device to a phone or head unit, the PMP (parallel master port) drives small TFT LCD displays without an external graphics controller, and two SPI buses link to accelerometers for tilt compensation. The -40C to +105C V-grade temperature rating handles under-dash thermal conditions. The wide input voltage tolerance supports 12V automotive supply rails with external regulation.
おすすめ
Custom USB Test and Measurement Instrument
The PIC32MX330F064HT-V/RG builds USB-connected test instruments such as USB oscilloscope probes, logic analyzers, and digital multimeters. USB OTG streams 10-bit ADC samples to a PC host at up to 1 Msps, while two UARTs handle serial protocol decode. The 16 KB SRAM buffers sample bursts before USB transmission, and 64 KB Flash stores calibration constants and USB descriptors. The exposed pad VQFN64 provides the thermal headroom needed for sustained ADC sampling. Reference Microchip's USB CDC class firmware for virtual COM port instruments.

設計ノート
Estimated: The 64-pin VQFN EP package dissipates heat through the exposed pad (pin 65). For continuous USB streaming or sustained ADC sampling at full 80 MHz, solder the EP to a PCB pad of at least 25 mm^2 copper area connected to ground, with 8-12 thermal vias (0.3 mm drill, 0.5 mm pitch). Without proper EP soldering, junction temperature may rise 30-40 C above ambient at 100% CPU load, exceeding the +105C maximum. Reference Microchip's 'PIC32 Family Reference Manual, Packaging and Thermal Considerations' for layout guidance.
Place a 100 nF ceramic decoupling capacitor as close as possible to each VDD pin (pins 28 and 42). Add a single 4.7 uF to 10 uF bulk capacitor near the MCU. For USB applications, the VUSB pin (when used) requires a 100 nF and 4.7 uF capacitor pair per the USB 2.0 specification. Avoid running the analog and digital supplies from the same regulator if the ADC is used; split VDD into VDD and AVDD rails with separate filtering for best ADC accuracy.
Route the 80 MHz system clock traces with controlled impedance (50 ohm microstrip or stripline) and keep them as short as possible. The USB D+/D- traces must be 90 ohm differential, routed symmetrically, and length-matched within 150 mils. Use a ground keep-out under the crystal traces and place the 12 MHz or 24 MHz crystal within 5 mm of the OSC1/OSC2 pads. Avoid routing sensitive analog signals (ADC inputs) parallel to digital switching signals.
Do not omit the MCLR pull-up resistor (typically 10 kohm to VDD); missing MCLR can prevent normal operation or cause erratic resets. Configure unused I/O pins as outputs driven low (not high-impedance inputs) to minimize supply current. The PGECx/PGEDx programming/debug pins should be left accessible for in-circuit programming; do not place them on internal-only nets. Avoid using the 'L' suffix variant (PIC32MX330F064L) if USB is required - the 'L' parts lack USB.
