PIC32MX320F064HT-40V/PT Visão geral
A microcontroller (MCU) is a single-chip computer integrating a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and on-die peripherals (ADC, timers, communication controllers). Within the broader taxonomy, a microcontroller is a type of embedded processor -> microprocessor -> semiconductor IC. The PIC32MX family bridges 8/16-bit PIC MCU designs to full 32-bit performance with MIPS architecture, while remaining compatible with MPLAB X IDE and the PIC32 peripheral library for migration from older PIC24/PIC32 projects.
Key specifications include 40 MHz core clock (50 MHz capable variants exist in the family), 64 KB Flash (64K x 8), 16 KB SRAM, a 10-bit 1 MSps ADC with up to 16 channels, two I2C, two SPI, two UART, a Parallel Master Port (PMP) for graphics/parallel memory, and a USB 2.0 Full-Speed On-The-Go transceiver. The 'V' suffix denotes the 2.3-3.6 V extended operating range, while 'H' denotes TQFP package, and 'T' suffix denotes Tape & Reel.
Typical applications include USB peripherals (HID, CDC, mass storage), low-cost graphical HMI with PMP-driven TFTs, industrial control with sensor acquisition via the 10-bit ADC, consumer appliances, and educational/development boards. The 64-pin TQFP footprint is breadboard-friendly and the part is supported by the MPLAB Harmony framework for rapid firmware development.
When designing, ensure the USB D+/D- traces are routed as a 90 ohm differential pair, place decoupling capacitors within 3 mm of every VDD/VSS pair, and leave the AVDD pin supplied from a ferrite-filtered analog LDO for clean ADC measurements. JTAG/ICSP programming headers should be reserved for in-field firmware updates.

Aplicações típicas
PIC32MX320F064HT-40V/PT é adequado para 6 aplicaçãos: USB HID / CDC / Mass Storage Device, Low-Cost Graphical HMI (PMP-driven TFT), Industrial Sensor Acquisition & Control, Consumer Appliance Control, Educational / Development Boards, USB Audio Class Device (Speaker/Headset).
USB HID / CDC / Mass Storage Device
The PIC32MX320F064HT-40V/PT is well suited for USB device peripherals such as custom HID controllers, CDC virtual COM ports, and USB mass storage devices. The on-chip USB 2.0 Full-Speed OTG transceiver eliminates the need for an external PHY, while 64 KB Flash comfortably fits the Microchip USB stack plus application logic, and 16 KB SRAM accommodates HID report buffers and MSC sector caches. The 40 MHz MIPS32 M4K core delivers deterministic USB frame timing at 1 ms SOF intervals. Place 15 kilohm pull-up resistors on D+, route the differential pair as 90 ohms, and bulk-cap the VUSB3V3 rail with 4.7 uF ceramic for stable bus-powered operation.
Recomendado
Low-Cost Graphical HMI (PMP-driven TFT)
The PIC32MX320F064HT-40V/PT drives small TFT displays through its Parallel Master Port (PMP), enabling low-cost graphical HMI panels for appliance control, instrument front panels, and simple industrial displays. The PMP supports 8-bit or 16-bit bus widths and address lines to external memory or registers, freeing the core from tight bit-banging. With 40 MHz MIPS32 M4K performance, the controller sustains 16 FPS updates on 320x240 QVGA panels. Use the DMA controller to background-load PMP frames and place 1 uF ceramic decoupling on every VDD/VSS pair. PIC32MX270F256B-V/SO is a Site MPN alternative when more Flash is required for large icon sets.
Recomendado
Industrial Sensor Acquisition & Control
For industrial sensor acquisition the PIC32MX320F064HT-40V/PT integrates a 10-bit ADC with up to 16 input channels, supporting analog readings from temperature, pressure, and current sensors at up to 1 MSps aggregate conversion rate. The -40V suffix extends the operating temperature to +105C, suitable for factory floor cabinets and outdoor enclosures. Pair the digital VDD with a dedicated LDO via ferrite bead for clean analog AVDD reference. DMA-driven ADC sampling offloads the core so it can manage control loops or Modbus comms. The 5 timers and 2 UART/SPI channels support multi-axis motion and fieldbus interfaces.
Recomendado
Consumer Appliance Control
The PIC32MX320F064HT-40V/PT fits consumer appliance control boards such as washing machine controllers, microwave oven HMIs, and HVAC thermostats where cost is critical and USB is a one-time programming interface. Its low 2.3 V minimum operating voltage supports direct battery connection, while 16 KB SRAM provides adequate buffer for HMI state and user settings. The Microchip MPLAB Harmony framework enables rapid firmware development with USB MSD bootloader support, simplifying field firmware updates. Pair with the PIC32MX230F064B-I/SP for lower-pin-count appliances.
Recomendado
Educational / Development Boards
The PIC32MX320F064HT-40V/PT appears on numerous educational development boards and hobbyist projects thanks to the breadboard-friendly 0.5 mm pitch TQFP package, abundant documentation, and free MPLAB X IDE with Harmony code configurator. USB OTG enables students to implement HID, CDC, and audio class devices in a single semester. Combined with the PICkit 3/4 in-circuit debugger and the MPLAB Code Configurator peripheral library, the learning curve from PIC16/18 to PIC32 is minimal. The 53 GPIO pins expose ample prototyping real estate for parallel buses, motor control, and sensor interfacing.
Recomendado
USB Audio Class Device (Speaker/Headset)
The PIC32MX320F064HT-40V/PT is capable of implementing a USB Audio Class 1.0 device, streaming 16-bit 48 kHz PCM audio from a host PC to a DAC. The 40 MHz MIPS32 M4K core delivers just enough throughput for full-duplex audio at 48 kHz with DMA-fed I2S-style output. 16 KB SRAM holds USB endpoint buffers and the audio sample ring buffer, while 64 KB Flash stores the USB audio class driver plus application code. Use an external I2S DAC such as a 24-bit stereo codec for audiophile-grade playback; the PIC32 only handles the USB protocol and I2S framing.

Principais diferenciais

- Extended -40C to +105C operating temperature (vs PIC32MX320F064H-40I/PT (industrial))
Notas de projeto
Estimated: at full 40 MHz operation with all peripherals enabled, the PIC32MX320F064HT-40V/PT typically draws 30-45 mA from the 3.3 V supply. Add a 4.7 uF bulk capacitor and 100 nF decoupling within 3 mm of every VDD/VSS pair. The AVDD pin should be sourced from a ferrite-filtered low-noise LDO (such as an MCP1700) to keep ADC readings clean, especially when the USB transceiver is active.
Route the USB D+ and D- signals as a 90 ohm differential pair with matched length, keeping them short and well-clear of switching nodes. Place the 15 kilohm pull-up on D+ close to the MCU D+ pin, and add a 1 uF X7R bypass on VUSB3V3 within 3 mm. The crystal oscillator traces (OSC1/OSC2) should be short, with the load capacitors placed within 5 mm of the MCU pins and the crystal case grounded for EMI suppression.
Do not confuse the PIC32MX320F064HT-40V/PT (TQFP package, Tape & Reel, V extended temp) with the -40I/PT or -40V/PT siblings - temperature grade and packaging differ. The PIC32MX320 requires a 1.8-3.6 V core voltage supply routed via the internal regulator; ensure the ENVREG pin is tied high for 3.3 V operation. For programming, the ICSP/ICD pins (PGD/PGC/MCLR) must be brought out to a debug header for in-circuit flashing.
Estimated: at ambient 25 C and 3.3 V Vdd, the 64-pin TQFP theta_JA is approximately 45 C/W. At full 40 MHz operation drawing 45 mA (149 mW dissipation), junction temperature rises ~7 C above ambient, well within the 105 C V-grade limit. For designs sealed in enclosures with restricted airflow, consider derating to 30 MHz or migrating to the PIC32MX274F256DT-I/PT 50 MHz family variant.
