PIC32MX320F064HT-80V/MR Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O into one device. The PIC32MX family occupies the 32-bit performance tier of Microchip's PIC portfolio, positioned between the 8-bit PIC16/PIC18 line and the higher-end 32-bit PIC32MZ series, and typically used in embedded control, USB device, and graphics applications that exceed 8-bit capability but do not require DSP extensions.
Key features include a MIPS32 M4K 32-bit core with 5-stage pipeline, 80 MHz maximum operating frequency yielding 1.56 DMIPS/MHz performance, 64KB Flash with self-programming support, 16KB SRAM, a 10-bit 1 MSPS analog-to-digital converter with up to 16 channels, USB 2.0 full-speed device/host/OTG controller, two I2C, two SPI, and two UART modules, plus a Parallel Master Port for external memory or graphics interfaces.
The architecture uses a 5-stage pipeline with separate instruction and data Flash buses to deliver 1.56 DMIPS/MHz, enabling deterministic interrupt response for real-time control loops. The integrated USB 2.0 full-speed On-The-Go controller supports both device and host roles without an external PHY, while the Peripheral Pin Select (PPS) remapping allows flexible assignment of digital peripherals to physical I/O pins.
Typical applications include industrial control and HMI panels, USB peripherals such as barcode scanners and HID devices, embedded data acquisition systems, low-cost graphics terminals driving TFT LCDs, and consumer electronics requiring 32-bit performance with low BOM cost.
Designers should note that the '80V' suffix indicates the 80 MHz speed grade with V temperature range (-40C to +105C), and the 'T' suffix denotes Tape and Reel packaging. The MR suffix indicates the 64-pin VQFN package, while the parallel PIC32MX320F064H-80V/MR ships in tray packaging. The MR package requires careful thermal pad soldering and 0.5 mm pad pitch layout discipline.

Aplicações típicas
PIC32MX320F064HT-80V/MR é adequado para 6 aplicaçãos: USB Human Interface Device (HID) Peripherals, Industrial HMI and Operator Panels, Embedded Data Acquisition Systems, Low-Cost Graphics Terminals, Consumer Electronics Controllers, Educational and Hobby Development Boards.
USB Human Interface Device (HID) Peripherals
The PIC32MX320F064HT-80V/MR fits USB HID peripherals because of its integrated USB 2.0 Full-Speed OTG controller and 80 MHz MIPS32 M4K core delivering 1.56 DMIPS/MHz for responsive HID polling. The on-chip USB controller handles device, host, and OTG roles without an external PHY, reducing BOM cost by approximately $1-2 versus external USB interface ICs. Typical use cases include USB barcode scanners, programmable keypads, gaming controllers, and industrial input devices where 64 KB Flash accommodates USB stack plus application code, while 16 KB SRAM holds HID report buffers and protocol state machines.
Recomendado
Industrial HMI and Operator Panels
The PIC32MX320F064HT-80V/MR suits cost-sensitive HMI panels requiring a 32-bit core, integrated USB for touch controller data, and the Parallel Master Port for direct connection to character or small TFT LCDs. The 80 MHz core delivers sufficient throughput to drive 320x240 QVGA displays at 30 fps refresh rates while servicing button scans and serial communications. The 16-channel 10-bit ADC reads analog inputs from potentiometers, thermistors, and 4-20 mA loop sensors in industrial control applications where the -40C to +105C extended temperature range ensures reliable operation in factory environments.
Recomendado
Embedded Data Acquisition Systems
The PIC32MX320F064HT-80V/MR is well-suited to multi-channel data acquisition systems thanks to its 16-channel 10-bit 1 MSPS ADC, integrated DMA controller, and 80 MHz processing headroom for real-time averaging, FFT, and threshold detection. The DMA engine transfers ADC results to RAM without CPU intervention, allowing sustained 1 MSPS sampling across multiple channels. The 16 KB SRAM is sufficient for circular acquisition buffers at typical sampling rates, while 64 KB Flash accommodates firmware with calibration tables and protocol stacks for Modbus, CAN, or Ethernet connectivity through external transceivers.
Recomendado
Low-Cost Graphics Terminals
The PIC32MX320F064HT-80V/MR drives small TFT LCD panels via its Parallel Master Port (PMP), which supports 8-bit or 16-bit data widths and dedicated control signals for STN, TFT, and OLED displays. The 80 MHz core provides enough bandwidth for 320x240 QVGA displays at acceptable refresh rates when using the PMP DMA mode, while Peripheral Pin Select (PPS) allows flexible routing of display control signals. Designers benefit from the integrated USB for firmware updates and the 64 KB Flash which accommodates basic graphics libraries, fonts, and UI assets without external memory.
Recomendado
Consumer Electronics Controllers
The PIC32MX320F064HT-80V/MR fits consumer electronics controllers such as smart home hubs, audio peripherals, and appliance controls because of its USB connectivity, ADC for sensor inputs, and competitive pricing around $3.50-$6.80 depending on quantity. The integrated peripherals (2x I2C, 2x SPI, 2x UART) connect directly to sensors, EEPROMs, Bluetooth/WiFi modules, and display drivers without external logic. The 64 KB Flash supports small RTOS implementations or bare-metal firmware for appliance control, while the 9x9 mm VQFN keeps board footprint compact for space-constrained consumer products.
Recomendado
Educational and Hobby Development Boards
The PIC32MX320F064HT-80V/MR appears on Microchip's PIC32MX starter kits and third-party educational boards because of its mature toolchain (MPLAB X IDE, XC32 compiler, Harmony framework) and rich peripheral set. The 80 MHz performance teaches students 32-bit embedded concepts without overwhelming complexity, while 64 KB Flash accommodates full USB stacks and graphics demos used in coursework. Hobbyists benefit from the wide community documentation, free Microchip samples, and the ability to migrate to newer PIC32MX1XX/2XX/3XX/4XX/5XX/6XX/7XX families with retained code structure when scaling to more demanding projects.

Notas de projeto
The 64-pin VQFN package has a center exposed thermal pad (EP) that must be soldered to a ground copper pour for electrical performance and thermal dissipation. Microchip recommends a 0.5 mm pitch land pattern with at least 4 thermal vias (0.3 mm drill) connecting the EP to the inner ground plane. Without proper EP soldering, junction temperature may exceed safe limits during high CPU loads with USB active, reducing long-term reliability.
The PIC32MX320F064HT-80V/MR requires decoupling on every VDD/VSS pin pair. Place one 0.1 uF ceramic capacitor (X7R, 6.3V minimum) within 2 mm of each VDD pin (pins 5, 22, 26, 36, 41) and one 10 uF bulk capacitor near the device. The internal 1.8V voltage regulator on VDD is enabled by default via the ENVREG pin (pin 64); tie ENVREG to VDD for normal operation. The VUSB pin (pin 47) requires a 0.1 uF + 4.7 uF pair for stable USB transceiver operation.
Do not confuse 'V' temperature suffix (-40 C to +105 C) with 'I' suffix (-40 C to +85 C) when ordering - the 'V' variant is required for extended temperature environments but may have longer lead times during allocation. Also verify whether you need 'T' (Tape & Reel) or non-'T' (Tray) packaging before finalizing the BOM, as swapping mid-production is expensive. The PGED1/PGEC1 pair (pins 15/16) and PGED3/PGEC3 pair (pins 62/63) are dual-purpose programming/debug pins - route them with short, direct traces to the ICSP header to avoid debug failures.
Place the 12 MHz primary crystal or oscillator within 5 mm of the OSC1/OSC2 pins (pins 11/12) and surround it with a ground guard ring to minimize EMI. The USB D+/D- traces (pins 45/46) must be 90 ohm differential, length-matched to within 2 mm, and routed over a continuous ground plane to meet USB 2.0 Full-Speed signal integrity requirements. Keep the VUSB trace short (under 10 mm) to minimize noise coupling into the USB transceiver. The MCLR reset line (pin 61) needs a 10 kohm pull-up to VDD for reliable operation.
