PIC32MX320F064HT-80I/PT 개요
A 32-bit microcontroller (MCU) is a programmable processor that integrates CPU core, Flash program memory, SRAM, and peripherals on one silicon die; PIC32MX MCUs add 32-bit MIPS M4K RISC performance to Microchip's PIC architecture, sitting between 8-bit PIC16/PIC18 and the higher-end PIC32MZ families in the microcontroller hierarchy: 32-bit MCU -> embedded processor -> microcontroller -> semiconductor. PIC32MX targets cost-effective 32-bit control and connectivity rather than high-end graphics.
Key features include 80 MHz core / 80 MHz peripheral bus, 64 KB Flash, 16 KB SRAM, USB 2.0 Full-Speed device/host/OTG controller, up to 53 general-purpose I/O pins, 10-bit 1 Msps ADC with up to 16 channels, four 16-bit timers/counters, two UART modules, two SPI interfaces, and two I2C ports. Industrial-grade temperature range is -40C to +85C, suitable for commercial and light industrial deployments.
Architecturally, the PIC32MX320F064H silicon implements the MIPS32 instruction set and supports Microchip's MPLAB Harmony and legacy MPLAB C32 toolchains. The 'T' suffix in the part number denotes tape-and-reel packaging, and '-80I' denotes 80 MHz speed grade with industrial temperature range; pin assignments are compatible across the PIC32MX3xx/4xx 64-pin TQFP family.
Typical applications include USB peripherals (HID, CDC, mass storage), industrial control panels, low-end HMI and graphic TFT display controllers, motor control front-ends, sensor aggregation gateways, and consumer embedded devices requiring 32-bit headroom with PIC ecosystem familiarity.
When developing with the PIC32MX320F064HT-80I/PT, observe the 2.3 V to 3.6 V supply range and provide adequate decoupling near each VDD/VBAT pin. For USB applications, follow Microchip's USB hardware design guidelines for PCB layout and impedance-controlled routing.
This page synthesizes distributor pricing, pin-compatible drop-in alternatives across the PIC32MX family, and practical design notes not found in the standalone manufacturer datasheet, giving engineers a one-stop decision reference.

일반적인 애플리케이션
PIC32MX320F064HT-80I/PT 적합 용도: 6 애플리케이션s: USB Human Interface Device (HID) Peripherals, Industrial Control Panels, Low-End HMI with Graphic TFT Display, Sensor Aggregation Gateway, Consumer Embedded Products with PIC Ecosystem, Motor Control Front-End.
USB Human Interface Device (HID) Peripherals
The PIC32MX320F064HT-80I/PT is well suited to USB HID peripherals such as keyboards, mice, custom input devices, and HID-class game controllers. The integrated USB 2.0 Full-Speed Device/Host/OTG controller eliminates external PHY cost, and 80 MHz MIPS M4K performance delivers sufficient headroom for HID report parsing and debounce logic. The 64 KB Flash fits Microchip's USB stack, and 16 KB SRAM handles HID report buffers plus descriptor storage. Place the part in a 64-pin TQFP with proper VBUS sensing on a dedicated pin, route USB D+/D- as a 90 ohm differential pair on the PCB, and follow Microchip's USB hardware design guidelines.

Motor Control Front-End
The PIC32MX320F064HT-80I/PT functions as a motor-control front-end for small BLDC, stepper, and brushed DC motors in appliances, fans, and small industrial pumps. The 80 MHz MIPS M4K core executes field-oriented control (FOC) and trapezoidal commutation algorithms, and the 10-bit ADC with 1 Msps sampling captures back-EMF and current-sense signals. The 5 16-bit timers produce PWM outputs for 3-phase motor bridges, and the 53 GPIO handles Hall sensors, fault inputs, and gate-driver controls. The 64 KB Flash fits standard FOC libraries, and 16 KB SRAM buffers state variables. Place the part away from switching power sections with proper isolation, and follow Microchip's motor-control PCB guidelines for analog/digital ground separation.

설계 노트
Estimated: The PIC32MX320F064HT-80I/PT operates from 2.3 V to 3.6 V with multiple VDD/VSS pins (pins 2, 13, 33, 45, 50, 53). Place a 100 nF decoupling capacitor as close as possible to each VDD/VSS pin. Add a bulk 10 uF tantalum or ceramic capacitor near the package to handle transient load steps during USB enumeration and peripheral switching. Tie unused VDD pins to the supply and unused VSS pins to ground. Avoid long PCB traces between VDD pins and capacitors to minimize parasitic inductance.
For USB 2.0 Full-Speed signalling, route USB D+ and D- as a 90 ohm differential pair on the top or bottom layer over a continuous ground plane. Keep the pair as short as practical (typically under 50 mm). Place the 15 kohm pull-down on D- and the 1.5 kohm pull-up on D+ (or controlled by software on the D+ pull-up enable pin). Provide proper VBUS sensing through a dedicated pin with voltage divider or dedicated USB VBUS sense pin. Follow Microchip's USB hardware design guidelines for full compliance.
Do not exceed 3.6 V on any VDD pin; the MCU is not 5V tolerant on digital I/O unless explicitly stated. Ensure the supply rise time meets Microchip's power-on reset (POR) specification. The 'H' suffix on the part number indicates the 64-pin TQFP package with USB; do not select the 64-pin QFN variant (different footprint). When migrating firmware between -40 and -80 speed grades, verify timing loops because peripheral and CPU clocks differ by 2x.
The 64-pin TQFP package has 0.4 mm lead pitch and 0.6 mm lead width - use 0.2 mm PCB trace width with 0.15 mm spacing for fanout. Place the IC on the top side with all peripheral connectors on the same edge for assembly-test access. Use 4-layer PCB stackup (signal-GND-power-signal) for best EMI/EMC performance in motor control or USB applications. Follow IPC-2221 design rules and Microchip's recommended PCB footprint in the package documentation.
