PIC32MX564F128HT-V/PT Overview
A microcontroller (MCU) is a single-chip computer containing a processor core, program memory (Flash), working memory (SRAM), and programmable peripherals. The PIC32MX564 family specifically belongs to the MIPS-based 32-bit PIC32 hierarchy, which scales up from 8-bit PIC microcontrollers into a higher-performance 32-bit architecture while remaining code-compatible with MPLAB Harmony and XC32 toolchains. Within the broader taxonomy, it sits as: microcontroller -> 32-bit MCU -> MIPS32 M4K architecture -> PIC32MX5xx family -> Microchip PIC32 portfolio -> embedded semiconductor category.
Key features: 80 MHz max operating frequency with 80 MHz peripheral bus, 128 KB Flash (128K x 8) supporting live update, 32 KB SRAM, integrated USB 2.0 full-speed OTG with on-chip transceiver, four DMA channels for low-CPU-overhead transfers, 10-bit ADC with up to 16 channels and 1 Msps conversion rate, and up to five 16-bit timers/capture inputs. Communication interfaces include two I2C, two SPI, and four UART modules, providing flexible multi-protocol connectivity.
Technical depth: the M4K core executes most instructions in a single cycle and includes a hardware multiply/divide unit plus DSP extensions. The memory map separates Flash, RAM, peripheral, and configuration regions, with configuration bits set during programming. The 'H' suffix in the part number denotes USB-capable silicon; 'T' indicates Tape and Reel packaging; the '-V' variant operates over -40C to +105C (V-grade), and 'PT' is the 64-pin TQFP package designator.
Typical applications: USB peripherals and HID devices, industrial HMI panels, sensor aggregation nodes with DMA-driven sampling, low-cost CAN/USB bridges (companion USB host or CAN controller), and consumer audio/display controllers with USB firmware update. The wide peripheral set also makes it suitable for USB-bootloader-equipped industrial nodes that need field firmware updates over USB OTG.
Design consideration: at 80 MHz the CPU draws roughly 70 mA from VDD; add bulk decoupling (10 uF) close to the package and per-pin 100 nF ceramics. USB OTG requires 0.1 uF on Vbus and careful PCB layout matching the on-chip transceiver reference design.

Typical Applications
PIC32MX564F128HT-V/PT is suitable for 6 applications: USB HID Peripheral Devices, Industrial HMI and Control Panels, USB Firmware Update Bootloader Hosts, Sensor Aggregation Nodes, Consumer Audio Controllers with USB Update, USB CAN Bridge / Gateway.
USB HID Peripheral Devices
The PIC32MX564F128HT-V/PT's integrated USB 2.0 full-speed OTG controller makes it ideal for USB Human Interface Devices (HIDs) such as custom keyboards, mice, and industrial input panels. Its 80 MHz MIPS32 M4K core comfortably handles USB endpoint servicing alongside device-specific logic. The 32 KB SRAM provides headroom for HID report buffers and small protocol stacks, while the on-chip transceiver eliminates the need for an external USB PHY. Placed as the single MCU on the device with USB D+/D- routed to the connector per USB-IF guidelines, it eliminates the BOM cost of a separate USB interface IC. Compared to an external USB-to-UART bridge, this integrated solution removes one component and one failure mode.
Recommended
Industrial HMI and Control Panels
The PIC32MX564F128HT-V/PT's 80 MHz performance, 16-channel 10-bit ADC, four DMA channels, and extended -40C to +105C (V-grade) temperature rating make it ideal for industrial HMI and control panels. The four DMA channels offload continuous ADC scanning and UART/SPI traffic without CPU intervention, while the 10-bit ADC suffices for potentiometer/thermistor readout. The V-grade temperature rating suits cabinet-mounted industrial panels. Placed as the main controller with the ADC sampling analog inputs and DMA transferring to RAM, it leaves CPU cycles free for the HMI logic. Compared to a discrete ADC + small MCU architecture, the integrated solution reduces BOM and PCB area.
Recommended
USB Firmware Update Bootloader Hosts
The PIC32MX564F128HT-V/PT's USB OTG host capability and 128 KB Flash make it well-suited as a USB host that delivers firmware to downstream devices in industrial nodes. Its 80 MHz MIPS32 M4K core can drive a USB mass-storage stack and a microcontroller Flash loader protocol in parallel. The 128 KB Flash holds the USB stack, the loader, and the firmware image, while DMA offloads USB endpoint traffic. Placed as the upstream programmer in a production line or field service tool, it eliminates the need for a PC at update time. Compared to an SD-card based bootloader, USB is faster and more controlled.
Recommended
Sensor Aggregation Nodes
The PIC32MX564F128HT-V/PT's 4 DMA channels, 10-bit ADC with up to 16 channels, two I2C and two SPI ports make it ideal for sensor aggregation nodes that combine analog and digital sensors. Its 80 MHz MIPS32 M4K core handles protocol translation while DMA streams ADC samples and sensor data to memory. The 32 KB SRAM accommodates small sensor buffers without external memory. Placed between a sensor farm and an upstream gateway, it locally preprocesses data, reducing gateway load. Compared to a low-end MCU with bit-banged I2C, the hardware peripherals and DMA reduce CPU load and code complexity.
Recommended
Consumer Audio Controllers with USB Update
The PIC32MX564F128HT-V/PT's USB OTG, 80 MHz core, and I2S-friendly timers suit consumer audio controller applications where USB firmware update is required. Its 80 MHz MIPS32 M4K core generates sample clocks and bit-bangs I2S while the on-chip USB provides update channel. The four DMA channels stream audio samples without CPU overhead, and the 32 KB SRAM holds audio buffers. Placed between the USB connector and the audio CODEC, it handles playback, control, and field updates. Compared to an external USB + DSP architecture, the integrated MCU reduces BOM.
Recommended
USB CAN Bridge / Gateway
The PIC32MX564F128HT-V/PT's USB OTG device mode plus 2x UART and 2x SPI makes it ideal for a low-cost USB-to-CAN/serial gateway when paired with an external CAN controller. Its 80 MHz MIPS32 M4K core processes the USB CDC protocol and translates to CAN frames via SPI. The 128 KB Flash holds USB stack plus gateway logic, while the 32 KB SRAM provides buffering. Placed as the bridge between a host PC and a CAN network, it eliminates dedicated CAN dongles. Compared to a commercial USB-CAN dongle, this DIY solution is lower cost and customizable.

Key Differentiators
- Extended V-grade temperature range (-40C to +105C) (vs PIC32MX564F128HT-I/PT)
- Highest-density Flash in 64-TQFP at 128 KB (vs PIC32MX564F064HT-I/PT)
- Family member migration to 512 KB Flash without PCB rework (vs PIC32MX575F512HT-I/PT)
Design Notes
Power the PIC32MX564F128HT-V/PT from a 3.3V rail with at least 10uF bulk + 100 nF per VDD pin (pins 12, 28, 44, 64). For USB OTG operation, route VBUS (pin 36) to the USB connector's Vbus through an inline series ferrite bead, and add 0.1 uF + 10 uF decoupling on VUSB3V3 (pin 37). The on-chip USB transceiver requires a clean 3.3V supply; ripple above 50 mVpp can degrade USB signal integrity. Estimated: at 80 MHz the VDD current can reach 70 mA per the datasheet DC characteristics, so budget 100 mA of regulator headroom.
Route USB D+ and D- (pins 35, 34) as a 90-ohm differential pair with matched length (delta < 150 mil) to the USB connector. Place the common-mode choke and ESD protection array (e.g., USBLC6-2SC6) close to the connector side, not near the MCU. Keep the VUSB3V3 decoupling capacitor within 5 mm of pin 37. Place a ground pour on the layer beneath the D+/D- traces. Refer to Microchip AN5880 'USB PCB Layout Guidelines' for the reference design and AN1467 'USB CDC Virtual COM Port' for class firmware.
Do not exceed the 3.6V absolute maximum on any VDD pin; the USB VBUS pin (36) is 5V tolerant but requires the VUSB3V3 pin (37) powered for the transceiver to work. When migrating from PIC32MX564F128HT-I/PT (I-grade) to -V/PT (V-grade), confirm the rest of the BOM is rated -40C to +105C; substituting only the MCU without verifying passives/connectors is a common OEM pitfall. Estimated: the configuration bits must be set correctly to enable the USB PLL and the 80 MHz system clock - default config runs at 8 MHz RC.
