PIC32MX564F064HT-I/MR Overview
A microcontroller (MCU) is an integrated circuit that combines a processor core, program memory (Flash), working memory (RAM), and a rich set of on-chip peripherals on a single die. Within the broader taxonomy, the PIC32MX564F064H belongs to the MCU family -> 32-bit MCU -> MIPS-based MCU -> general-purpose embedded MCU hierarchy, and is part of the PIC32MX5xx performance segment from Microchip, which targets applications requiring USB, CAN, or DSP (audio) capability at moderate clock rates.
Key features include 53 general-purpose I/O pins, 4 DMA channels for low-CPU-overhead data movement, multiple serial interfaces (UART, SPI, I2C), a 10-bit ADC with up to 16 channels, and a Parallel Master Port (PMP) for external bus/display interfaces. The integrated USB 2.0 full-speed On-The-Go (OTG) controller and CAN 2.0B module eliminate the need for external connectivity ICs in many designs, reducing BOM cost and PCB area. Code protection and trace/debug support via 2-wire programming/debug (ICSP) round out the feature set.
The PIC32MX564F064H uses the proven MIPS M4K Harvard architecture with a 5-stage pipeline, single-cycle hardware multiply/divide, and prefetch/cache logic that boosts effective throughput from Flash. Operating from 2.3V to 3.6V with low-power run, idle and sleep modes, the device supports industrial temperature range (-40C to +85C) and is suitable for consumer, industrial, and automotive-after-market applications.
Typical applications include USB peripherals (HID, CDC, mass storage), CAN-based industrial control and motor drives, audio processing with the on-chip I2S/AC97/DSP peripheral, and Human-Machine Interface (HMI) panels with LCD/PSP via PMP. The combination of USB + CAN + reasonable Flash/RAM also makes it a popular choice for bridging gateways and protocol converters in industrial automation.
When designing with this part, verify that your code footprint fits within 64 KB Flash and 32 KB RAM after the USB stack, CAN driver and any RTOS overhead. The 64-VQFN (9x9) package requires careful thermal pad soldering - follow Microchip's soldering profile and use a 4-layer PCB with a grounded thermal pad for best thermal and EMI performance.

USB HID Peripheral Device
The PIC32MX564F064HT-I/MR's integrated USB 2.0 Full-Speed OTG controller and 4 DMA channels make it an excellent fit for USB HID peripherals such as keyboards, mice, game controllers, and custom input devices. The on-chip USB transceiver eliminates external PHY circuitry, while DMA offloads endpoint data movement from the CPU, freeing MIPS for HID report processing. With 64 KB Flash, the MCU comfortably hosts the Microchip USB stack plus a HID class driver and application code; 32 KB RAM supports multi-endpoint configurations and HID report buffering. Operating from 2.3V-3.6V, it can be powered directly from the USB VBUS rail. Compared to a discrete USB controller + MCU solution, this single-chip integration reduces BOM cost by 30-40% and shrinks PCB area by roughly half.
Recommended
CAN-based Industrial Control
Industrial CAN nodes such as motor controllers, sensor hubs, and PLC expansion modules benefit from the PIC32MX564F064HT-I/MR's integrated CAN 2.0B module, 80 MHz MIPS M4K core, and 32 KB SRAM. The CAN peripheral supports both standard (11-bit) and extended (29-bit) identifiers at bit rates up to 1 Mbps, suitable for CANopen, DeviceNet, and J1939 stacks. With 32 KB RAM, designers can host a full CANopen stack plus application logic without external memory; the DMA controller offloads CAN mailbox transfers, leaving CPU cycles available for control loops. The 64-VQFN package with exposed thermal pad handles industrial -40C to +85C operation reliably. The combination of USB + CAN also enables dual-protocol gateways that bridge industrial CAN networks to USB-host computers.

Combined with 64 KB Flash and 32 KB SRAM, designers can implement audio effects, voice prompts, or simple codec bridges without an external DSP. The 80 MHz MIPS core provides roughly 80 DMIPS - enough headroom for sample-rate conversion, EQ filtering, and USB audio streaming simultaneously. Industrial audio applications such as intercoms, public-address front-ends, and hands-free kits leverage this integration to reduce system cost. The on-chip 10-bit ADC supports analog audio input alongside digital codec paths, enabling mixed-signal designs in a single MCU.
Recommended

Bridging USB to CAN is a common need in industrial automation, automotive diagnostics, and laboratory equipment. The PIC32MX564F064HT-I/MR uniquely combines both peripherals on a single die, enabling a compact gateway with no external bridge IC. The 32 KB SRAM buffers CAN frames while the USB full-speed endpoint handles host commands; the 4 DMA channels ensure deterministic throughput without CPU stall. Designers can implement CDC-ACM + CANopen, or vendor-class USB + J1939, entirely from firmware. The 64-VQFN package keeps board footprint small enough to fit inline with cable assemblies. The 80 MHz MIPS M4K core delivers sufficient processing for protocol conversion, filtering, and timestamping at CAN bus rates up to 1 Mbps.
Recommended
Human-Machine Interface (HMI) Panels
HMI panels with graphical LCD or character displays benefit from the PIC32MX564F064HT-I/MR's Parallel Master Port (PMP), which directly drives character LCDs, OLEDs, and small TFTs without external bridge logic. The 53 GPIO pins accommodate key matrices, rotary encoders, LEDs, and backlight control. With 64 KB Flash, designers can implement multilingual menus, bitmap graphics, and USB configuration channels; 32 KB RAM handles display framebuffers and event queues. The integrated USB OTG enables firmware updates and configuration via USB mass storage or CDC. Industrial temperature rating and a robust 64-VQFN package suit factory-floor HMI installations where reliability and longevity matter.
Recommended
Portable Data Acquisition (DAQ) System
Portable battery-powered DAQ modules use the PIC32MX564F064HT-I/MR for its 10-bit ADC with up to 16 input channels, integrated USB for host data transfer, and low-power run/idle/sleep modes that extend battery life. The 80 MHz core delivers real-time sampling at rates up to 1 Msps aggregate, while DMA channels buffer ADC conversions without CPU intervention. With 64 KB Flash and 32 KB RAM, designers can implement on-board calibration tables, linearization, and statistical processing before USB transfer. The 2.3V-3.6V supply range supports single-cell Li-ion power rails. The 64-VQFN (9x9 mm) footprint fits inside compact sensor enclosures alongside analog front-end ICs.

Design Notes
Estimated: For reliable operation of the 64-VQFN (9x9 mm) PIC32MX564F064HT-I/MR, the central exposed thermal pad must be soldered to a grounded copper pour with at least 16 thermal vias (0.3 mm drill, 0.5 mm pitch). A 4-layer PCB with a continuous ground plane beneath the MCU is recommended. The exposed pad also serves as the primary thermal dissipation path; without it, the junction temperature can rise 15-20C higher under full-load conditions, potentially violating the 85C ambient rating. Place 0.1uF decoupling capacitors within 2 mm of each VDD/VSS pair, and add a 10uF bulk capacitor near the IC.
The PIC32MX564F064HT-I/MR operates from a single 2.3V-3.6V supply. Use a low-noise LDO such as the MCP1700 or MCP1755 to generate the 3.3V rail from a USB VBUS or industrial 24V bus. Place a 10uF tantalum or ceramic capacitor at the VDD pins and 0.1uF ceramic decoupling on each adjacent VDD/VSS pair. The MCU's internal POR and BOR circuits handle power-on reset, but ensure VDD rises monotonically from 0V to 3.3V within 50 ms for proper startup. Avoid high-impedance traces on VDD that could couple switching noise from USB or CAN into the analog reference.
Common pitfalls with the PIC32MX564F064HT-I/MR include: (1) exceeding the 3.6V absolute maximum on any I/O pin when interfacing 5V logic - use a level shifter or resistor divider; (2) forgetting to configure the oscillator mode in configuration bits, which can leave the device running on the internal 8 MHz RC instead of the expected crystal; (3) ignoring the 53 GPIO limit - some package pins are shared with JTAG and must be reassigned via config bits; (4) underestimating USB stack Flash footprint - the Microchip USB stack consumes roughly 12-16 KB of Flash and 2-4 KB of RAM, leaving 48-52 KB for application code. Always prototype with headroom for stack updates.
