PIC32MX564F128H-V/MR Übersicht
A 32-bit microcontroller (MCU) is a single-chip processor integrating a CPU core, Flash program memory, SRAM data memory, and programmable peripherals. PIC32MX devices sit in Microchip's MIPS-based 32-bit MCU family, bridging 16-bit PIC24/dsPIC and the higher-end Cortex-M SAM families. They are positioned as low-cost, USB-capable 32-bit solutions for industrial and consumer embedded designs.
Key features include MIPS16e code compression for up to 40% smaller code density, a 5-stage pipeline with hardware multiply/divide, 16-channel 10-bit ADC, 4-wire resistive touch controller, and parallel master port for external memory or graphics. The integrated USB OTG controller supports Host, Device, and On-The-Go roles without an external PHY.
Architecturally, the PIC32MX5xx family is built on a 0.25um process with on-chip 1.5 kB instruction cache and prefetch buffer that boost Flash throughput at 80 MHz core clock. The 5-channel DMA controller offloads ADC, SPI, UART, and I2S transfers, freeing the CPU for application logic.
Typical applications include USB peripherals (HID, CDC, MSD), industrial control panels, home automation gateways, sensor hubs with logging, and low-cost graphical HMI. Its USB OTG capability is especially valuable when the device must toggle between host (reading a USB flash drive) and device (PC tether) roles.
When designing, ensure the 64-pin VQFN exposed pad is soldered to a sufficient copper area for thermal dissipation at full 80 MHz. Decouple each VDD/VUSB pair with 100 nF plus 4.7 uF bulk; route the 8 MHz primary oscillator traces short and guarded. Use Microchip's MPLAB X IDE plus Harmony or legacy MLA stacks for USB class drivers.

Typische Anwendungen
PIC32MX564F128H-V/MR ist geeignet für 6 Anwendungs: USB HID/CDC/MSD Peripheral Devices, Industrial Sensor Hubs and Data Loggers, Home Automation Gateways, Low-Cost Graphical HMI Touch Panels, Medical Point-of-Care Devices, USB Host Reading Flash Drives / Data Exporters.
USB HID/CDC/MSD Peripheral Devices
The PIC32MX564F128H-V/MR's integrated USB 2.0 Full-Speed OTG controller with internal 1.5 kohm pull-up on D+ makes it a single-chip solution for USB HID keyboards, CDC virtual COM ports, and MSD mass-storage devices. Designers benefit from 80 MHz CPU bandwidth (50 DMIPS) to handle USB protocol, descriptor parsing, and application logic concurrently. The 128 KB Flash accommodates full USB class stacks (HID + CDC composite) plus custom application code, while the 32 KB SRAM handles USB endpoint buffers plus working RAM. Compared to ARM Cortex-M0+ alternatives, the MIPS32 M4K delivers higher single-thread throughput at the same clock rate.
Empfohlen
Industrial Sensor Hubs and Data Loggers
The PIC32MX564F128H-V/MR's 16-channel 10-bit ADC with 1 Msps conversion rate and 5-channel DMA makes it ideal for multi-sensor data acquisition nodes. The V-grade -40C to +105C temperature rating supports deployment in factory floors, outdoor cabinets, and process-control panels. The 32 KB SRAM stores time-stamped sensor samples before USB OTG transfers them to a USB flash drive or upstream host. Six UART ports enable simultaneous connection to RS-485 Modbus sensors, GPS, and cellular modems, while the 80 MHz core runs real-time control loops at 1 kHz sample rate with margin to spare.
Empfohlen
Home Automation Gateways
With USB OTG host mode, the PIC32MX564F128H-V/MR can read files from a USB flash drive for firmware update or configuration import, while in device mode it presents a CDC/HID interface to a home automation controller. The 6 UART ports simultaneously interface to Zigbee, Z-Wave, RS-485 wired sensors, and Wi-Fi modules (e.g., via AT commands). Its 80 MHz MIPS core runs a small TCP/IP stack through a serial-to-ethernet bridge, while the 128 KB Flash holds a multi-protocol translator application.
Empfohlen
Low-Cost Graphical HMI Touch Panels
The PIC32MX564F128H-V/MR integrates a 4-wire resistive touch controller and parallel master port, enabling direct connection to small TFT LCDs (e.g., 320x240 QVGA) for graphical user interfaces. The 80 MHz core and 32 KB SRAM comfortably drive a simple emWin/uCGUI interface, while 128 KB Flash stores font tables, icons, and multilingual strings. The DMA controller offloads SPI/parallel display refresh, freeing CPU cycles for touch event processing. USB OTG supports field firmware updates via USB stick.
Empfohlen
Medical Point-of-Care Devices
The V-grade temperature rating, USB device mode (for tethered data transfer to a PC), and integrated 10-bit ADC suit the PIC32MX564F128H-V/MR for entry-level medical devices such as glucose meters, pulse oximeter front-ends, and portable spirometers. The 32 KB SRAM buffers patient measurement data, and 128 KB Flash stores calibration tables and GUI graphics. Microchip's IEC 60730 Class B functional safety library is available for this MCU family, simplifying compliance for household medical equipment. The exposed-pad VQFN-64 package provides stable thermal performance for continuous-sensing applications.
Empfohlen
USB Host Reading Flash Drives / Data Exporters
The PIC32MX564F128H-V/MR's USB OTG host mode lets embedded devices read files from FAT-formatted USB flash drives without a PC, enabling field data export from industrial, scientific, or remote-sensor installations. The 32 KB SRAM holds a small file-system cache, while the 80 MHz CPU runs Microchip's USB Host Mass Storage Class driver plus FATFS file-system middleware. Combined with the 5-channel DMA, sustained read throughput of several hundred KB/s is achievable. Designers can also support USB-to-UART bridge mode for diagnostics.

Wichtigste Unterscheidungsmerkmale
- USB OTG native integration without external PHY (vs. PIC32MX270F256D-I/SO)
- Higher CPU frequency than PIC32MX1/2 series (vs. PIC32MX270F512L-50I/PT)
- V-grade -40C to +105C temperature range (vs. PIC32MX564F128HT-I/MR)
Designhinweise
The VQFN-64 (9x9 mm) package has a small thermal pad that must be soldered to a continuous ground plane of at least 1 square inch for safe operation at 80 MHz. Estimated: at 80 MHz full CPU load, the device draws approximately 70 mA from 3.3 V (~230 mW). With a properly stitched exposed pad and 4-layer PCB, theta_JA drops below 30 C/W, keeping junction rise under 7C above ambient. Without proper EP soldering, junction temperature can rise 30-40C and degrade long-term reliability.
Place one 100 nF decoupling capacitor within 3 mm of each VDD/VSS pair (pins 14, 29, 42, 60), plus a single 4.7 uF bulk capacitor near the package. The 8 MHz primary oscillator traces (OSC1/OSC2) must be kept short, symmetric, and surrounded by a grounded guard ring to minimize EMI. USB D+/D- traces must be 90 ohm differential with length matching within 150 mil; route them on the top layer with continuous ground beneath. Add a ferrite bead on VUSB if the USB bus can be back-powered.
Do not leave the ICSP pins (PGECx/PGEDx) floating during operation - tie them to VDD or GND through 10 kohm resistors to avoid spurious debugger-entry resets. The 32 kHz secondary oscillator (SOSC) pins must be left NC or terminated properly when unused to prevent shoot-through. Always configure unused GPIO as outputs driving low to minimize power consumption. The NVM unlock sequence must be exactly per datasheet - deviation will lock the Flash controller.
Compliance-Informationen
RoHS and REACH compliant per Microchip product environmental documentation. VQFN package is Pb-free matte tin finish with halogen-free mold compound. Not AEC-Q100 qualified - automotive applications should use the PIC32MX family members with explicit Q100 qualification. JEDEC J-STD-020 reflow profile compatible to 260C peak.
