PIC32MX564F064H-I/PT Descripción general
An MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O. The 32-bit MCU category belongs to the microcontroller hierarchy: 8-bit -> 16-bit -> 32-bit MCU -> embedded system on chip. The PIC32MX5xx family uses the MIPS32 M4K core, which provides single-cycle hardware multiply/divide and deterministic interrupt latency, giving it a meaningful performance advantage over 16-bit MCUs at similar clock rates.
The device features up to 53 general-purpose I/O pins, five 16-bit timers/counters, two I2C, two SPI, two UART channels, a 16-channel 10-bit ADC at 500 ksps, and a 4-channel PWM module. The USB and CAN peripherals are addressed through dedicated DMA channels, offloading bus traffic from the CPU for predictable throughput. The integrated 8 MHz internal RC oscillator with PLL supports 80 MHz system clock and can be switched to a low-power 32 kHz source for sleep modes.
Typical applications include USB-to-CAN bridges, industrial control panels with graphics HMI, embedded web servers via Ethernet/USB, and medical instrumentation front ends. The wide 2.3V to 3.6V supply range makes it well suited to 3.3V-system designs with battery backup.
Designers should provide a 10uF plus 0.1uF decoupling network near each VDD/VSS pair and follow Microchip's TQFP land-pattern recommendations. For CAN bus applications, add a 120-ohm termination and TVS protection.

Aplicaciones típicas
PIC32MX564F064H-I/PT es adecuado para 6 aplicacións: USB-to-CAN Industrial Bridge, Graphical HMI Control Panel, Embedded Web Server / IoT Gateway, Medical Monitoring Device Front End, Automotive Telematics and Body Controller, Industrial Sensor Hub with USB Logging.
USB-to-CAN Industrial Bridge
The PIC32MX564F064H-I/PT is purpose-built for USB-to-CAN bridges used in industrial gateways because it integrates USB 2.0 Full-Speed device/host and CAN 2.0B on the same die with four dedicated DMA channels. The 80 MHz MIPS M4K core sustains 125 DMIPS, sufficient to handle USB HID plus CANopen or J1939 protocol stacks concurrently. Placed between a host PC and a CAN bus, the part isolates the bus while offloading data movement to DMA, freeing the CPU for protocol translation. Its 32 KB SRAM comfortably holds USB endpoint buffers plus CAN message queues, and the 2.3-3.6 V supply simplifies integration with 3.3 V industrial backplanes.
Recomendado
Graphical HMI Control Panel
The PIC32MX564F064H-I/PT is well suited to graphical HMI panels because its parallel master port can drive TFT displays up to QVGA while the on-chip DMA channels offload pixel streaming. The 64 KB Flash and 32 KB SRAM are enough for a small RTOS plus a graphics library plus touch and keypad drivers. With 53 GPIO the part supports a TFT data bus, SPI touch controller, I2C sensors, and UART debug port simultaneously. Designers use it for industrial control panels, building-automation keypads, and appliance interfaces where USB device/host enables firmware upgrade sticks.
Recomendado
Embedded Web Server / IoT Gateway
The PIC32MX564F064H-I/PT runs Microchip's MPLAB Harmony TCP/IP stack plus a small HTTP server to deliver a low-cost embedded web server. The 80 MHz M4K core is adequate for HTTP plus REST plus SNMP workloads, while the USB peripheral can serve as a host for Wi-Fi dongles when Ethernet MAC is absent on this variant. With 32 KB SRAM the part holds TCP sockets plus packet buffers for small device counts, and the 64-pin TQFP keeps the BOM compact. Industrial IoT gateways use this combination to expose sensor data and accept OTA firmware updates via USB mass storage.
Recomendado
Medical Monitoring Device Front End
The PIC32MX564F064H-I/PT is used in medical monitoring front ends such as portable pulse oximeters, digital stethoscopes, and bedside sensor hubs where USB device or CAN communication is required. The 10-bit 500 ksps ADC samples physiological signals with sufficient dynamic range for pulse and respiration waveforms, and the 5 timers trigger precise sampling windows. Designers benefit from the 2.3-3.6 V supply, which allows direct Li-ion battery operation with simple regulators. Note that medical designs should use the -I industrial grade carefully and follow IEC 60601 isolation guidelines; this part is non-AEC-Q100 so it is suited to non-life-support medical devices only.
Recomendado
Automotive Telematics and Body Controller
The PIC32MX564F064H-I/PT is not automotive qualified, but designers use it in non-safety body-comfort modules and aftermarket telematics boxes. The CAN 2.0B controller talks to vehicle buses while USB streams data to a host PC or USB drive for data logging. The 53 GPIO control relays, LEDs, and switches. Designers must pair it with external CAN transceivers and watchdog supervisors. For AEC-Q100 designs, the alternative PIC32MX564F064H-V/PT offers -40 C to +105 C grade and qualification; aftermarket devices using the -I variant stay below automotive safety-critical thresholds.
Recomendado
Industrial Sensor Hub with USB Logging
The PIC32MX564F064H-I/PT acts as a multi-sensor hub that aggregates analog and digital sensor data and logs it via USB mass storage. The 16-channel 10-bit ADC reads temperature, pressure, and strain gauges; the two I2C busses pull in digital sensors; SPI talks to high-speed front ends; and USB host streams logs to a USB stick. The 32 KB SRAM holds rolling buffers while the 80 MHz core compresses and timestamps events. Industrial automation cabinets use this topology to retrofit legacy sensors with USB-exportable data without replacing the field wiring.

Notas de diseño
Decouple each VDD/VSS pair with a 10 uF tantalum or ceramic bulk plus a 0.1 uF ceramic placed within 5 mm of the pin pair. The AVDD/AVSS pair additionally needs a ferrite bead or small inductor from VDD to filter analog noise; the on-chip ADC achieves its 10-bit resolution only with this supply conditioning. Power-on reset is internal but designers should hold MCLR low until VDD stabilizes above 2.5 V for a clean boot.
Use a 4-layer PCB with continuous ground plane beneath the 64-pin TQFP; route all high-speed signals (USB DP/DN, CAN TX/RX, and crystal traces) over an unbroken reference plane and length-match USB DP/DN within 150 mil. The 8 MHz crystal load capacitors should sit adjacent to OSC1/OSC2 with the ground return through the local VSS plane rather than through signal traces. A USB ESD array (such as USBLC6-2) on the connector side is recommended because the internal ESD cells are rated only to 2 kV HBM.
Do not configure USB on the -I/PT when the VDD rail drops below 3.0 V: the USB PHY violates USB-IF signalling levels. The configuration bits must be programmed for the correct oscillator mode (XT with 8 MHz external or FRC internal) or the part will fail to boot. JTAG/ICSP pin sharing with PMD requires disabling PMP on those pins or programming will lock the device; configure the appropriate PPS register before enabling ICSP. Finally, the brown-out reset must be enabled in configuration bits to avoid undefined behaviour during slow VDD ramp-up.
Estimated: at 80 MHz full-load CPU activity, the part draws approximately 70 mA from VDD (3.3 V), giving roughly 0.23 W of dissipation. The 64-pin TQFP has theta_JA around 50 C/W on a 4-layer PCB, so junction rise above ambient is approximately 11.5 C; at 25 C ambient the junction sits near 36 C, well below the 125 C limit. Industrial -40 to +85 C designs have ample thermal margin without an explicit heatsink.
