A PIC32MX5xx microcontroller is a 32-bit MIPS-based MCU in Microchip's PIC32 family, positioned between 8-bit PIC16/PIC18 and high-performance MIPS cores. It uses a Harvard architecture with 5-stage pipeline and hardware multiply/divide, enabling efficient C execution while retaining the PIC ecosystem of MPLAB X IDE, XC32 compiler, and Harmony framework. The part integrates dedicated USB and CAN peripherals, removing the need for external bridge chips in industrial and consumer designs.
Key features include 64 KB Flash (64K x 8) with pre-fetch buffer, 32 KB SRAM, 53 general-purpose I/O pins, four DMA channels for CPU-offload data movement, a Parallel Master Port (PMP) for external memory or graphics, and a 10-bit 1 Msps ADC with 16 channels. Communication peripherals include two I2C, two UART, and two SPI interfaces in addition to USB and CAN, giving designers broad protocol flexibility without external glue logic.
The 80 MHz core delivers 1.56 DMIPS/MHz (Dhrystone 2.1) and supports both MIPS32 and MIPS16e instruction mixes for code-density optimization. An 8 MHz internal Fast RC oscillator with PLL provides flexible clocking while reducing external component count, and the device supports industrial-grade -40C to +85C operation. Hardware trace and JTAG are supported via the standard MIPS Trace interface for real-time debug.
Typical applications include USB peripherals (HID, CDC, mass storage), CAN-based industrial nodes (sensor hubs, motor controllers), and embedded graphical user interfaces using PMP to drive character/graphic LCDs. The combination of USB host capability and CAN makes the part a strong fit for automotive infotainment sub-systems, point-of-sale terminals, and factory automation controllers.
When designing with this part, place the 100-pin TQFP on a 4-layer PCB with a continuous ground plane beneath the device and 0.1uF + 10uF decoupling on every VDD/VSS pair to manage switching noise from the USB and CAN PHYs. The integrated USB transceiver requires careful DP/DM trace impedance control (90 ohm differential) to pass USB compliance.

典型應用
PIC32MX564F064L-I/PF 適用於 7 應用s: USB Human Interface Device (HID), CAN-based Industrial Sensor Hub, USB Mass Storage / Data Logger, Embedded Graphical User Interface, Automotive Infotainment Sub-system, Point-of-Sale (POS) Terminal, IoT Edge Gateway / Bridge.
USB Human Interface Device (HID)
The PIC32MX564F064L-I/PF is a natural fit for USB HID peripherals - keyboards, mice, game controllers, custom input panels - because its integrated USB 2.0 Full-Speed Device/Host/OTG controller with on-chip transceiver eliminates external PHY/bridge chips. At 80 MHz the M4K core executes HID class drivers and the host-side report parser in <10% CPU load, leaving cycles for debouncing, RGB LED PWM, and capacitive touch sensing. The 4-channel DMA engine offloads endpoint IN/OUT transfers from the CPU, ensuring interrupt latency stays below 1 ms even under heavy traffic.
推薦
CAN-based Industrial Sensor Hub
In industrial sensor hubs and factory-floor I/O modules, the PIC32MX564F064L-I/PF's CAN 2.0B controller with hardware FIFOs and 16 filter/mask registers handles up to 1 Mbps bus traffic without CPU intervention. Its 16-channel 10-bit 1 Msps ADC reads thermocouple, pressure, and 4-20 mA sensors directly, while the 53 GPIO pins drive optocouplers, relay drivers, and status LEDs. Running the CANopen or DeviceNet stack at 80 MHz leaves ~50% CPU headroom for application-layer processing, and the 32 KB SRAM comfortably holds CAN message buffers.
推薦
USB Mass Storage / Data Logger
The PIC32MX564F064L-I/PF implements USB Mass Storage Class devices (USB drives, SD card readers, data loggers) by leveraging the integrated USB 2.0 FS Device controller and Parallel Master Port (PMP) to attach external NAND/SPI Flash. The 4 DMA channels move data between USB endpoints and PMP memory in the background, sustaining 800+ KB/s throughput at full-speed USB. Its 64 KB Flash comfortably stores the MSD bot/wrappers while 32 KB SRAM serves as the sector cache for write coalescing.
推薦
Embedded Graphical User Interface
For low-cost HMI panels driving character LCDs or small TFT displays, the PIC32MX564F064L-I/PF provides a Parallel Master Port (PMP) that directly interfaces to ST7565, KS0108, and similar controllers without external logic. At 80 MHz it redraws 128x64 monochrome frames in <5 ms, enabling smooth menus and progress bars. The 16-channel ADC supports touch-screen resistive overlays, while the 32 KB SRAM holds frame buffers and widget state.
推薦
Automotive Infotainment Sub-system
The PIC32MX564F064L-I/PF handles secondary automotive functions - HVAC control panels, steering wheel buttons, USB media ports - by combining CAN 2.0B for chassis communication and USB Host for thumb-drive media playback. Its 80 MHz MIPS core decodes MP3/WAV from USB mass storage while running CAN diagnostics on the second bus. The 53 GPIO directly drive segment LCDs, button matrices, and rotary encoder inputs without external mux chips.
推薦
Point-of-Sale (POS) Terminal
In POS terminals, the PIC32MX564F064L-I/PF drives the main keypad/scanner interface, USB-to-PC connection for transaction processing, and CAN/serial link to receipt printers or cash drawers. Its USB Device port appears as a CDC/ECM composite device to the host PC, while the on-chip UART controls the receipt printer and the GPIO pins drive the cash-drawer kick and beeper. The 64 KB Flash holds the firmware image and crypto keys; 32 KB SRAM buffers transaction packets before forwarding.
推薦
IoT Edge Gateway / Bridge
The PIC32MX564F064L-I/PF serves as an IoT bridge connecting legacy RS-485 industrial sensors to USB-attached host computers or CAN networks. The two UART ports handle Modbus RTU on RS-485, while the CAN port speaks CANopen to motor controllers, and USB Device appears as a virtual COM port to the host. Its 4 DMA channels relieve the CPU of byte-level buffer management, leaving MIPS for protocol translation, data aggregation, and timestamping for time-sensitive networks.

- Doubled Flash headroom (128 KB) available in same footprint (對比PIC32MX564F064L-I/PF vs PIC32MX564F128L-I/PT)

設計說明
Place a 0.1 uF ceramic decoupling capacitor within 3 mm of every VDD/AVDD/VSS pair, plus a single 10 uF bulk tantalum or ceramic near the device. Use a 4-layer PCB with a continuous ground plane directly under the 100-pin TQFP to minimize ground bounce. Estimated: at 80 MHz with USB active, peak current spikes reach ~120 mA, so the bulk cap must have <100 mOhm ESR at 1 MHz.
USB DP/DM traces must be routed as a 90 ohm differential pair with matched length within 150 mil, kept away from switching signals. Place the 27% series resistor on D+ close to the MCU pin per USB specification. The CAN TX/RX traces should likewise be kept short and routed away from clock lines to avoid crosstalk into the high-impedance CAN RX input.
Do not exceed the maximum VDD of 3.6 V - even brief transients above 4.0 V can permanently damage the USB transceiver. The VUSB pin requires a 10 uF capacitor; omitting it causes USB enumeration failures. When using the internal 8 MHz Fast RC oscillator with PLL, configure the PLL divider correctly before switching the SYSCLK source, otherwise the core will stall.
For low-power designs, leverage the PIC32MX564F064L-I/PF's sleep and idle modes: in Deep Sleep mode the core draws <20 uA with RTC running. Estimated: average current for a USB HID keyboard polling at 125 Hz is ~15 mA active and ~5 mA idle, so a 500 mAh Li-ion cell supports >24 hours of operation.
