PIC32MX564F064LT-I/PT - 80MHz 64KB Flash MCU w/ USB & CAN | Microchip
MPN： PIC32MX564F064LT-I/PT ✓ 啟用中PIC32MX564F064LT-I/PT 概覽
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and configurable peripherals around a unified internal bus. The PIC32MX5 family specifically belongs to the MIPS32 M4K processor lineage, sits within the broader PIC32 family of 32-bit PIC microcontrollers, and is part of Microchip Technology's microcontroller portfolio. Compared with 8-bit/16-bit MCUs, 32-bit parts offer significantly higher MIPS per mW, larger linear address space, and richer peripheral integration for connected embedded systems.
Key features of the PIC32MX564F064LT-I/PT include USB 2.0 full-speed On-The-Go (OTG) with integrated transceiver, CAN 2.0B active, Parallel Master Port (PMP) for external bus memory or graphics, I2S audio interface, up to 53 general-purpose I/O, and CTMU for capacitive touch / mTouch sensing. Industrial-grade -40C to +85C operation and 3.3V single-supply operation simplify power-tree design. Code protection and secure memory partitions protect firmware IP.
The MIPS32 M4K core implements a 5-stage pipeline with single-cycle multiply and hardware divide, supported by a configurable prefetch cache and 4-channel DMA that offloads peripheral-to-memory transfers. Dedicated peripherals such as the USB OTG controller and CAN module include DMA hooks, allowing sustained USB throughput and CAN traffic without CPU intervention - critical for real-time and connected designs.
Typical applications include USB peripherals (HID, CDC, MSD, audio class), CAN-connected industrial nodes (sensor aggregation, motor control, building automation), embedded HMI with graphics, and general-purpose connected IoT endpoints. The integrated USB and CAN peripherals eliminate external bridge ICs, reducing BOM and board area.
When designing with this part, observe the 3.3V supply requirement, provide adequate decoupling (0.1 uF + bulk), and follow Microchip's recommended PCB layout for the TQFP-100 exposed-pad variant if used. For migration to a lower-power PIC32MX1/2/3/4/5 series, verify peripheral differences in MPLAB X IDE before porting.

典型應用
PIC32MX564F064LT-I/PT 適用於 6 應用s: USB Human Interface Device (HID), CAN-Based Industrial Sensor Node, Embedded Graphical HMI Controller, USB-to-CAN Bridge Gateway, Portable Data Logger with USB, Connected IoT Edge Node (USB/CAN).
USB Human Interface Device (HID)
The PIC32MX564F064LT-I/PT's integrated USB 2.0 Full-Speed OTG controller with on-chip transceiver is ideal for USB HID peripherals such as keyboards, mice, custom input controllers, and industrial keypads. At 80 MHz the M4K core services HID report generation without taxing USB bandwidth, while the 4-channel DMA offloads endpoint transfers, leaving CPU headroom for application logic. With 64 KB Flash it fits HID stacks plus custom firmware; with 53 I/O it can scan matrix keypads or drive LEDs directly. Pair it with the MCP2200 or USBLC6-2SC6 for isolated/compliant designs, and use the Microchip Harmony USB stack for production-ready class drivers.
推薦
CAN-Based Industrial Sensor Node
The PIC32MX564F064LT-I/PT integrates CAN 2.0B active with hardware acceptance filters and DMA hooks, making it well-suited for industrial sensor nodes on a CAN/CANopen or J1939 bus. The 80 MHz core runs the CAN stack and 10-bit ADC sampling without bottleneck; the 4-channel DMA moves ADC samples directly to memory, leaving the CPU free for filtering. With 53 I/O it can interface SPI/analog sensors (temperature, pressure, flow) and drive actuators. Industrial-grade -40C to +85C operation matches factory floor requirements. Add a TJA1050 or MCP2551 CAN transceiver, ISO 1050 for isolation, and 120-ohm termination as required by the bus topology.
推薦
Embedded Graphical HMI Controller
With its Parallel Master Port (PMP) capable of driving external TFT displays up to 8-bit parallel, and the I2S peripheral for audio feedback, the PIC32MX564F064LT-I/PT is well matched to entry-level embedded HMI panels. The 53 I/O pins provide spare capacity for capacitive touch sensing via the CTMU peripheral, eliminating a dedicated touch controller. The 80 MHz MIPS core comfortably runs lightweight graphics libraries (legato, MPLAB Harmony Graphics) for menus and gauges. Use a 3.3V TFT with integrated controller (e.g., HX8347-I based), and pair with the PIC32MX5 family graphics examples for fast HMI prototyping.
推薦
USB-to-CAN Bridge Gateway
A natural application for the PIC32MX564F064LT-I/PT is a USB-to-CAN bridge gateway: USB 2.0 FS OTG on one side, CAN 2.0B active on the other, with the M4K core handling protocol translation. Engineers use this topology for laptop-based vehicle diagnostics, factory-floor PC tools, and lab instrumentation. The 64 KB Flash fits the USB CDC + CAN stack with margin for vendor commands; 32 KB RAM is adequate for buffers. Reference firmware is available in the Microchip Harmony USB Device + CAN library, and pair with MCP2515 (external CAN) or use the on-chip CAN for simpler designs.

Portable Data Logger with USB
The PIC32MX564F064LT-I/PT's combination of 32 KB RAM, 10-bit 1 Msps ADC, USB 2.0 FS OTG, and 53 I/O fits portable USB data loggers. Sample sensors at up to 1 Msps into RAM (with DMA moving samples directly to memory), then dump the buffer over USB to a host PC. The 64 KB Flash holds the USB MSC class driver and logger application. Industrial temperature range enables outdoor/vehicle deployments. Add a Li-ion charger (MCP73831) and an SPI FRAM (FM25V02) for non-volatile storage; the 53 I/O can monitor multiple sensor channels.
推薦
Connected IoT Edge Node (USB/CAN)
For IoT edge nodes requiring both USB connectivity (configuration/update port) and CAN (backhaul to vehicle/industrial bus), the PIC32MX564F064LT-I/PT offers a single-chip solution. The 4-channel DMA lets the MCU handle concurrent USB traffic (e.g., MQTT-over-USB, OTA updates) while sampling CAN messages for local processing. The industrial -40C to +85C range supports harsh environments. With 64 KB Flash the device fits TLS-over-USB or a small MQTT client plus the CAN driver; consider PIC32MX470F512LT-I/PT (512 KB Flash) when running WolfSSL or richer TCP/IP stacks.

主要差異化特點
- Tape & Reel shipping format optimized for SMT assembly (對比PIC32MX564F064L-I/PT)
- Doubles program memory headroom at same footprint (對比PIC32MX564F128LT-I/PT)
- Highest Flash and 50% faster core in the same package (對比PIC32MX470F512LT-I/PT)
- Migration path with larger memory, no board change (對比PIC32MX460F512L-80I/PT)
設計說明
The PIC32MX564F064LT-I/PT operates from a single 3.3V supply (2.3V-3.6V core range, per the family datasheet). Place a 0.1 uF decoupling capacitor close to every VDD pin, plus a 4.7 uF bulk capacitor near the supply input. The MCU's core runs at 80 MHz; switching noise can couple into analog rails, so place an additional ferrite bead + 10 uF cap on AVDD if you are sampling the 10-bit ADC at >500 ksps.
Route the USB D+ and D- lines (RG2/RG3) as a 90-ohm differential pair with matched length, kept short and isolated from noisy digital traces. Place the 48 MHz USB reference clock source as close to the MCU as possible and route it over a continuous ground reference. For CAN bus signals, place the MCP2551/ISO1050 transceiver near the bus connector and route the CAN_H/CAN_L pair as a 120-ohm differential.
Program/debug pins PGEDx/PGECx (RA0/RA1, RB6/RB7) must be accessible for MPLAB ICD/PICkit; do not route high-speed signals on these pins without bypass. If using trace, route TRCLK/TRDAT (RA6/RA7) to a header. The Parallel Master Port (PMP) pins PMD0-PMD7 on RE0-RE7 should be length-matched if driving a TFT directly to avoid skew.
Estimated: total Flash endurance is approximately 1000 erase/write cycles per row before wear. Implement wear-leveling if you plan to update configuration frequently. Do not exceed 3.6V on any VDD pin or 5V on any digital I/O - the part is NOT 5V tolerant. When migrating firmware from PIC32MX3/4 to PIC32MX5/6/7, recheck peripheral library versions because PPS pin mappings differ between sub-families.
Estimated: at maximum 80 MHz core clock and full peripheral activity, the PIC32MX564F064LT-I/PT draws approximately 70-90 mA from 3.3V (~250-300 mW). The 100-pin TQFP theta_JA is approximately 39 C/W (with standard JEDEC 4-layer test board), giving a ~10-12 C temperature rise - well within the industrial range. For forced-air or enclosed housings, verify with a thermocouple measurement.
