PIC32MX564F128LT-I/PT 概述
A 32-bit microcontroller (MCU) is a microprocessor core combined with on-die Flash program memory, SRAM data memory and a peripheral set in a single integrated circuit. PIC32MX5xx parts sit in Microchip's PIC32 family, which targets the MIPS32 M4K architecture - bridging 8/16-bit PIC MCU scalability with 32-bit performance for USB, CAN, graphics and audio bridging applications. The hypernym hierarchy is: PIC32MX564 subfamily -> PIC32MX5xx family -> PIC32 series -> 32-bit MCU -> microcontroller -> integrated circuit -> semiconductor.
Key features include a 32-bit MIPS M4K core with 1.56 DMIPS/MHz, hardware multiply/divide, 128 KB Flash (128K x 8), 32 KB SRAM, 4-channel DMA, full-speed USB 2.0 device/host/OTG, CAN 2.0B active, two I2C, two SPI, two UART, a 16-bit Parallel Master Port (PMP) for graphics/parallel memory and a 10-bit 1 Msps ADC. The 100-pin TQFP exposes 53 digital I/O lines, supporting multiple 5V-tolerant pins, hardware PMP bus and ICSP debugging.
Technical depth: the M4K core executes most instructions in one clock, giving 80 MHz core operation ~80 MIPS sustained throughput, with single-cycle 32-bit multiply and hardware divide. The 4-channel DMA engine offloads peripheral-to-memory and memory-to-memory transfers, freeing the core for control code. The 16-bit PMP enables direct connection to graphical LCDs, parallel SRAM and FPGA slaves. The integrated USB PHY supports low-speed, full-speed and full-speed OTG modes without external transceivers in most configurations.
Typical applications include industrial USB-to-CAN bridges, automotive infotainment subsystems (CAN node controllers), HMI panels with TFT LCDs using the Parallel Master Port, USB device/host bridges (barcode scanners, data loggers), and CAN-based sensor nodes. Designers select this part for code density advantages (one instruction per word vs 8-bit PIC) plus deterministic interrupt latency.
Design considerations: the 100-pin TQFP requires a 4-layer PCB with thermal relief for the 80 MHz switching current; 0.1 uF ceramic decoupling is recommended within 5 mm of every VDD/VSS pair. For USB designs, route D+/D- as a 90 ohm differential pair and place the 48 MHz crystal within 5 mm of the OSC pins.

典型应用
PIC32MX564F128LT-I/PT 适用于 6 应用s: USB-to-CAN Industrial Bridge, HMI Panel with TFT LCD, USB Barcode Scanner / Data Logger, CAN-Based Sensor Node, USB Device Firmware Upgrade Hub, In-Vehicle CAN Infotainment Subnode.
USB-to-CAN Industrial Bridge
The PIC32MX564F128LT-I/PT's integrated USB 2.0 full-speed device controller and CAN 2.0B active peripheral make it ideal for USB-to-CAN bridging gateways used in industrial automation and diagnostic tools. With 80 MHz MIPS32 M4K core throughput and 4-channel DMA, the MCU sustains bidirectional USB-CAN traffic at 1 Mbit/s without CPU saturation. Place the part on a 4-layer PCB with 90 ohm D+/D- differential routing and an MCP2551 CAN transceiver on the bus side.
推荐
HMI Panel with TFT LCD
The 16-bit Parallel Master Port (PMP) on the PIC32MX564F128LT-I/PT directly drives graphical TFT LCDs up to 320x240 resolution without external display controllers, ideal for compact HMI panels. Combined with 128 KB Flash for GUI assets and 32 KB RAM for frame buffers, the part provides enough headroom for menu structures and small bitmaps. The 80 MHz core renders text and icon updates fast enough for fluid 30 Hz refresh with low interrupt latency.
推荐
USB Barcode Scanner / Data Logger
USB host mode on the PIC32MX564F128LT-I/PT enables direct connection to USB barcode scanners, RFID readers and USB mass storage for portable data loggers in warehouse and field-instrumentation applications. The 4-channel DMA offloads USB bulk transfer handling, freeing the 80 MHz M4K core for parsing scanned data and time-stamping events. The 128 KB Flash holds firmware plus a small FAT file-system library for SD-card mirroring.
推荐
CAN-Based Sensor Node
For distributed industrial sensor nodes, the PIC32MX564F128LT-I/PT combines CAN 2.0B with a 10-bit 1 Msps ADC for periodic analog sampling and broadcast over the bus. The 53 I/O pins handle multiple analog and digital sensors, while 4 DMA channels stream ADC conversions into RAM without CPU intervention. Designers use the part for predictive-maintenance nodes reporting vibration, temperature and current at 100 kbit/s CAN bus rates.
推荐
USB Device Firmware Upgrade Hub
In USB DFU application hubs and firmware-loading fixtures, the PIC32MX564F128LT-I/PT acts as a USB device that receives firmware images and re-flashes downstream targets via UART, SPI or I2C. The 128 KB Flash and 32 KB RAM are sufficient for USB stacks plus custom bootloader code. Engineers can implement vendor-specific USB classes with the on-chip full-speed transceiver, eliminating external PHY cost.
推荐
In-Vehicle CAN Infotainment Subnode
The PIC32MX564F128LT-I/PT's CAN 2.0B active peripheral and 80 MHz throughput support in-vehicle sub-node controllers for infotainment, HVAC and lighting subsystems communicating on the vehicle CAN bus. The 16-bit PMP can drive small auxiliary displays while the USB port handles media input or smartphone mirroring protocols. The 100-pin TQFP package exposes enough I/O for keypad scanning and LED matrix driving.

设计说明
USB D+ (pin 97) and D- (pin 98) must be routed as a 90-ohm differential pair on a 4-layer PCB with controlled impedance. Keep the trace length under 50 mm and avoid stubs. Place the 48 MHz crystal within 5 mm of OSC1 (pin 30) and OSC2 (pin 31) with a grounded guard ring to minimize EMI pickup that would degrade USB signal integrity and cause enumeration failures.
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of every VDD pin (5, 44, 60, 80, 99) and a 10 uF bulk tantalum or ceramic on the main 3.3V rail. Estimated: at 80 MHz the part draws ~70 mA active and ~25 mA idle; the bulk capacitor prevents supply droop during USB burst events. Use a low-ESR ceramic for the bulk cap to handle transient load steps from USB full-speed packets.
Do not confuse the PIC32MX564F128L-I/PT suffix L (Industrial temperature grade, -40C to +85C) with the package code PT (100-pin TQFP). The 'T' in the MPN is the tape-and-reel packaging suffix, not a separate variant. When migrating from PIC32MX564F064L to PIC32MX564F128L, verify firmware size - although both fit in the same MPLAB X IDE project, the linker scripts and Flash layout differ between 64 KB and 128 KB parts.
Estimated: at 80 MHz core clock and 3.3V supply the part dissipates approximately 250 mW. The 100-pin TQFP has theta_JA around 50 C/W on a 4-layer JEDEC test board, giving a 12.5 C junction rise above ambient at full load - well within the industrial -40C to +85C rating. For enclosed housings, ensure 100 sq cm of copper pour on the top layer connected to VSS for additional heat spreading.
