PIC32MX575F256LT-80V/PF Descripción general
A 32-bit microcontroller (MCU) is an integrated computing system on a single silicon die containing a high-performance processor core, program and data memory, and a rich set of on-chip peripherals. Within the broader taxonomy, PIC32MX devices belong to the microcontroller (MCU) class, which sits under microcontrollers -> embedded processors -> semiconductors. The PIC32MX5XX/6XX/7XX family leverages the MIPS32 M4K core licensed from Imagination/MIPS, providing single-cycle multiply and hardware multiply-accumulate for DSP-style workloads while remaining code-compatible with the Microchip MPLAB XC32 toolchain.
Key features include 256 KB Flash organized as 256K x 8, 64 KB SRAM, 80 MHz maximum core clock with 1.56 DMIPS/MHz performance, full-speed USB 2.0 OTG with on-chip transceiver, CAN 2.0B active controller, a 16-channel 10-bit ADC with 1 Msps conversion rate, five UART/SPI/I2C peripherals configurable through PPS (Peripheral Pin Select), an 8-channel DMA controller, and five 16-bit timers/capture/compare/PWM modules. The wide-pin TQFP-100 package enables flexible PCB routing and full peripheral pin-out.
The architecture combines a 5-stage pipeline MIPS core with hardware multiply/divide, a tightly-coupled prefetch module that issues Flash accesses 128 bits per cycle, and dedicated peripherals connected via a multi-layer bus matrix. This design yields deterministic interrupt latency and high throughput for USB and CAN stacks while keeping active power consumption in the tens of milliamps at 80 MHz.
Typical applications include industrial control and HMI panels, USB peripherals (CDC/HID/MSD), CAN-bus nodes in automotive and industrial automation, low-cost graphics and TFT display controllers, sensor aggregation hubs, and portable medical or instrumentation devices. The combination of native USB-OTG and CAN makes it particularly suited to networked embedded devices.
When designing with this part, carefully allocate the Peripheral Pin Select (PPS) mapping before committing the PCB layout, and place a 32.768 kHz secondary crystal if the USB module requires SOF synchronization or RTC accuracy. Adequate decoupling (100 nF + 4.7 µF bulk) close to each power pin is mandatory for reliable 80 MHz operation.

Aplicaciones típicas
PIC32MX575F256LT-80V/PF es adecuado para 6 aplicacións: Industrial USB HMI Panel Controller, CAN-Bus Industrial Sensor Node, USB Barcode Scanner / Data Logger, Portable Medical Monitoring Device, Automotive CAN Gateway / OBD-II Adapter, TFT Display Controller with Touch UI.
Industrial USB HMI Panel Controller
The PIC32MX575F256LT-80V/PF's integrated USB-OTG full-speed controller with on-chip transceiver and 80 MHz MIPS32 M4K core make it an ideal host or device controller for industrial HMI panels and touch interfaces. Its 256 KB Flash comfortably holds USB CDC/HID stacks plus a small LVGL or emWin graphics library, while 64 KB SRAM handles display buffers. The 83 GPIO drive segmented LCDs, keypads, and LED indicators without external I/O expanders. The -40 C to +105 C V temperature grade supports factory floor and outdoor enclosures. At 3.3 V typical supply, it pairs directly with capacitive touch controllers and TFT displays using SPI. Designers save PCB area and BOM cost compared to external PHY plus MCU solutions.
Recomendado
CAN-Bus Industrial Sensor Node
The integrated CAN 2.0B active controller on the PIC32MX575F256LT-80V/PF handles ISO 11898-1 compliant communication at up to 1 Mbps, making it well suited to industrial CANopen or DeviceNet sensor nodes. Combined with 80 MHz MIPS throughput for protocol stack processing and 64 KB SRAM for message buffering, the MCU aggregates multiple sensor inputs (analog via 10-bit ADC, digital via SPI/I2C) and broadcasts them on a CAN bus. The 5 UART/SPI/I2C peripherals route to most GPIO via PPS, simplifying PCB layout. An external MCP2551 CAN transceiver handles the differential bus signaling. The wide operating temperature range supports factory and process-control deployments.
Recomendado
USB Barcode Scanner / Data Logger
For USB-connected barcode scanners and portable data loggers, the PIC32MX575F256LT-80V/PF delivers full-speed USB-OTG device mode without an external PHY, allowing direct USB cable connection to PCs. The 256 KB Flash stores USB HID/MSD class stacks and user firmware, while 64 KB SRAM buffers scanner bursts. The 8-channel DMA offloads UART barcode reads and ADC battery monitoring from the CPU. With 5 timer/CCP modules, the MCU generates PWM motor control for laser aimers and audible feedback tones. Low-power sleep modes (down to microampere standby) extend battery life in handheld scanners.
Recomendado
Portable Medical Monitoring Device
Medical monitoring devices such as pulse oximeters and blood-pressure monitors benefit from the PIC32MX575F256LT-80V/PF's 10-bit 1 Msps ADC for sensor signal acquisition, USB-OTG for charging and data transfer to a host PC, and low-power Sleep/Idle modes for battery operation. The 256 KB Flash stores RTOS kernels (FreeRTOS port available), sensor calibration data, and BLE/Wi-Fi firmware for optional wireless modules. Hardware multiply/accumulate supports lightweight DSP for filtering photoplethysmography signals. The V temperature grade (-40 C to +105 C) supports ambulance and outdoor use, while 5V-tolerant GPIO simplifies interfacing with legacy medical sensors.
Recomendado
Automotive CAN Gateway / OBD-II Adapter
The PIC32MX575F256LT-80V/PF's on-chip CAN 2.0B active controller and full-speed USB-OTG form an ideal bridge for OBD-II diagnostic adapters and CAN gateways that translate vehicle bus data to USB for tablets or PCs. The 80 MHz MIPS32 core runs automotive CAN stacks (CANopen, J1939 light) alongside USB-CDC device firmware, while 64 KB SRAM buffers multi-frame ISO-TP messages. Designers can use the 5 UART peripherals for additional LIN bus or RS-232 connections. Although not AEC-Q100 qualified, the V temperature grade makes it usable in cabin and aftermarket automotive accessories. An external MCP2562 high-speed CAN transceiver handles bus isolation and ESD.
Recomendado
TFT Display Controller with Touch UI
Driving small TFT displays up to 3.5 inch at modest frame rates is well within the PIC32MX575F256LT-80V/PF's capability: 80 MHz core and 64 KB SRAM allow framebufferless rendering with partial updates, while 5 SPI peripherals connect to displays with built-in controllers (ILI9341, ST7789V). The 8-channel DMA moves pixel data without CPU intervention, freeing cycles for touch-event handling and USB stack processing. The 5 timer/CCP modules generate backlight PWM and audio feedback tones. The 100-pin TQFP exposes sufficient GPIO for parallel 8-bit interfaces when higher throughput is needed. Use PPS to map SPI signals to convenient PCB locations.

Notas de diseño
Provide dedicated 100 nF + 4.7 µF decoupling capacitors at every VDD/VSS pin pair, placed within 2 mm of the package pad. The PIC32MX575 core can step current rapidly when USB packet handling triggers DMA bursts, and poor decoupling leads to VDD droop that can corrupt Flash operations. Estimate: at 80 MHz with all peripherals active, peak core current can reach ~80 mA, requiring low-ESR ceramic bypass for transient suppression.
Route the USB D+ and D- differential pair with 90 ohm differential impedance and length matching within 2 mm. Place the VUSB pin decoupling capacitor (4.7 µF or larger) as close to the pin as possible - this capacitor supplies the internal USB transceiver voltage regulator. Keep USB traces away from switching signals like PWM outputs and crystal oscillator traces to avoid EMI degradation of USB signal integrity.
Do not forget that the MCLR pin requires a 10 kohm pull-up to VDD for normal operation; a floating MCLR can cause intermittent resets. Also, the OSC1/OSC2 crystal traces must be short and guarded with a ground ring to avoid crosstalk. When using PPS (Peripheral Pin Select), assign unique I/O numbers to each remappable function - duplicate assignments silently disable lower-priority peripherals without raising an error.
Estimated junction temperature at 80 MHz full operation in still air: with theta_JA of approximately 50 C/W for the TQFP-100 package and typical active power dissipation of 250 mW, the junction rises roughly 12.5 C above ambient. For designs in enclosed housings without airflow, derate CPU clock to 60 MHz if ambient exceeds 70 C. The V-grade (-40 C to +105 C) supports operation up to 105 C junction with conservative power dissipation.
