PIC32MX575F512L-80I/PT Übersicht
A 32-bit microcontroller (MCU) is a single-chip computer based on a 32-bit datapath that can address more than 4 GB of memory, executes instructions out of Flash, and integrates peripherals such as timers, ADC/DAC, communication controllers, and GPIO. The PIC32MX family belongs to the broader category of microcontrollers -> embedded microprocessors -> semiconductors, and combines a Harvard architecture, 5-stage pipeline, and MIPS16e code compression to deliver high DMIPS/mm2 density for connected embedded designs.
Key features of this variant include dedicated DMA channels for USB, a parallel master port (PMP) for graphics or parallel memory, five 16-bit timers/counters, two I2C, two SPI, and a JTAG debugger (non-IP-C) interface. The 80 MHz core delivers 105 DMIPS throughput, while the 64 KB SRAM with 3 KB of auxiliary flash supports data logging and bootloader scenarios. The USB OTG peripheral supports Host, Device, and On-The-Go roles with an integrated PHY that eliminates external transceiver components, simplifying BOMs for connected products.
The architecture pairs a MIPS M4K RISC core with single-cycle multiply, divide, and bit-field instructions, a 5-stage pipeline, and a Harvard bus that allows simultaneous instruction fetch and data access. Up to 41 DMIPS can be sustained per MHz under MIPS16e compression, with 1.56 DMIPS/MHz typical. The 4-channel DMA controller offloads data movement between peripherals and RAM, freeing the CPU for application logic. The 2.3 V to 3.6 V operating range and on-chip brown-out reset plus watchdog timer improve robustness in industrial environments.
Typical applications include industrial automation, USB peripherals (HID/CDC/MSC and CDC+Ethernet bridging), CAN-bus nodes (automotive and industrial control), Ethernet-connected embedded web servers, point-of-sale terminals, and graphical HMI panels with resistive-touch sensing. The combination of USB OTG, CAN, and Ethernet in a single die is rare at this price point, simplifying BOMs in multi-bus gateways.
When designing with the PIC32MX575F512L-80I/PT, ensure that each VDD/AVDD pair has a 0.1 uF + 10 uF local decoupling network within 3 mm of the pin, and that the 8 MHz primary oscillator is paired with the required 1 ms startup delay. The USB pins D+/D- require a 90 ohm differential trace and 47 K pull-down on the ID pin for OTG operation; the CAN bus should include a TJA1050 or MCP2551 external transceiver since this die only exposes the protocol controller.

PIC32MX575F512L-80I/PT ist geeignet für 6 Anwendungs: Industrial Automation and CAN Nodes, USB Peripherals and CDC-Ethernet Bridge, Point-of-Sale Terminals, Graphical HMI Panels with Resistive Touch, Automotive Body and Comfort Modules, Connected Sensor Hubs and IoT Gateways.
Industrial Automation and CAN Nodes
The PIC32MX575F512L-80I/PT's CAN 2.0B controller with 1024 message buffers and 80 MHz core make it a strong fit for industrial CAN-bus nodes in factory automation. The industrial -40 C to +85 C temperature grade tolerates cabinet environments, while 105 DMIPS handles protocol conversion and supervisory logic in real time. The device is paired with an external MCP2551 CAN transceiver on the bus side; the integrated DMA channels offload CAN mailbox handling from the CPU, leaving headroom for sensor fusion and PID loops. The 100-pin TQFP footprint also exposes enough GPIO to drive opto-isolated inputs and relay outputs typical in PLC-style I/O modules.

USB Peripherals and CDC-Ethernet Bridge
The PIC32MX575F512L-80I/PT integrates a USB 2.0 On-The-Go controller with PHY plus a 10/100 Ethernet MAC, enabling a single-chip USB-to-Ethernet bridge or USB CDC device. The integrated PHY eliminates external transceiver components, simplifying BOMs in connected peripherals such as USB-Ethernet dongles, USB bar-code scanners, and USB Wi-Fi/Ethernet adapters. The 80 MHz core and 64 KB SRAM comfortably run Microchip's TCP/IP stack with HTTP server, while the parallel master port (PMP) can drive an LCD for HMI feedback. Engineers should follow the 90 ohm differential USB trace guidance and add a 47 K pull-down on the ID pin for OTG role detection.
Empfohlen
Point-of-Sale Terminals
The PIC32MX575F512L-80I/PT combines USB device, Ethernet, and enough GPIO to act as the central MCU in a point-of-sale (POS) terminal: USB for the mag-stripe/card reader, Ethernet for back-office connectivity, and the parallel master port to drive a graphical LCD or thermal printer. The 512 KB Flash fits the full Microchip USB stack plus application firmware, and 64 KB SRAM buffers transaction logs. The 80 MHz MIPS M4K core executes AES encryption for PCI-PTS style security at line speed, while the 16-channel 10-bit ADC reads keypad and battery monitor inputs. Drop-in compatibility with the PIC32MX575F512L-I/PT variant eases dual-temperature sourcing for indoor and outdoor POS kiosks.
Empfohlen
Graphical HMI Panels with Resistive Touch
The PIC32MX575F512L-80I/PT drives small graphical HMI panels through its parallel master port (PMP), which can interface directly to TFT displays up to QVGA resolution and read 4-wire resistive touch controllers via the on-chip ADC. The 80 MHz core and MIPS16e code compression keep the display refresh loop and touch polling inside budget, while 64 KB SRAM holds frame buffers for small panels. The 16-channel 10-bit ADC at 1 Msps captures touch coordinates with sub-millisecond latency. Compared with low-pin PIC32 parts, this 100-pin TQFP variant exposes enough GPIO for backlight PWM, status LEDs, and CAN/Ethernet uplink to a master controller.

Automotive Body and Comfort Modules
Although the PIC32MX575F512L-80I/PT is rated -40 C to +85 C (industrial, not AEC-Q100 automotive), it is widely used in non-safety automotive body and comfort modules such as seat controllers, mirror adjusters, and lighting modules where AEC-Q100 is not mandated. The CAN 2.0B controller talks to the vehicle bus, while the 16-channel ADC reads potentiometers and current shunts. The 80 MHz core handles LIN-to-CAN gateway logic and PWM generation for lighting dimming. For AEC-Q100 requirements, designers migrate to PIC32MK or dsPIC33 families, but for non-safety modules this part remains cost-effective.
Empfohlen
Connected Sensor Hubs and IoT Gateways
The PIC32MX575F512L-80I/PT's combination of USB OTG, Ethernet, CAN, and 16-channel ADC makes it a flexible hub MCU for IoT gateways aggregating sensor data over multiple buses. The 512 KB Flash supports full TCP/IP stacks plus application logic, while 64 KB SRAM buffers network packets before forwarding. The 4-channel DMA offloads I2C/SPI sensor reads, freeing the MIPS M4K core to run MQTT or HTTP clients. The 80 MHz core delivers 105 DMIPS, ample for edge preprocessing such as averaging, FFT, or thresholding before cloud upload. The 100-pin TQFP (PT) package is well supported by low-cost carrier boards.

Designhinweise
Decouple each VDD/AVDD pair with a 0.1 uF ceramic placed within 3 mm of the pin and a bulk 10 uF tantalum or ceramic on each power domain. The PIC32MX575F512L-80I/PT operates from 2.3 V to 3.6 V and integrates brown-out reset, but proper decoupling is critical to avoid spurious resets during USB or Ethernet events. Place the bulk capacitor where the USB VBUS sense and AVDD traces converge, since switching on those pins causes the largest transient currents.
Route the USB D+ and D- traces as a 90 ohm differential pair with continuous reference ground beneath, and place the 47 K pull-down on the USB ID pin close to the IC. Keep total USB trace length under 50 mm to meet USB 2.0 signal-integrity requirements. For the Ethernet MAC, route RMII signals length-matched to within 50 mils and isolate the PHY clock from noisy digital regions.
The PIC32MX575F512L-80I/PT die only exposes the CAN protocol controller; an external MCP2551 or TJA1050 transceiver is required on the bus. Common pitfalls include omitting the transceiver, mismatching the 120 ohm bus termination, and forgetting the CAN error-passive interrupt handling. Also note that the 8 MHz primary oscillator startup must include the datasheet-mandated 1 ms delay before code execution to avoid oscillator-failure lockups.
At 80 MHz and 3.3 V, the PIC32MX575F512L-80I/PT dissipates roughly 200-300 mW worst-case with all peripherals active, well within the 100-pin TQFP thermal envelope. The dominant thermal path is the exposed copper pad beneath the TQFP (PT) package; ensure continuous ground copper with thermal vias under the die-attach pad to keep junction temperature inside the -40 C to +85 C industrial range. No external heatsink is required for typical industrial-automation or HMI use cases.
Place the 8 MHz crystal and its load capacitors within 5 mm of the OSC1/OSC2 pins, and keep oscillator traces short and surrounded by ground pour. For ADC accuracy, route analog and digital grounds as a star-ground at the AGND pin, and add a small ferrite bead between AVDD and VDD if analog noise is observed. The parallel master port (PMP) traces should be length-matched for reliable TFT or external-memory operation.
Compliance-Informationen
RoHS compliant per Microchip product page. -80I/PT uses lead-free terminations suitable for Pb-free reflow per JEDEC J-STD-020. Not AEC-Q100 qualified (industrial -40 C to +85 C temperature grade only); for AEC-Q100 applications choose PIC32MK or dsPIC33 families.
