PIC32MX575F512LT-80I/BG Overview
A microcontroller is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and a rich set of peripherals (UART, SPI, I2C, USB, CAN, timers, ADC) onto one die. The PIC32MX5/6/7 family sits in the 32-bit MCU category above 8-bit/16-bit MCUs and below Cortex-M-class application processors, targeting connected embedded designs that need strong peripheral integration. Within that family, the 575 sub-family adds USB 2.0 Full-Speed OTG, a CAN 2.0B controller, and an Ethernet MAC on top of the baseline PIC32MX5 peripheral set.
Key features include 80 MHz core clock with 1.56 DMIPS/MHz (M4K core), 512 KB Flash, 64 KB SRAM, USB 2.0 Full-Speed OTG, one CAN 2.0B controller, 10/100 Ethernet MAC, five 16-bit timers/capture/compare, a 10-bit 1 Msps ADC with up to 16 channels, four UART, three SPI, and two I2C ports, plus a Parallel Master Port for external bus peripherals. Industrial temperature range -40C to +85C and 2.5V/3.3V operation make it suitable for connected industrial nodes.
The M4K core uses a 5-stage pipeline with Harvard architecture and a hardware multiply/divide unit. The 121-ball TFBGA package uses a 0.8 mm pitch that requires NSMD or SMD pads, controlled-impedance Ethernet traces, and bulk ceramic + tantalum decoupling on VDD/VUSB/VPLL rails. Compared with bare-metal Cortex-M0/M0+ parts at similar price points, the PIC32MX575F512L adds integrated USB, CAN and Ethernet in a single die, reducing BOM cost for connected-node designs.
Typical applications include USB peripherals, CAN-connected industrial controllers, Ethernet-enabled embedded web servers, audio consumer devices, and full-color HMI/graphical embedded applications. It is a strong fit for designs that must combine USB device/host connectivity with CAN-based fieldbus or 10/100 Ethernet on a single chip.
When designing with this MCU, allocate enough PCB real estate for the 0.8 mm pitch BGA fanout (microvia recommended). The PLL requires a clean low-jitter 8 MHz fundamental crystal with load capacitors matched to the crystal CL, and a ferrite bead on VDDCORE is required for stable operation across the industrial -40C to +85C range. A 10 uF bulk plus 0.1 uF per-pin decoupling pattern is recommended.

Typical Applications
PIC32MX575F512LT-80I/BG is suitable for 6 applications: USB Audio Class Device, CAN-Connected Industrial Controller, Embedded Ethernet Web Server, Graphical HMI Touch Controller, Portable Medical Sensor Hub, Smart Energy Meter with USB Logging.
USB Audio Class Device
The PIC32MX575F512LT-80I/BG's USB 2.0 Full-Speed OTG controller and 80 MHz M4K core are well-suited to USB Audio Class 1.0 streaming at 44.1/48 kHz stereo. The 512 KB Flash comfortably fits USB stack plus audio processing routines, while 64 KB SRAM handles USB endpoint buffers plus audio frame buffers. Compared to Cortex-M0+ parts at the same price, the PIC32MX575F512LT-80I/BG adds integrated USB PHY and avoids external crystal for USB clocking. Place the device near the USB connector with 90-ohm differential impedance on D+/D- and ESD protection rated for 8 kV contact discharge.
Recommended
CAN-Connected Industrial Controller
The PIC32MX575F512LT-80I/BG integrates one CAN 2.0B controller alongside USB and 80 MHz compute, making it a strong fit for industrial sensor/actuator nodes that bridge CAN fieldbus to a USB host. The 64 KB SRAM holds CAN TX/RX mailboxes plus protocol stacks such as CANopen or SAE J1939, while 512 KB Flash accommodates the application firmware. Industrial -40C to +85C operation supports factory-floor deployment. Add an external CAN transceiver such as MCP2551 or TJA1050, and use a common-mode choke on CANH/CANL for EMC compliance.
Recommended
Embedded Ethernet Web Server
The PIC32MX575F512LT-80I/BG combines USB OTG, CAN, 80 MHz M4K compute and a 10/100 Ethernet MAC into one die - a rare combination for low-cost connected nodes. The integrated MAC requires only an external RMII PHY (such as KSZ8041) to deliver full TCP/IP performance. 64 KB SRAM is enough for a lightweight HTTP/MQTT server with small payload handling, while 512 KB Flash fits a uIP/lwIP-based stack plus TLS helper. Industrial temperature and 2.5V/3.3V operation support 24/7 deployment in machinery and energy-use installations.
Recommended
Graphical HMI Touch Controller
The PIC32MX575F512LT-80I/BG runs the M4K core at 80 MHz with 1.56 DMIPS/MHz and integrates a Parallel Master Port (PMP) that drives TFT LCDs directly - a key advantage for graphical HMI front panels. The 512 KB Flash holds graphics libraries, fonts and UI assets, while 64 KB SRAM holds double-buffered framebuffer chunks. Compared to Cortex-M0+ parts that require an external display controller, the PIC32MX575F512L eliminates that component. Add a touch controller over I2C and route PMP data/control lines with impedance-controlled traces to the LCD connector.
Recommended
Portable Medical Sensor Hub
The PIC32MX575F512LT-80I/BG's low-power modes, 16-channel 10-bit 1 Msps ADC and USB OTG make it suitable as a portable medical sensor hub connecting multiple analog front-ends to a USB host PC. The 64 KB SRAM holds multi-channel sample buffers, while 512 KB Flash accommodates signal-processing routines. Industrial -40C to +85C operation supports clinical and home-health environments. Use a precision reference for the ADC, add ESD protection on USB lines, and route analog inputs as differential pairs with guard traces for noise immunity.
Recommended
Smart Energy Meter with USB Logging
The PIC32MX575F512LT-80I/BG combines 16 ADC channels, USB OTG and a 80 MHz core - a strong match for smart energy metering that measures multiple current/voltage channels and exposes data to a host for logging. The 512 KB Flash fits metering algorithms plus USB device stack, and 64 KB SRAM holds rolling-window sample data. Industrial temperature supports metering enclosures. Compared to bare Cortex-M0+ parts, the PIC32MX575F512L integrates USB and CAN on one die, reducing BOM. Add isolation barriers on ADC inputs per IEC 61010 and route current-sense paths away from digital lines.

Key Differentiators
- Integrates USB OTG + CAN 2.0B + 10/100 Ethernet MAC in one die (vs PIC32MX360F512L-80I/BG)
- Larger Flash and SRAM than PIC32MX564F128L-V/BG (vs PIC32MX564F128L-V/BG)
- Higher temp grade than standard commercial parts (vs PIC32MX575F512L-80I/PT)
Design Notes
The 121-ball TFBGA at 0.8 mm pitch requires NSMD pads with a 0.40 mm pad diameter and 0.55 mm solder mask opening. Use laser-drilled microvias (0.10/0.20 mm) on the inner escape layer; dog-bone fanout is also feasible for prototypes. The microvoid-free BGA reflow profile: preheat 150-200C for 60-90 s, soak at 200C peak for 60 s, ramp 2-3 C/s to 245C peak with 45 s TAL above 220C. Estimated: based on JEDEC J-STD-020 MSL-3 profile for 0.8 mm pitch TFBGA packages.
Place a 10 uF X5R bulk + 0.1 uF decoupling on each VDD/VUSB/VPLL ball pair. Add a ferrite bead (600 ohm at 100 MHz, 0402 size) on the VDDCORE rail. The internal voltage regulator requires a 4.7 uF low-ESR ceramic on the VDDCORE output. Ensure VUSB ball has its own 10 uF + 0.1 uF pair even if USB is disabled - leaving it floating can cause PLL jitter. Estimated: bulk capacitor sizing for 80 MHz core + USB traffic per Microchip family datasheet power-section guidance.
Do not omit the 8 MHz fundamental crystal with capacitors matched to crystal CL (typically 12-22 pF). The PLL multiplies this up to 80 MHz core; any jitter on the 8 MHz reference couples to the USB clock domain and can fail USB compliance. Crystal traces must be short (<5 mm) with a ground guard ring. Common pitfall: routing USB D+/D- lines without 90-ohm differential impedance - keep them length-matched to within 2 mm and avoid splits in the reference plane.
Route RMII Ethernet signals to the external PHY as a 50-ohm single-ended group, with length-matched clock and data lines to within 2 mm. Place a 22 ohm source-termination resistor in series with each RMII signal if the PHY is more than 25 mm away. Use a common-mode choke on the MDI+/- differential pairs. Keep the analog AVSS ball directly tied to a clean ground pour, separate from digital switching currents.
