PIC32MX575F512L-80V/PT 概要
What is a PIC32MX5xx microcontroller? It is a family of high-performance 32-bit flash microcontrollers built on the MIPS M4K core with a 5-stage Harvard pipeline and MIPS16e code compression, sitting in Microchip's PIC32 hierarchy (PIC32MX5xx -> PIC32MX -> PIC microcontrollers -> 32-bit MCU -> embedded processor). The '57x' sub-family adds full-speed USB-OTG with on-chip PHY and a hardware CAN 2.0b controller, targeting connected industrial and embedded nodes.
Key features of the PIC32MX575F512L-80V/PT include the 80 MHz / 105 DMIPS core, 512 KB Flash (512K x 8), 64 KB SRAM, an integrated full-speed USB 2.0 OTG transceiver (PHY), a CAN 2.0b module with 1024 transmit/receive buffers, 4 dedicated DMA channels for USB OTG, a 10-bit 1 Msps ADC, and 85 I/O-capable pins on the 100-pin package. The MIPS16e instruction mode compresses code by up to 40%, effectively enlarging the usable Flash density.
Architecturally, the device pairs a 5-stage Harvard pipeline (32-bit MIPS M4K) with separate Flash and SRAM buses, allowing simultaneous instruction fetch and data access. Dedicated DMA channels offload USB-OTG data movement from the core, freeing CPU cycles for application logic and ensuring deterministic USB throughput under heavy bus traffic.
Typical applications include USB-enabled industrial controllers, CAN-connected automotive body and diagnostics modules, embedded data loggers, USB peripherals such as human-interface devices, and small graphics/HMI front-ends that benefit from the large Flash budget. Designers choose this part when they need both USB-OTG and CAN in a single 32-bit MCU without external PHY or transceiver ICs.
When designing with this part, ensure the USB DP/DM traces are 90-ohm differential-controlled-impedance and kept under 50 mm, and provide an external 12 MHz crystal plus the correct PLL configuration to derive the 80 MHz system clock. The CAN bus requires an external transceiver (e.g., MCP2551) because the on-chip CAN module is protocol-only.

主な用途
PIC32MX575F512L-80V/PT の用途: 6 件s: USB-OTG Industrial Controller, CAN-Connected Diagnostics Module, Embedded Data Logger, USB Human-Interface Device (HID), Small HMI / Graphics Front-End, Connected Sensor Hub with USB Upload.
USB-OTG Industrial Controller
The PIC32MX575F512L-80V/PT's integrated USB 2.0 Full-Speed OTG transceiver (with on-chip PHY) and 80 MHz MIPS M4K core make it a natural fit for industrial controllers that expose USB host or device ports. The 4 dedicated DMA channels for USB OTG offload packet handling from the CPU, sustaining deterministic throughput under heavy bus traffic. With 512 KB Flash and 64 KB SRAM, it has ample code/data budget for USB stacks plus application logic. Place 90-ohm differential-controlled-impedance routing on the DP/DM lines and add ESD protection on the USB connector.
おすすめ
CAN-Connected Diagnostics Module
The PIC32MX575F512L-80V/PT's on-chip CAN 2.0b controller with 1024 transmit/receive buffers suits automotive-style diagnostics and factory-floor CAN nodes. The 80 MHz core runs OBD-II parsing and CANopen stacks comfortably, while 64 KB SRAM buffers incoming frames. Pair the part with an external MCP2551 or similar CAN transceiver, since the silicon only implements the CAN protocol layer. The -40C to +105C industrial range (V suffix) tolerates under-hood and chassis-mounted enclosures.
おすすめ
Embedded Data Logger
The PIC32MX575F512L-80V/PT's 512 KB Flash and 64 KB SRAM give designers enough headroom to buffer data on-device before flushing to USB mass storage or CAN uplink. The 10-bit ADC samples at 1 Msps and is sufficient for low-bandwidth analog channels typical of process and environmental loggers. The MIPS16e instruction set compresses code by up to 40%, leaving more Flash for data retention. Use a 12 MHz crystal plus the on-chip PLL to generate the 80 MHz system clock.
おすすめ
USB Human-Interface Device (HID)
The PIC32MX575F512L-80V/PT is well-suited to USB HID-class peripherals such as custom keypads, control surfaces, and instrumentation front panels. The integrated USB-OTG PHY eliminates an external transceiver, reducing BOM cost and PCB area. The 80 MHz core handles HID report generation, debouncing, and LED driving with cycles to spare. The 100-pin TQFP exposes 85 I/O lines, plenty for matrix-scanned keypads and rotary encoders.
おすすめ
Small HMI / Graphics Front-End
The PIC32MX575F512L-80V/PT's 512 KB Flash budget and 80 MHz core can drive small parallel-TFT or character LCD panels through the external parallel master port available on the 100-pin TQFP. Combined with USB-OTG for touch-panel data and CAN for backhaul to a controller, the part serves as a compact HMI node. The 64 KB SRAM accommodates double-buffered frame data for low-resolution QVGA panels.
おすすめ
Connected Sensor Hub with USB Upload
The PIC32MX575F512L-80V/PT aggregates multiple sensor inputs via its 10-bit ADC and digital I/O, then exposes data over USB device or CAN. With 4 dedicated DMA channels plus the 80 MHz core, sample buffering and protocol framing can run in parallel. The 512 KB Flash supports firmware-over-USB bootloader use cases for field-upgradable sensor nodes.

設計ノート
Route the USB DP/DM pair as a 90-ohm differential-controlled-impedance trace, kept under 50 mm with no stubs or vias on the differential pair. Place the ESD protection array within 3 mm of the USB connector. Decouple each VDD pin with a 100 nF ceramic capacitor placed as close as possible to the package pin, and add a bulk 4.7 uF tantalum or ceramic near the device. Estimated: assume 4-layer FR4 with 0.2 mm dielectric to hit 90 ohm differential impedance.
The on-chip CAN module implements only the CAN 2.0b protocol layer; you must add an external CAN transceiver such as the MCP2551 (or a 3.3V-compatible equivalent like the TJA1050) between the C1TX/C1RX pins and the bus. Do NOT connect the C1TX/C1RX pins directly to a CAN bus - the part will be damaged. Similarly, the USB OTG D+/D- lines require the on-chip PHY but still need proper impedance matching and ESD protection.
Place the 12 MHz crystal (or resonator) within 5 mm of the OSC1/OSC2 pins and keep the trace lengths matched. Add a guard ground around the crystal traces to reduce EMI coupling. The analog inputs (ANx) should be routed away from digital switching traces; if using the 10-bit ADC for more than 8-bit accuracy, add a 10 nF bypass at AVDD and place the AVDD trace in a star topology with the digital VDD.
