PIC32MX575F256L-80V/BG Обзор
A 32-bit microcontroller (MCU) is an integrated circuit containing a CPU core, program memory, data memory, and multiple peripheral interfaces on a single die. Within the embedded hierarchy, an MCU sits below a microprocessor (MPU) in scope - the MCU integrates memory and peripherals, whereas an MPU requires external components. The PIC32MX family belongs to Microchip's MIPS-based 32-bit MCU portfolio, engineered as a high-performance upgrade path for designers using PIC24/dsPIC devices who need additional throughput and full-speed USB connectivity.
The PIC32MX575F256L-80V/BG executes most instructions in a single cycle due to its 5-stage pipeline Harvard architecture, achieving 1.56 DMIPS/MHz. On-chip memory includes 256 KB Flash with pre-fetch cache and 64 KB SRAM, providing sufficient headroom for protocol stacks such as USB, TCP/IP, and CAN. The integrated 10-bit ADC with up to 16 channels supports conversion rates up to 1 Msps, while the parallel master port enables connection to external graphics or memory devices without glue logic.
Typical applications include industrial automation controllers with USB diagnostics, automotive body and comfort modules requiring CAN connectivity, USB-enabled medical devices such as blood-pressure monitors, and embedded HMI designs that need both USB and CAN for system integration. Its wide operating temperature range and dual communication interfaces make it especially useful where fieldbus and PC-side enumeration must coexist on the same node.
When designing with this device, allocate at least one decoupling capacitor per power pin pair (0.1 uF X7R ceramic) within 3 mm of the supply balls. For USB-OTG designs, the 90-ohm differential pair must be routed as a matched-length, impedance-controlled pair with a continuous reference ground plane. The -80V speed grade specifies the 80 MHz industrial temperature range (-40C to +105C); the -80I variant offers the wider -40C to +125C grade for harsher environments.
This page consolidates distributor pricing, drop-in same-package alternatives from the PIC32MX5 family, application notes for USB and CAN, and PCB layout guidance not typically compiled in the manufacturer datasheet. Engineers can compare same-footprint parts side-by-side and select a variant that matches the required temperature grade without redesigning the PCB.

Типичное применение
PIC32MX575F256L-80V/BG подходит для 6 применениеs: Industrial USB-to-CAN Gateway, Automotive Body Control Module, USB-Connected Medical Data Logger, Embedded HMI with Graphics PMP Display, Smart Energy / Building Automation Node, Portable Test and Measurement Instrument.
Industrial USB-to-CAN Gateway
The PIC32MX575F256L-80V/BG is a strong fit for industrial USB-to-CAN gateways because it integrates USB-OTG and CAN 2.0B on the same 80 MHz MIPS32 M4K core, eliminating the need for an external bridge IC. At 1.56 DMIPS/MHz the chip sustains full-speed USB 12 Mbps traffic while servicing 1 Mbps CAN frames with deterministic interrupt response under 100 ns. Place the MCU between a USB upstream port (type-B or micro-B) and an isolated CAN transceiver such as the ADM3053 or ISO1050; the 121-TFBGA footprint enables a compact PCB roughly 35x35 mm. The -40C to +105C industrial grade supports factory-floor enclosures, and the on-chip 10-bit ADC with 1 Msps conversion provides local diagnostics for supply and board-temperature monitoring. Designers should route the USB differential pair with 90-ohm controlled impedance and the CAN pair with 120-ohm characteristic impedance to preserve signal integrity.

Automotive Body Control Module
The PIC32MX575F256L-80V/BG suits automotive body and comfort modules that aggregate window, mirror, and lighting switches via CAN 2.0B and expose service data through USB. Its 80 MHz MIPS core handles CAN message arbitration, debounce, and USB CDC enumeration concurrently without CPU saturation. The on-chip 10-bit ADC scans up to 16 analog switches or sensors at 1 Msps aggregate rate, while the 256 KB Flash accommodates OBD-II-compatible diagnostics and bootloader. For under-hood or cabin-mounted modules, choose the -80I/BG variant (AEC-Q100 considerations aside) for +125C operation. Pair the MCU with a high-side driver array such as the VNQ5E050 or BTS50055 for direct actuator control. Layout note: route CANH/CANL as a matched differential pair, place a common-mode choke near the connector, and isolate the USB shield ground from chassis ground using a 1 M ohm bleed resistor plus 4.7 nF capacitor.

USB-Connected Medical Data Logger
The PIC32MX575F256L-80V/BG powers USB-connected medical data loggers such as spirometers, blood-pressure monitors, and wearable health patches. USB-OTG enables direct PC enumeration without an external PHY, while the 80 MHz MIPS core sustains data streaming to a host at 12 Mbps full-speed. The 64 KB SRAM buffers multi-sample frames before USB upload, and the 256 KB Flash holds firmware plus a USB bootloader for field upgrades. The 10-bit ADC samples sensor analog signals at up to 1 Msps, ideal for pulse oximetry current measurement or pressure transducer scaling. The BGA-121 footprint supports miniaturized handheld enclosures. Medical designs should add a watchdog timer, brown-out reset, and self-test firmware patterns per IEC 62304. The -40C to +105C temperature grade covers home and clinical environments; sterilization-grade housing extends the operational envelope further.

Embedded HMI with Graphics PMP Display
The PIC32MX575F256L-80V/BG drives small HMI panels through its Parallel Master Port (PMP), supporting 8-bit or 16-bit data interfaces to TFT LCDs up to QVGA resolution. The 80 MHz MIPS32 M4K core refreshes a 320x240 pixel buffer at 30+ fps with software graphics primitives or Microchip's MPLAB Harmony graphics library. The integrated 256 KB Flash stores frame buffers and UI assets; 64 KB SRAM holds the active display page. Designers typically pair the MCU with a 3.5-inch TFT panel, an external SPI Flash for asset storage, and a resistive or capacitive touch controller such as the AR1021. The BGA-121 package is well-suited to the compact HMI mainboard. Add a watchdog, decoupling per power pin, and an EMI bead on the display backlight supply to pass common industrial EMC tests.

Smart Energy / Building Automation Node
The PIC32MX575F256L-80V/BG fits building-automation nodes that bridge BACnet, Modbus, or KNX-style fieldbus networks to USB for commissioning. Its CAN 2.0B peripheral is repurposed as a generic UART-style interface to a building fieldbus transceiver, while the USB-OTG port provides local laptop connectivity for service technicians. The 80 MHz core executes the fieldbus state machine plus a TCP/IP-to-USB bridge stack simultaneously. The on-chip 10-bit ADC reads temperature, humidity, and occupancy sensors, and the 64 KB SRAM buffers BACnet/IP packets before transmission. The industrial -40C to +105C grade handles mechanical-room cabinets. Layout must isolate the USB shield ground and include a self-resettable PTC fuse on VBUS to protect against installer miswiring.

Portable Test and Measurement Instrument
The PIC32MX575F256L-80V/BG powers portable bench instruments such as USB oscilloscope probes, logic analyzers, and protocol sniffers. Its USB-OTG enables direct streaming of sampled data to a host PC for display, while the on-chip 10-bit ADC at 1 Msps delivers sufficient bandwidth for audio and low-frequency analog probing. The 256 KB Flash stores calibration constants and a USB bootloader for field firmware updates, and the 64 KB SRAM buffers sample frames before bulk transfer. The compact 121-TFBGA footprint allows a small handheld form factor. Pair the MCU with an external 12-bit or 16-bit ADC such as the MCP3301 for higher-resolution measurement channels, and add an SPI-controlled gain stage (MCP6S28) for autoranging input scaling. The -40C to +105C grade supports lab, factory, and outdoor field service.

Заметки по проектированию
Estimated: the PIC32MX575F256L-80V/BG draws up to 70 mA active (Vdd = 3.3V) including USB and CAN peripheral clocks running. Place a 0.1 uF X7R ceramic decoupling capacitor within 3 mm of every Vdd/Vss pin pair and a bulk 10 uF tantalum or ceramic on the main 3.3V rail. For USB bus-powered designs, add a 4.7 uF bulk capacitor on VBUS as required by the USB 2.0 specification. Keep analog AVDD separated from digital VDD with a ferrite bead for best ADC noise performance.
The 121-TFBGA package at 0.8 mm ball pitch requires microvia or via-in-pad PCB technology for reliable reflow soldering. Fanout the inner-row balls to internal signal layers using small microvias (8 mil pad / 4 mil drill). Maintain a continuous reference ground plane under the USB DP/DM and CANH/CANL differential pairs with 90 ohm and 120 ohm controlled impedances respectively. Avoid routing signal traces across power-plane splits to prevent return-path discontinuities. The exposed die-attach paddle (if present) should be soldered to a ground pad to reduce thermal resistance.
Do not confuse the -80V speed/temperature grade (-40C to +105C) with the -80I grade (-40C to +125C) when ordering - both share the same 121-TFBGA package but have different thermal qualifications. Ensure the configuration bits are programmed to enable the internal voltage regulator (default on POR for most PIC32MX5XX/6XX/7XX parts). For USB-OTG, the 5V tolerance of the D+/D- pins requires correct VBUS sensing before host role activation, otherwise the MCU may source 5V into a 3.3V-only peripheral. Always provide an external 32.768 kHz crystal for accurate USB full-speed frame timing when USB is enabled.
