PIC32MX575F512HT-80V/MR - 80MHz 512KB Flash 32-bit MCU | Microchip
MPN: PIC32MX575F512HT-80V/MR ✓ Hoạt độngPIC32MX575F512HT-80V/MR Tóm tắt
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals (ADC, timers, communication controllers). PIC32MX5xx parts sit in the upper-mid tier of Microchip's PIC32 portfolio, balancing deterministic interrupt performance with a USB-OTG + CAN connectivity combination. The PIC32MX5 family belongs to the broader taxonomy: microcontroller -> embedded processor -> semiconductor IC. Compared to 8-bit PIC16/PIC24 devices, PIC32MX5 offers up to 80 MHz operation, M4K core, and significantly larger memory.
Key differentiating features of this part include 512KB Flash (512K x 8), 64KB RAM, USB-OTG with integrated transceiver support, one CAN 2.0B module, four UART, three SPI, two I2C, a 16-channel 10-bit ADC, five 16-bit timers, and 53 selectable I/O pins. The MR suffix denotes a 64-lead VQFN package with exposed pad for thermal dissipation, while the HT suffix marks high-temperature operation at 80 MHz with tape-and-reel packaging.
Architecturally, the PIC32MX575F512H combines the MIPS32 M4K Harvard core with a 5-stage pipeline, prefetch cache, and tightly-coupled peripherals designed for real-time USB and CAN workloads. The 80 MHz operation delivers 1.56 DMIPS/MHz performance per the MIPS M4K benchmark. The 64KB RAM supports dual-port DMA to peripheral buffers, which keeps USB isochronous throughput high.
Typical applications include USB HID/CDC device controllers, CAN node interfaces for industrial automation, embedded HMI panels with USB touchscreens, and point-of-sale terminals. The combination of 512KB Flash, USB-OTG and CAN makes the part a strong fit for connected industrial devices that must bridge to a PC host while speaking CANopen or DeviceNet on the factory bus.
When designing with this MCU, route VDD/VSS pairs to the internal exposed thermal pad to improve thermal dissipation, place a 0.0222 ohm ferrite or ferrite bead on VDD for each pair, and use the JTAG ports (TMS/TCK/TDO/TDI) for production programming.

Ứng dụng tiêu biểu
PIC32MX575F512HT-80V/MR phù hợp cho 7 Áp dụngs: USB HID Device Controllers, CAN Node Industrial Interfaces, Embedded HMI Panels, Point-of-Sale Terminals, Industrial Sensor Hubs, USB-to-UART Bridge Modules, Medical Monitoring Devices.
USB HID Device Controllers
The PIC32MX575F512HT-80V/MR fits USB peripheral designs because its integrated USB-OTG full-speed controller eliminates external PHY circuitry, while 512KB Flash comfortably holds HID/CDC/MSC class drivers alongside application code. At 80 MHz, the M4K core handles USB polling plus HID report processing within the 1 ms USB frame budget. Place the D+/D- lines as a 90-ohm differential pair routed directly from the IC pins to the USB connector, with the VBUS sense pin fed through a 10k resistor divider for proper OTG voltage detection. Power consumption in active HID mode is approximately 35-45 mA at 3.3V.
Được đề xuất
CAN Node Industrial Interfaces
The PIC32MX575F512HT-80V/MR suits CANopen and DeviceNet node designs because its on-chip CAN 2.0B controller with acceptance filters runs concurrently with USB, freeing the application layer to handle higher-layer protocols. The 64KB RAM supports CANopen object dictionary tables plus dynamic PDO mapping, while the 80 MHz MIPS M4K core executes CAN state machines without jitter. Connect the CANTX/CANRX pins to an external ISO 11898 transceiver such as the MCP2551 or TLE7259-3 for robust industrial bus isolation. Industrial grade parts support operation to +85C ambient.
Được đề xuất
Embedded HMI Panels
The PIC32MX575F512HT-80V/MR fits compact HMI panels with USB touchscreens because its USB-OTG and 16-channel 10-bit ADC enable both touch digitizer sampling and USB-CDC command exchange from a single chip. The 53 selectable I/O pins drive TFT backlight, GPIO keys, and PWM-controlled LED indicators without external logic. At 80 MHz, the part updates 320x240 QVGA panels at 30+ fps with simple on-screen graphics. Use the 10-bit ADC for touch-panel Y-coord readings at 100 ksps, more than sufficient for resistive touch sampling rates.
Được đề xuất
Point-of-Sale Terminals
The PIC32MX575F512HT-80V/MR fits POS terminals because it integrates USB device, CAN (for vending peripherals), UART (for receipt printers), and SPI (for secure payment modules) on a single 32-bit MCU. The 512KB Flash holds full USB CDC/ECM stacks, while 64KB supports EMV transaction buffers. Hardware crypto acceleration is not present, so consider PIC32MZ for PCI-PTS certified payment designs. Operating temperature V grade supports thermally constrained POS enclosure designs.
Được đề xuất
Industrial Sensor Hubs
The PIC32MX575F512HT-80V/MR fits industrial sensor hub gateways because its combination of 16-channel 10-bit ADC, USB, CAN, and four UART ports aggregate multiple analog and digital sensor inputs into a unified USB or CAN bus output. At 80 MHz, the M4K core performs sensor linearization and digital filtering without CPU bottlenecks. Connect analog sensors to AN0-AN15, route UART-connected digital sensors to dedicated UART channels, and use CAN to forward processed values upstream. Operating temperature V grade supports factory floor environments.
Được đề xuất
USB-to-UART Bridge Modules
The PIC32MX575F512HT-80V/MR fits USB-to-UART bridge designs because its USB-OTG controller and four UART channels enable multi-port bridge implementations in a single chip. The 64KB RAM buffers high-throughput UART data before USB transfers, while 512KB Flash holds the full USB CDC ACM driver plus custom protocols. Bridge up to four serial ports at 1 Mbaud each, totalizing 4 Mbaud sustained throughput, all routed to a USB 2.0 full-speed host. Consider FTDI or Silicon Labs CP210x for simpler single-port bridge designs.
Được đề xuất
Medical Monitoring Devices
The PIC32MX575F512HT-80V/MR fits non-critical medical monitoring peripherals (USB patient data loggers, CAN-based bedside telemetry) because its USB-OTG device controller streams patient data to a host PC, while the 16-channel ADC samples multiple biosensor inputs. At 80 MHz, the M4K core performs basic digital filtering on ECG, SpO2, and temperature channels. Note that IEC 60601-1 certification is NOT supported by PIC32MX5; use IEC 60601-1 certified medical parts. Operating voltage 2.3V-3.6V supports standard Li-ion battery chemistries.

Bảo phân biệt quan trọng
- Same 64-VQFN footprint as PIC32MX564F128H-I/MR, but 4x Flash (vsPIC32MX564F128H-I/MR)
- Higher Flash density than PIC32MX575F256H-I/MR at same 80 MHz (vsPIC32MX575F256H-I/MR)
- V temperature grade for higher-temperature operation vs I grade alternative (vsPIC32MX575F512HT-I/MR)
Ghi chú thiết kế
The PIC32MX575F512HT-80V/MR operates from 2.3V to 3.6V, and a common 3.3V rail is recommended. Place a 10uF bulk capacitor plus a 0.1uF ceramic decoupling capacitor as close as possible to each VDD/VSS pin pair (typically pairs at pins 3, 29, 34, 57). The exposed thermal pad must be soldered to a ground plane to provide thermal dissipation and a low-impedance ground return.
Route the USB D+/D- signals as a 90-ohm differential pair from pins RF2/RF3 directly to the USB connector, keeping the pair length matched within 150 mil. Place the common-mode choke and ESD protection diode within 5 mm of the connector. JTAG signals TMS/TCK/TDO/TDI (RB0/RB1 alternate function) should be routed to a 0.1 inch debug connector pinout for production programming access.
Do not confuse the HT suffix (high-temperature tape-and-reel packaging) with the temperature grade itself (V vs I grade). When migrating to industrial designs, choose the I grade variant explicitly rather than relying on the HT suffix. Also, the 80 MHz clock requires the OSCCON register configured with the correct PLL multiplier and divisor; the default internal 8 MHz RC oscillator must be configured before peripheral operation to avoid timing failures on USB and CAN peripherals.
