PIC32MX575F256H-80I/PT - 80MHz 32-bit MCU 256KB Flash | Microchip
MPN: PIC32MX575F256H-80I/PT ✓ فعالPIC32MX575F256H-80I/PT نمای کلی
A PIC32 microcontroller belongs to the 32-bit MCU (microcontroller unit) family, which sits in the embedded processing hierarchy above 8-bit and 16-bit microcontrollers. Within Microchip's portfolio, PIC32MX devices target general-purpose 32-bit applications using the MIPS32 instruction set, sitting above PIC16 and PIC24/dsPIC families and below the higher-performance PIC32MZ family. The 32-bit core enables more complex software stacks, larger memory addressing, and richer peripheral integration than legacy 8/16-bit MCUs, while keeping deterministic real-time behavior.
Key features include 256 KB Flash, 64 KB SRAM, USB 2.0 full-speed OTG, CAN 2.0b, up to eight 16-bit timers, a 10-bit 1 Msps ADC with up to 16 channels, I2S for audio, and a PMP parallel master port for graphics. The 64-pin TQFP 10x10 mm package offers manageable PCB area with 0.5 mm pitch for hand-prototyping or low-density layouts, and the -80I industrial temperature grade supports -40C to +85C operation.
The M4K core uses a 5-stage pipeline with single-cycle multiply, hardware divide, and a configurable prefetch/cache controller that mitigates Flash wait-state penalties at 80 MHz. The 16 KB instruction cache and prefetch module accelerate tight loops in DSP-style filtering and motor-control code, while the bus matrix keeps USB, CAN, DMA, and the PMP concurrent.
Typical applications include USB peripherals, industrial CAN nodes, low-cost graphics HMI panels, audio playback with I2S DACs, and bridges between legacy industrial sensors and modern USB hosts. It is also used in entry-level embedded web servers and POS terminals.
When designing, validate that the 3.3V rail meets the 2.3-3.6V supply window, keep oscillator traces short, and reserve a robust decoupling network around the VDD/VSS pairs. Use Microchip MPLAB Harmony or MCC for peripheral configuration to avoid register-level misconfiguration.

کاربردهای معمول
PIC32MX575F256H-80I/PT مناسب است برای 6 کاربردs: USB Industrial Peripherals and Bridges, CAN 2.0b Industrial Nodes, Low-Cost Graphics HMI Panels, I2S Audio Playback Devices, Entry-Level Embedded Web / TCP-IP Servers, POS Terminals and USB Barcode Scanners.
USB Industrial Peripherals and Bridges
The PIC32MX575F256H-80I/PT fits USB industrial peripherals because it integrates USB 2.0 full-speed OTG, 80 MHz MIPS32 M4K performance, and 64 KB SRAM for class-specific descriptors. Its 256 KB Flash holds full USB stacks (CDC, HID, vendor-class) plus application logic. Designers place a 48 MHz crystal on the OSC1/OSC2 pins and use the internal PLL to drive the 80 MHz USB-compatible clock, avoiding external clock chips. Unlike bare 8-bit MCUs that need an external PHY, this part implements USB on-chip, reducing BOM and PCB area while keeping industrial -40C to +85C operation.

CAN 2.0b Industrial Nodes
On CAN 2.0b industrial nodes, the PIC32MX575F256H-80I/PT provides hardware CAN, 10-bit ADC for sensor sampling, and 256 KB Flash for protocol stacks such as CANopen or J1939. The integrated CAN module handles bit timing and acceptance filters, offloading the CPU for deterministic 1 Mbps bus arbitration. Compared with external CAN controllers, the on-chip engine reduces interrupt latency and saves board space. Pair the device with a high-speed CAN transceiver on the CANTX/CANRX pins and add TVS diodes for ISO 7637-2 surge compliance in 24V industrial environments.

Low-Cost Graphics HMI Panels
The PIC32MX575F256H-80I/PT drives low-cost graphics HMI panels using its parallel master port (PMP), which supports 8/16-bit interfaces to TFT controllers and external graphics RAM. At 80 MHz, the M4K core refreshes QVGA panels without DMA starvation while reserving CPU bandwidth for touch and logic layers. The 64 KB SRAM accommodates small framebuffers and font tables; 256 KB Flash holds GUI libraries and asset tables. Place the part adjacent to the PMP connector with matched-impedance traces to keep EMI low, and add a 10uF + 0.1uF decoupling network near each VDD/VSS pair.

I2S Audio Playback Devices
For I2S audio playback devices, the PIC32MX575F256H-80I/PT provides a dedicated I2S peripheral that streams 16/32-bit PCM data to external DACs without CPU copy loops. The 64 KB SRAM buffers multi-second audio clips, and the 256 KB Flash stores compressed audio assets and codec state machines. A 48 kHz sample rate consumes roughly 2 KB/s of I/O, leaving ample headroom for UI handling. Add a low-jitter oscillator reference for the I2S bit clock and isolate the analog audio ground from the digital MCU ground with a ferrite bead to keep noise out of the audio path.

Entry-Level Embedded Web / TCP-IP Servers
For entry-level embedded web servers, the PIC32MX575F256H-80I/PT runs lightweight TCP/IP stacks (e.g., Microchip MLA TCP/IP or Harmony Net) within its 256 KB Flash, while 64 KB SRAM holds a handful of simultaneous sockets. The 80 MHz core sustains 1-2 Mbps throughput on Ethernet-over-SPI or external MAC interfaces. The 10-bit ADC monitors analog sensor inputs reported over HTTP. Use external SPI Ethernet controllers for wired connectivity, and add watchdog + brown-out configuration per the family datasheet 60001156J to keep the device recoverable in field deployments.
پیشنهادی
POS Terminals and USB Barcode Scanners
The PIC32MX575F256H-80I/PT fits POS terminals and USB barcode scanners because it combines USB host/device OTG, ample Flash for HID stacks, and I2S for beeper/prompt tones. The PMP peripheral can drive a small character LCD or OLED, while the 10-bit ADC reads battery or supply telemetry. At 80 MHz, the device decodes 1D/2D barcodes at typical scanner speeds without DMA bottlenecks. Place the MCU close to the USB connector with a 90-ohm differential pair for DP/DM, and add ESD protection arrays on external pins to survive hot-plug events.

یادداشت‌های طراحی
Estimated: at 80 MHz full-load CPU plus USB + CAN active, total VDD current is approximately 70 mA. With 3.3V rail and 90% DC-DC efficiency, derate the supply to 250 mA. Place 10uF bulk + 0.1uF + 10nF decoupling near each VDD/VSS pair. For analog (AVDD/AVSS), use a ferrite bead to isolate digital switching noise from the 10-bit ADC reference. The internal 1.8V core LDO does not need an external capacitor beyond 1uF per datasheet recommendation.
Keep the 48 MHz primary crystal traces (OSC1/OSC2) short and symmetric, and place the load capacitors within 5 mm of the pins. Route the USB DP/DM pair as a 90-ohm differential with ground reference on both sides; add a 47 nF + 0.1 uF AC-coupling network if the host expects full-speed edge rates. Maintain continuous ground pour under the TQFP-64 footprint to dissipate heat and provide a low-impedance return path.
Do not exceed 3.6V on any VDD/AVDD pin, even during hot-plug or USB bus-powered transients - use a TVS array on VBUS. Configure the brown-out reset (BOR) and watchdog timer (WDT) early in firmware so a stalled core recovers without external intervention. Per Microchip errata practice, consult the device-specific errata document for any PIC32MX575 silicon revisions before final production. The VUSB pin requires a 0.47 uF decoupling cap; omitting it causes USB enumeration failures.
