PIC32MX575F256LT-80V/PT 概要
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and integrated peripherals including ADCs, timers, and communication controllers. The PIC32MX5XX/6XX/7XX family sits in the hierarchy as: microcontroller -> embedded computing -> semiconductor, and bridges 8-bit PIC16/PIC18 simplicity with 32-bit performance, targeting USB/CAN-enabled industrial, medical, and consumer devices.
Key features of the PIC32MX575F256LT-80V/PT include 83 general-purpose I/O lines, 16-channel 10-bit ADC at 1 Msps, multiple DMA channels for low-CPU-overhead data movement, hardware RTCC, 5 timer/counter modules, and peripheral pin select (PPS) for flexible signal routing. The "V" suffix denotes the V-temp grade of -40C to +105C operation, suitable for industrial environments; the "T" denotes tape-and-reel packaging; and the "/PT" denotes the 100-pin TQFP package.
Architecturally, the PIC32MX575 uses the MIPS32 M4K core with 5-stage pipeline, single-cycle multiply, and hardware divide. It supports 32-bit instructions and 32-bit data paths while remaining code-compatible with legacy 16-bit PIC instruction extensions. The M4K core combined with tightly-coupled DMA offloads data transfers from the CPU for deterministic latency.
Typical applications include USB peripherals (HID, CDC, mass storage), CAN-connected industrial nodes, motor control (BLDC, stepper, servo), graphical HMI with external LCD controllers, and sensor data acquisition. The integrated USB-OTG and CAN make it especially suitable for industrial automation, medical instrumentation, and automotive body/comfort subsystems.
When designing with this part, mind the 2.3V-3.6V supply range and ensure decoupling caps are placed per the datasheet. PPS requires careful pin mapping during firmware bring-up; verify PPS assignments in code review to avoid silent peripheral failures.

設計ノート
Decouple all VDD/AVDD pins with 100 nF ceramic caps placed as close to the pins as possible (per Microchip datasheet DS60001156K). Add a single 10 uF bulk tantalum or ceramic cap on each major supply rail. The PIC32MX575 has multiple VDD pins; missing any one can cause intermittent resets or ADC accuracy degradation. Place an LC or ferrite bead on analog AVDD to isolate from digital switching noise.
Peripheral Pin Select (PPS) mapping must be configured in firmware before using remappable digital peripherals. A peripheral assigned to an unmapped pin will appear silent - no error, no output. Always declare PPS mappings at startup and verify them in code review. Also note that analog functions bypass PPS and must be wired to dedicated analog pins.
The 100-pin TQFP has a 0.4 mm pitch requiring careful PCB layout. Use 4-layer stack-up with continuous ground plane under the MCU to provide reference for high-speed signals and thermal dissipation. USB D+/D- traces must be 90 ohm differential with matched length; route over an unbroken ground plane to maintain impedance.
The 80 MHz system clock generates harmonics up to 400+ MHz. Keep clock traces short and shielded with ground vias. If using external crystal, place the load caps within 3 mm of the OSC1/OSC2 pins and keep the crystal case grounded. Avoid routing high-speed signals (USB, SPI at >10 MHz) under the MCU or near the ADC inputs.
