PIC32MX575F256LT-80V/BG 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash for program code and SRAM for data), and a rich set of peripherals such as timers, communication interfaces, and analog blocks. The PIC32 family sits within the broader taxonomy: microcontroller -> embedded processor -> semiconductor -> integrated circuit. Within Microchip's portfolio, PIC32MX5xx devices target mainstream 32-bit embedded designs that exceed 8-bit PIC16/PIC18 capability without the cost of higher-tier PIC32MZ parts.
Key features of this device include 83 general-purpose I/O lines, multiple DMA channels for peripheral-to-memory transfers without CPU intervention, PWM outputs for motor and power control, and a 10-bit ADC with 1 Msps sampling. It also provides two I2C, two SPI, and two UART interfaces for flexible peripheral connectivity.
Technically, the MIPS32 M4K core delivers 1.56 DMIPS/MHz and supports the MIPS16e instruction set for code density. The 5-stage pipeline and hardware multiply/divide unit accelerate DSP-style operations. The 80 MHz operation yields 105 DMIPS, while the USB-OTG and CAN peripherals are critical for industrial networking and consumer device bridging.
Typical applications include USB peripherals, CAN-connected industrial nodes, graphical user interfaces with external LCD controllers, motor control loops, and consumer audio devices. Designers select this part when balancing Flash size, peripheral set, and cost. The TFBGA package supports compact PCB layouts but requires careful routing due to the 0.8 mm pitch.
When designing, ensure proper decoupling near each VDD/VSS pair, and verify the 80 MHz timing closure with the chosen compiler optimization. The -80V suffix indicates the 80 MHz speed grade and 'V' temperature range; the 'BG' suffix indicates the 121-pin TFBGA package and tape-and-tray packaging.

主な用途
PIC32MX575F256LT-80V/BG の用途: 6 件s: USB Human Interface Device (HID), CAN Bus Industrial Nodes, Graphical User Interface Controller, Motor Control and PWM Drives, Portable Data Acquisition, Consumer Audio Devices.
USB Human Interface Device (HID)
The PIC32MX575F256LT-80V/BG's integrated USB 2.0 Full-Speed OTG controller makes it ideal for USB HID peripherals such as keyboards, mice, game controllers, and custom input devices. The 80 MHz MIPS32 M4K core delivers 105 DMIPS, sufficient for HID class drivers plus application logic. With 256 KB Flash, the part accommodates USB stacks (Microchip's MLA library) alongside user firmware, and 64 KB SRAM buffers HID reports comfortably. The 16-channel 10-bit ADC supports analog inputs like joystick axes or potentiometers.
おすすめ
CAN Bus Industrial Nodes
The integrated CAN 2.0B controller positions the PIC32MX575F256LT-80V/BG for CAN-connected industrial nodes including factory sensors, motor controllers, and building automation endpoints. With -40C to +105C industrial temperature range and 83 GPIO, the part drives multiple sensor channels and CAN transceivers. The DMA controller offloads CAN message buffering from the CPU, freeing 105 DMIPS for application logic. The 256 KB Flash accommodates CANopen or DeviceNet protocol stacks with room for application code.
おすすめ
Graphical User Interface Controller
With 256 KB Flash, 64 KB SRAM, and five PWM channels, the PIC32MX575F256LT-80V/BG can drive external LCD controllers for graphical user interfaces in appliances, instrumentation, and HMI panels. The parallel PMP (Parallel Master Port) interface connects to TFT displays at up to 80 MHz system clock. The DMA channels transfer framebuffer data without CPU intervention, leaving MIPS for touch processing and menu logic. The 10-bit ADC reads touch-screen resistive layers directly.
おすすめ
Motor Control and PWM Drives
The five PWM channels, quadrature encoder interface, and 80 MHz computational throughput make the PIC32MX575F256LT-80V/BG well suited for brushed DC and stepper motor control. The 10-bit ADC samples motor current at 1 Msps for closed-loop control, and DMA moves conversion data without CPU intervention. Sensorless and sensored BLDC algorithms run comfortably at 105 DMIPS. Industrial temperature rating and 83 GPIO support multi-axis systems with limit switches and fault inputs.
おすすめ
Portable Data Acquisition
The PIC32MX575F256LT-80V/BG's 16-channel 10-bit ADC, 256 KB Flash for logging firmware, and 64 KB SRAM for sample buffering suit portable data loggers and instrumentation. DMA-driven ADC sampling at 1 Msps captures multi-channel waveforms without CPU load. USB OTG enables direct file transfer to PCs or USB sticks. Operating voltage down to 2.5V supports battery-powered designs. The compact 121-pin TFBGA (10x10 mm) package minimizes PCB footprint for handheld instruments.
おすすめ
Consumer Audio Devices
The PIC32MX575F256LT-80V/BG integrates I2S support through peripheral libraries, USB OTG for audio streaming, and 256 KB Flash for codec firmware, making it suitable for USB speakers, headphone amps, and consumer audio peripherals. The two I2C buses control audio DACs and amplifiers, while the two SPI buses drive external Flash for sample storage. Five 16-bit timers generate accurate audio clock domains. The DMA channels move audio samples with low CPU overhead, leaving MIPS for DSP effects.

設計ノート
Place a 10 uF bulk capacitor and a 0.1 uF decoupling capacitor within 5 mm of each VDD/VSS pair on the PIC32MX575F256LT-80V/BG. The 121-pin TFBGA package distributes VDD/VSS across all four edges; missing decoupling causes erratic operation at 80 MHz. AVDD (analog supply) requires a ferrite bead or 10 ohm resistor from VDD plus its own 0.1 uF + 10 uF capacitor network for low ADC noise.
The 121-pin TFBGA (0.8 mm pitch) requires 4-layer PCB with microvia-in-pad for reliable assembly. Escape routing between balls needs 0.4 mm trace width with 0.4 mm spacing. The 10x10 mm package fits a 50 mm x 50 mm 4-layer PCB with all peripherals. Use laser-drilled vias or filled-and-capped vias on BGA pads to reduce solder voiding and improve thermal dissipation.
Do not enable the JTAG pins as GPIO unless JTAG debugging is disabled in configuration bits - leaving JTAG enabled consumes 5 mA additional current and blocks the pins. Configure the oscillator mode (FRC, POSC, SOSC) in configuration bits before code execution. The USB D+/D- lines require 15 kohm pull-downs on the device side per USB spec; missing pull-downs cause enumeration failures.
At 80 MHz full activity, the PIC32MX575F256LT-80V/BG consumes approximately 70 mA (3.3V x 70 mA = 230 mW). The TFBGA package has theta_JA around 30 C/W, giving a 7C temperature increase above ambient at room temperature. No heatsink is required for typical applications, but industrial enclosures above 70C ambient should include thermal vias under the center balls for additional dissipation.
