Part Description
The RP2040 by Raspberry Pi is an ARM® Cortex®-M0+ microcontroller featuring a 32-Bit Dual-Core processor capable of running at 133MHz. It supports external program memory and integrates a comprehensive set of peripherals including I2C, IrDA, QSPI, SPI, UART/USART, USB, and more. This IC is packaged in a 56-pin QFN (7x7) with exposed pads, making it ideal for surface-mount applications and high-density designs. Additional features include integrated data converters (4x12b SAR A/D), 264K x 8 RAM, and robust connectivity along with peripherals like brown-out detection, DMA, I2S, LCD control, POR, PWM, and Watchdog Timer. Note that the image is a representation only; exact specifications must be confirmed via the product datasheet.

Detail.

Considering.

USB_DM and USB_DP are the USB 2.0 data lines. They form a bidirectional differential pair used for signaling between a USB host and device.
Meaning in your schematic
  • USB_DM: D− (the inverting line of the USB differential pair)
  • USB_DP: D+ (the non-inverting line of the USB differential pair)
Quick notes
  • Function: Carry USB data as a differential signal; they do not supply power.
  • Signaling: Full-speed uses differential signaling at 12 Mbps; pair impedance is typically 90 Ω differential.
  • Identification: A 1.5 kΩ pull-up on D+ indicates a full-speed device (on D− for low-speed). Many MCUs handle this internally.
  • Layout: Route as a tightly coupled, length-matched differential pair with a solid ground reference and minimal stubs/vias.
