General information about the RP2xxx port#

The rp2 port supports boards powered by the Raspberry Pi Foundation's RP2xxx family of microcontrollers, including the RP2040 and RP2350.

Technical specifications and SoC datasheets#

RP2040#

The RP2040 microcontroller is manufactured on a 40 nm silicon process in a 7x7mm QFN-56 SMD package.

The key features include:

• 133 MHz dual ARM Cortex-M0+ cores (overclockable to over 400 MHz)
• 264KB SRAM in six independent banks
• No internal Flash or EEPROM memory (after reset, the bootloader loads firmware from either the external flash memory or USB bus into internal SRAM)
• QSPI bus controller, which supports up to 16 MB of external Flash memory
• On-chip programmable LDO to generate core voltage
• 2 on-chip PLLs to generate USB and core clocks
• 30 GPIO pins, of which 4 can optionally be used as analog inputs

The peripherals include:

• 2 UARTs
• 2 SPI controllers
• 2 I2C controllers
• 16 PWM channels
• USB 1.1 controller
• 8 PIO state machines

RP2350#

The RP2350 microcontroller is manufactured on a 40 nm silicon process and is available in QFN-60 (RP2350A) or QFN-80 (RP2350B) packages.

The key features include:

• Dual-core Arm Cortex-M33 or Hazard3 RISC-V processors at up to 150MHz
• 520KB on-chip SRAM
• Support for up to 16MB of off-chip Flash memory via QSPI
• USB 2.0 Full-Speed/Low-Speed controller
• 30 GPIO pins (RP2350A) or 48 GPIO pins (RP2350B)

The peripherals include:

• 2 UARTs
• 2 SPI controllers
• 2 I2C controllers
• 24 PWM channels
• 12 PIO state machines
• HSTX high-speed transmitter
