.. _rp2_general: 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 For detailed technical specifications, please refer to the `rp2040-datasheet `_ 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 For detailed technical specifications, please refer to the `rp2350-datasheet `_
