.. _rp2_general: General information about the RP2xxx port ========================================= The rp2 port supports boards powered by the Raspberry Pi Foundation's RP2xxx family of microcontrollers, most notably the Raspberry Pi Pico that employs the RP2040. Technical specifications and SoC datasheets ------------------------------------------- For detailed technical specifications, please refer to the `datasheets `_ 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 togenerate core voltage * 2 on-chip PLLs to generate USB and core clocks * 30 GPIOpins, of which 4 can optionally be used as analog inputs The peripherals include: * 2 UARTs * 2 SPI controllers * 2 I2C contollers * 16 PWM channels * USB 1.1 controller * 8 PIO state machines
