Short summary of tech specs! The RP2040 microcontroller is manufactured on a 40 nm silicon process in a 7x7mm
QFN-56 SMD package. The key features include:
Description of general structure of the port (it's built on top of the APIs * 133 MHz dual ARM Cortex-M0+ cores (overclockable to over 400 MHz)
provided by the Raspberry Pi SDK). * 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
