Chapter 1. Introduction
Microcontrollers connect the world of software to the world of hardware. They allow developers to write software which
interacts with the physical world in the same deterministic, cycle-accurate manner as digital logic. They occupy the
bottom left corner of the price/performance space, outselling their more powerful brethren by a factor of ten to one.
They are the workhorses that power the digital transformation of our world.
RP2040 is the debut microcontroller from Raspberry Pi. It brings our signature values of high performance, low cost,
and ease of use to the microcontroller space.
With a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and rich peripheral set
augmented with our unique Programmable I/O (PIO) subsystem, it provides professional users with unrivalled power
and flexibility. With detailed documentation, a polished MicroPython port, and a UF2 bootloader in ROM, it has the
lowest possible barrier to entry for beginner and hobbyist users.
RP2040 is a stateless device, with support for cached execute-in-place from external QSPI memory. This design
decision allows you to choose the appropriate density of non-volatile storage for your application, and to benefit from
the low pricing of commodity Flash parts.
RP2040 is manufactured on a modern 40nm process node, delivering high performance, low dynamic power
consumption, and low leakage, with a variety of low-power modes to support extended-duration operation on battery
power.
