This article introduces RP2040 low-power strategies to cut dynamic and static power, including clock gating, clock switching and DORMANT deep sleep mode.

This article covers RP2040's on-chip core regulator, its adjustable voltage range, three operation modes, ROK indicator and configuration registers.

This article introduces RP2040's multi-rail power supply system and several practical power supply wiring schemes.

This article introduces RP2040’s power-on boot sequence, covering hardware initialization and BootROM-driven Flash/USB boot modes.

This article defines address mapping, register mapping and remapping, which establish address indexing rules for all internal chip resources.

This article explains RP2040 DMA controller, its working modes, channel chaining, DREQ trigger mechanism and interrupt configuration.

This article details the Cortex-M0+ core adopted by RP2040, including its main features, supporting modules and applicable embedded scenarios.

This article introduces RP2040's dual-core processor subsystem, covering SIO, interrupts, event signals and SWD debug architecture.

This article explains RP2040's bus architecture and address mapping that govern internal data transmission and resource access.

This article defines pin multiplexing and explains how RP2040 GPIOs switch between different peripheral functions via function selection tables.

This article explains pin mapping and its vital roles in hardware design, coding and resource allocation using RP2040 as an example.

This article explains how to learn chips via block diagrams and introduces each functional module of RP2040 with a vivid miniature factory analogy.

This article introduces the naming rules of Raspberry Pi RP-series MCUs and explains how to decode core hardware parameters from RP2040 and RP2350 model numbers

This article explains XIP, a technology allowing MCUs to execute code directly from Flash instead of copying it to RAM, using Raspberry Pi Pico as an example.

UF2 (USB Flashing Format) developed by Microsoft is used for Raspberry Pi Pico firmware.
