Overview

In this Tutorial, We Learn All About the Raspberry Pi Pico W Microcontroller. In this Board, Raspberry Pi Funduction Used The RP2040 Microcontroller.

Raspberry Pi Pico W is a low-cost Arm Microcontroller, We easily program the Board Using C/C++ And MicroPython.

Many microcontrollers in the Market board are Available, Like Arduino, Esp8266, Esp32, PIC, STM32, LPC2148 and Other AVR Microcontrollers.

The Raspberry Pi Computer is High cost Around 6000-15000 Rupes In India. That’s why the Raspberry Pi Function released their low cost assertive competitive Raspberry Pi Pico And Raspberry Pi Pico W With RP2040-based Dual core Arm Cortex-M0+ Microcontroller.

Why RP2040 Microcontroller

In Earlier All The Raspberry Boards like Rpi Zero, Raspberry Pi 3, Raspberry Pi 3+ And Raspberry Pi 4 featured Broadcom Process Like BCM2835, BCM2836, BCM2711 Etc.

The RP2040 Chip Was Announced on 21st January 2021 And the Fist Processer was Designed By the Raspberry Pi Foundation.

The RP2040 is a 32-bit dual ARM Cortex-M0+ microcontroller. The Processor is a low-cost microcontroller And Costs Around 700Rupes. The chip is 40nm silicon in a 7×7 mm QFN-56 Package.RP2040 Contains 2 ARM Cortex-M0+ Cores Clocked at 133 MHz together with 264 KB of RAM. Program memory is external and supports up to 16 MB.

Full Form Of (RP2040)

RP means: Raspberry Pi
Number 2 means: Processor Cores as it is a Dual-Core Microcontroller.
Number 0 means the type of Processor Core as it is ARM Cortex-M0+.
Number 4 means: Represents On-chip RAM. RP2040 has 264 KB of RAM.
Number 0 means: Represents On-chip Flash. As there is no on-chip flash.

Features

30 GPIO pins
133MHz Dual ARM Cortex-M0+ Cores
264kB SRAM
Support for up to 16MB of off-chip Flash memory.
DMA controller
On-chip Programmable LDO(Low-dropout_regulator) To Generate Core Voltage
2 on-chip PLLs
