Whadda ATmega328P Microcontroller IC with Arduino Uno Bootloader 16MHz

Whadda ATmega328P Microcontroller IC is a low-power CMOS 8-bit AVR microcontroller supplied pre-configured with the Arduino Uno bootloader and a 16 MHz crystal oscillator. It can serve as a replacement for the microcontroller in an Arduino Uno or as the core component of custom electronics projects.

Overview

The ATmega328P is built on an enhanced RISC architecture and can execute instructions in a single clock cycle, with throughput close to 1 MIPS per MHz. Its on-board memory comprises 32 KB of Flash memory for program code, 2 KB of SRAM for data during operation, and 1 KB of EEPROM for non-volatile parameter storage.

Key Features

• Pre-loaded Arduino Uno bootloader, allowing code upload over a standard USB cable using the Arduino IDE without an external hardware programmer
• 23 programmable I/O lines for connecting sensors, actuators, displays and communication modules
• Supplied with a 16 MHz crystal oscillator to provide the clock signal for stable operation and accurate timing
• CMOS design with low power consumption, suitable for battery-powered and energy-sensitive applications
• Available in 28-pin PDIP through-hole format for breadboards and prototyping, and 32-lead TQFP and QFN/MLF surface-mount packages for compact PCB designs

Dimensions and Weight

Width 3.3, depth 1.5 and height 4.3, as supplied, with a product weight of 40 g.

Applications

This IC suits repairing an existing Arduino board, building a custom development platform, or integrating microcontroller functionality into a new product. Its through-hole and surface-mount package options support both prototyping and compact PCB designs.

Choose the Whadda ATmega328P Microcontroller IC when you need a microcontroller with a pre-loaded Arduino Uno bootloader and an included 16 MHz crystal oscillator for straightforward programming and development.
