In this article, we are going to discuss the ATMEGA328P-AU microcontroller. This electronic part is manufactured by Microchip Technology and is available to buy on from authorised Microchip distributors including Farnell & Schukat who have this electronic part in stock. This high-performance product has much to offer, as we will now explain.

ATMEGA328P-AU by Microchip Technology


The ATMEGA328P-AU is a microcontroller of the highest industry standard. A microcontroller sits within the internal framework of so many machines that we use on a daily basis. These range from computer keyboards, printers, photocopiers and fax machines to washing machines, dishwashers and microwave ovens. Indeed, a microcontroller acts as the central hub for these and many other devices to operate. And to achieve the best possible output from these machines, we highly recommend the ATMEGA328P-AU as your microcontroller of choice.

ATMEGA328P-AU Technical Specifications

The ATMEGA328P-AU is an 8-bit AVR RISC-based microcontroller. It brings together 32KB of ISP flash memory and read-while-write capabilities. Amongst its make-up are a 1024B EEPROM plus 2KB SRAM, 23 general purpose I/O lines and 32 registers providing general purpose. Furthermore, it has interrupts on an internal and external level, a serial programmable USART and a 6-channel 10-bit A/D converter, with eight channels coming as part of TQFP and QFN/MLF packages. Not to mention that it operates at a rate of between 1.8 volts and 5.5 volts. Additionally, this microcontroller has power-saving functionality through five software selectable modes. And not forgetting its watchdog timers to set limits for particular processes and high-speeds, all achievable during one operating session.

Other Notes

Alongside these technical points, the ATMEGA328P-AU is easy to install and program by following the instructions included with the product. Effectively acting as a mini-computer, this is an intelligent and innovative product that enhances the value of any machinery using it. Note that the ATMEGA328P-AU is of a small physical scale, making it delicate when it comes to durability. All of which makes it even more impressive that this microcontroller is able to perform so many tasks to a first-class operational standard.

Why You Need The ATMEGA328P-AU

Let’s face it; all of the machines that we regularly use are there to serve a purpose. So, if their performance levels consistently drop, it can be a major source of frustration. Especially when trying several different machines of the same nature, only for familiar issues to arise. But that’s where the ATMEGA328P-AU comes into play. By serving as the machine’s nerve centre, this microcontroller enhances the quality of its surroundings, thus impacting a machine’s usage. As a result, the life span and performance levels of the machine in question increase accordingly. And the ATMEGA328P-AU itself can last a long time, so you can reap the benefits for many years to come. So, don’t settle for inferior quality or low performance; go for the best option available and choose the ATMEGA328P-AU microcontroller.
