There are few inventions in the field of electronics that have influenced its development as strongly as microcontrollers. The first milestone was certainly the replacement of electron tubes with transistors and semiconductor diodes. It initiated a series of key changes for the entire development of electronics. One of the characteristics of this technological leap forward was the progressive miniaturization of electronic circuits and increasing their capabilities. This in turn made it possible to introduce integrated circuits that evolved from analogue to digital. It was the digital integrated circuits that enabled the creation of microcontrollers, which are now the basis for most of the devices we use on a daily basis. In our Botland shop we have prepared many types of microcontrollers from all the best known manufacturers. We still make every effort to expand our list with products that are of the highest quality and at an affordable price. If you have any questions, please contact our technical department, which will be more than happy to help you.

The history of the microcontrollers
The microcontroller was invented at Texas Instruments in the early 1970s, at the same time as the first microprocessor was invented by Intel. The first microcontrollers were simply microprocessors with memory such as RAM and ROM. Later, microcontrollers evolved into a wide range of devices suitable for specific embedded system applications in devices such as cars, wireless phones and household appliances. During the 1990s, the market welcomed the microcontrollers with ROM programmable and electrically erasable memories, such as flash memory. These microcontrollers could be programmed, erased and reprogrammed using only electrical signals. Many current microcontrollers, such as those available from Microchip and Atmel, incorporate flash memory technology. Nowadays, in addition to general-purpose devices, specialized microcontrollers are produced in areas such as automotive, lighting, communications and low-power consumer devices. In 2010, Atmel announced a flash microcontroller in a package measuring 2 mm by 2 mm. These tiny microcontrollers are small and inexpensive enough to be used in products such as toys and toothbrushes.
Microcontroller design - What are the most important parameters of microcontrollers?
Currently there is a huge number of different types of microcontrollers on the market. IC manufacturers take care to provide many thousands of microcontroller models that differ in every possible parameter. Beginner programmers may have the impression that such a wide selection makes it impossible to choose anything. However, this is not true. A wide range of microcontrollers with different parameters allows you to choose the products that are perfectly fitted to every project. If your goal is to achieve measurement or control applications, small 8-bit (AVR, PIC, STM8) or 16-bit MSP430 microcontrollers will work perfectly. If your project is more demanding, it is recommended to use more complex 32-bit microcontrollers, which have more varied peripherals. Furthermore, in such microcontrollers the available RAM and FLASH memory is significantly increased. You can also use the most advanced microcontrollers, which allow you to display high quality graphics and perform floating point operations. An example of such is the STM32 microcontroller.
