Recognised & Supported by
The AT89C51 is an age old 8-bit microcontroller from the Atmel family. It works with the popular 8051 architecture and hence is used by most beginners till date. It is a 40 pin IC package with 4Kb flash memory. It has four ports and all together provide 32 Programmable GPIO pins. It does not have in-built ADC module and supports only USART communication. Although it can be interfaced with external ADC IC like the ADC084 or the ADC0808. To program this microcontroller, you will need an IDE (Integrated Development Environment) like Keil uVision IDE and external programmer hardware MAX232 with RS232 to USB converted to send the data from your personal device to the 8051 microcontrollers. You can use it in DIY projects when you want to learn Atmel programming, you can also replace your Arduino development board when you want a compact and efficient circuit with multiple GPIO pins for I/O interfaces.
