Size of the storage memory and RAM can vary significantly. Some systems run in 16 KB of Flash and 4 KB of RAM with a CPU operating at 8MHz, other systems can rival contemporary computers.[5] These space requirements lead to more work being done in C or embedded C++, instead of C++. Interpreted languages like BASIC and Java are not used.http://www.automateandvalidate.com
