should we use 8255 programmable peripheral interface also. That part was never designed for use with the 8051; it is obsolete, and it has been obsolete for very many years now! Choose a modern derivative with sufficient IO for your requirements - modern derivatives with on-chip flash mean you don't have to use up ports for an external memory interface. Or, if you want to design-in an obsolete part, why not at least design-in a modern one - like a Triscend E5! http://www.keil.com/dd/cl/Triscend/8051.htm |
