Hi all,

I am trying to make sine wave ups with 89cxx.
While surfing i found similar project using PIC
micro http://www.laogu.com/download/ups.pdf

Can any one guide me which 89cxx Derivative is best suitable for this task?
Can 89c51rd2 "PCA" can give similar performance.I will require 32 interupts per 1/2 cycle of 50hz & need sufficient time to do A D conversion ,also some math?

Regards
