General Description The SH79F081A is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch structure, that helps the SH79F081A can perform more fast operation speed and higher calculation performance, if compare SH79F081A with standard 8051 at same clock speed. The SH79F081A retains most features of the standard 8051. These features include inter...
