R-535J  
The R-535J accepts the 80C535 or 80C515 microcontrollers, which are enhanced 8032 processors in the 68-pin PLCC format. The 80C535 includes a Boolean processor, watchdog timer, A / D converter, and has 28 total I / O bits available. The system bus is available on two headers where the address and data lines of the processor are de-multiplexed. The system bus facilitates interfacing the R-535J to external memory-mapped input / output devices. This board is ideally suited for those wishing to use the 8031, but who need more I / O, or wish to use analog-to-digital conversion. Its small size and low cost make the R-535J perfect as a training board and for embedded control.
