6.10 RAM Interface  
The following schematic shows an interface circuit between the Navigator chipset and external ram.  
Comments on Schematic  
The CP is capable of directly addressing 32K words of 16-bit memory. It will also use a 16 bit  
paging register to address up to 32K word pages. The schematic shows the paging and addressing  
for 128KB RAM chips, i.e. 4 pages per RAM chip. The page address decoding is shown for only 6 of  
the 16 possible paging bits. The decoding time from W/R and DS- to the memory output must not  
exceed 18 ns. for a read with no wait states. The writes provide 25 extra ns access time for W/R and  
DS- to reverse the CP data bus.
