Applications BriefTMS4416/TMS4500A EVALUATION BOARDThis application note illustrates memory system implementation using the TMS4416/TMS4500A evaluationboard (Photo shown in Figure 1). The board measures 3" X 5.5" and is populated with a TMS4500A DRAMcontroller imd 16 TMS4416s (16K X 4 Dynamic RAMs); this system provides for 128K bytes of static appearingmemory and requires a single 5-volt supply. The interconnection bus at the board edge and the flexibility ofthe TMS4500A makes the board adaptive to almost any system. This board was developed by TexasInstruments to allow construction of several processor systems without redesign of the memory section for eachsystem. It is beyond the scope of this article to cover every microprocessor interface, although several popularmicroprocessor interfaces are covered in the TMS4500A User's Manual.co.~ca..
