Microprogram Controller  
August 19, 2008  
Description  
The IA2910A is a form, fit and function compatible part to the AMD 2910A microprogram  
controller. The IA2910A is an address controller which will sequence through a series of  
microinstructions contained in a ROM or PROM. There are four sources of addresses from which  
the IA2910A may select. The first is a direct data bus (DIN) input, which is straightforward. The  
second is an internal address register. This register contains data loaded during a previous  
microinstruction. The third source is a program counter register, which generally contains the  
previous address incremented by one. The final source of addresses is a nine word deep stack  
register which gives the capability to execute nested subroutine linkages. All internal registers are  
clocked on the rising edge of the clock input (CLK). An OEn input enables the YOUT output bus  
to be tri-stated. A block diagram is shown in Figure 1.
