Manufacturer:TI Description:Programmable ground control is useful for internal chip signal management. The output buffers of the Fast Func- tion Blocks have an impedance of around 7 Ω when switching high to low, where the High Density Function Blocks impedance is around 14 Ω. Since this low imped- ance is negligible compared to the impedance of the pin inductance when output current transients occur, a rea- sonable ground connection can be made by driving unused output pins low and physically attaching them to external ground. The XC73144 architecture permits the automatic assignment of external ground signals to all Macrocells that are not declared as primary outputs or I/Os. Note that the logical function of the buried Macrocell is fully preserved, while its output driver is driving low and physically attached to ground. Should designers not wish to employ programmable ground control, they need only declare all such pins as primary I/Os whether they will be attached externally or not. |
