CYD04S36V18
Key Features
- PROBLEM DEFINITION The 256-Ball FBGA package substrate design has the ZQ0L pin shorted to ZQ1L and ZQ0R shorted to ZQ1R. The ZQ1L and ZQ1R pins are not internally connected to the die for the affected devices; therefore, when resistors are connected to these pins to ground, the effective output driver impedance for each port is halved.
- PARAMETERS AFFECTED Effective output driver impedance controlled by the VIM circuitry.
- TRIGGER CONDITION(S) If the designer populates resistors for
