Typical figures are at 25°C and are for design aid only; not guaranteed and not subject to production testing
Note: Because of internal clock re-synchronization one single additional requirement is recommended in order to produce a
simultaneous instruction execution in a multi-chip configuration: WR rising edge has to be 20 to 20 + tWL(cK) nsec late relative
to clock falling edge.
