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 flow in a multi-chip configuration: The RD rising edge has to be 20 to 20 + tWL(CK) ns late relative to

clock falling edge.
