TA = -40 to +85 °C
for SAF-C165-L25M
C
L (for PORT0, PORT1, Port 4, ALE, RD, WR, BHE, CLKOUT) = 100 pF
C
L (for Port 6, CS) = 100 pF
Notes
1) These timings are given for test purposes only, in order to assure recognition at a specific clock edge.
2) Demultiplexed bus is the worst case. For multiplexed bus 2TCL are to be added to the maximum values. This
adds even more time for deactivating READY.
The 2tA and tC refer to the next following bus cycle, tF refers to the current bus cycle.
