Appendix A: Low-Frequency Mode
5.1
Asynchronous Access
Depending on the random access frequency two cases are distinguished:
High Frequency Mode (
≥
100 kHz):
There are no
t
RC
max. time nor CS1/OE max. low time restrictions during subsequent random read or write
accesses.
Low Frequency Mode (< 100 kHz):
There are no
t
RC
max. time nor CS1/OE max. low time restrictions if all control signals (CS1, OE, WE, UB/LB)
follow the modified timing as shown below, see attached timing diagram and timing table. There is no extra mode
register setting necessary.
