NOTES
1 See AC Timing Waveforms for waveforms and definition
2 Measured at VIH for high time VIL for low time
3 Only required to guarantee ICC Maximum limits are bounded by TC TCH and TCL
4 Specified for a 50 pF load see Figure 13 for capacitive derating information
5 Specified for a 50 pF load see Figure 14 for rise and fall times outside 50 pF
6 See Figure 14 for rise and fall times
7 TCHOV1 applies to BHE (RFSH) LOCK and A19 16 only after a HOLD release
8 TCHOV2 applies to RD and WR only after a HOLD release
9 Setup and Hold are required to guarantee recognition
10 Setup and Hold are required for proper operation
