Remarks 1. The rise and fall times (tr and tf) of input signals are rated at 15 ns or less. When using a fast system
cycle time, the rated value range is either (tr + tf)
≤ (tCYC6–tEWLW–tEWHW) or (tr + tf) ≤ (tCYC6–tEWLR–tEWHR).
2. All timing is rated based on 20% or 80% of VDD.
3. tEWHW and tEWLW are rated as the overlap time when /CS1 is at low level (CS2 = H) and E is at high
level.
