Cycle time, CLKOUT
Delay time, CLKOUT high to EBADDR valid
Hold time, EBADDR invalid after CLKOUT high
Delay time, CLKOUT high to EBOE fall
Hold time, EBOE rise after CLKOUT high
Delay time, CLKOUT low to write strobe (EBWR) low
Hold time, EBWR high after CLKOUT low
Setup time, EBDATA valid before CLKOUT high (READ)⁽²⁾
Hold time, EBDATA invalid after CLKOUT high (READ)
Delay time, CLKOUT low to EBDATA valid (WRITE)⁽³⁾
Hold time, EBDATA invalid after CLKOUT low (WRITE)
SECONDARY TIMES
Delay, CLKOUT high to EBCS0 fall
Hold, EBCS0 rise after CLKOUT high
Setup time, EBHOLD low to CLKOUT high⁽²⁾
Setup time, EBHOLD high to CLKOUT high⁽²⁾
(1) Not production tested.
(2) Setup time is the minimum time under worst case conditions. Data with less setup time will not work.
(3) Valid after CLKOUT goes low for write cycles.
