A | Page 6 of 32 Parameter Min Typ Max Unit Test Conditions/Comments WRITE OPERATION t11 0 ns CS falling edge to SCLK falling edge setup t12 30 ns Data valid to SCLK rising edge setup time t13 25 ns Data valid after SCLK rising edge hold time t14 50 ns SCLK high pulse width t15 50 ns SCLK low pulse width t16 0 ns CS rising edge after SCLK rising edge hold time 1 Sample tested during initial release to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of DVDD) and timed from a voltage level of 1.6 V. See Figure 2 and Figure 3. 2 These numbers are measured with the load circuit of Figure 4 and defined as the time required for the output to cross the VOL or VOH limits. 3 This specification is relevant only if CS goes low while SCLK is low. 4 These numbers are derived from the measured time taken by the data output to change 0.5 V when loaded with the circuit of Figure 4. The measured number is then extrapolated back to remove effects of charging or discharging the 50 pF capacitor. This means that the times quoted in the Timing Specifications are the true bus relinquish times of the part and as such are independent of external bus loading capacitances. TIMING DIAGRAMS Figure 2.
