Timing Conditions
Unless specified otherwise, the following conditions are true for all timing measurements. All characteristics are
= 0 V over an operating temperature of 0 ° C to +70 ° C. Those characteristics
specified at V
= 2.3 - 2.7 V and V

SS
marked with a # will be significantly different for 13 MHz mode because the EXPCLK is provided as an input rather
than generated internally. These timings are estimated at present. The timing values are referenced to 1/2 V
.
