Notes:
1.
See Figure 11, “AC Input/Output Reference Waveform” on page 28 for timing measurements and max
allowable input slew rate.
2.
OE# may be delayed by up to t_ELQV – t_GLQV after CE#’s falling edge without impact to t_ELQV.
3.
Sampled, not 100% tested.
4.
Address hold in synchronous burst mode is t_CHAX or t_VHAX, whichever timing specification is satisfied first.
5.
Please see the latest P30 Spec Update for synchronous burst operation with the TSOP package.
6.
Synchronous read mode is not supported with TTL level inputs.
7.
Applies only to subsequent synchronous reads.

See Figure 11, “AC Input/Output Reference Waveform” on page 28 for timing measurements and
max allowable input slew rate.
2.
This is the recommended specification for all new designs supporting both 130nm and 65nm lithos, or for new designs
that will use the 65nm lithography.
