1. Parameters are valid over specified temperature range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4V and 3.0V with a transition time of 5ns
3. Typical values are at +25 C, typical supply voltages, and typical processing parameters.
4. Test conditions for outputs: C
5. Timing is illustrated and referenced to the WRN and RDN inputs. Also, CEN may be the ‘strobing’ input. CEN and RDN (also CEN and
6. If CEN is used as the ‘strobing’ input, the parameter defines the minimum High times between one CEN and the next. The RDN signal must
7. Minimum frequencies are not tested but are guaranteed by design. Crystal frequencies 2 to 4 MHz.
8. Clocks for 1X mode should be symmetrical.
