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 maximum. For X1/CLK this swing is between 0.4V and 4.4V. All time measurements are referenced at input voltages of 0.8V and 2.0V and output voltages of 0.8V and 2.0V, as appropriate. 3. Typical values are at +25 °C, typical supply voltages, and typical processing parameters. 4. Test conditions for outputs: CL = 150pF, except interrupt outputs. Test conditions for interrupt outputs: CL = 50pF, RL = 2.7KΩ to VCC. 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 WRN) are ORed internally. The signal asserted last initiates the cycle and the signal negated first terminates the cycle. 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 be negated for tRWD to guarantee that any status register changes are valid. 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. |
