NOTES:
1. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4 V and 2.4 V with a transition time of
20 ns maximum. For X1/CLK this swing is between 0.4 V and 4.4 V. All time measurements are referenced at input voltages of VIL and VIH,
as appropriate.
2. Typical values are at +25
°C, typical supply voltages, and typical processing parameters.
3. Test condition for interrupt and I/O outputs: CL = 50 pF, RL = 2.7 k to VCC. Test conditions for rest of outputs: CL = 150 pF.
4. Timing is illustrated and referenced to the WRN and RDN inputs. The device may also be operated with CEN as the ‘strobing’ input. CEN
and RDN (also CEN and WRN) are ANDed internally. As a consequence, the signal asserted last initiates the cycle and the signal negated
first terminates the cycle.
5. The minimum value is not tested, but is guaranteed by design. For tCLK minimum test rate is 2.0 MHz.
