NOTES:
1. Parameters are valid over specified temp. range. See Ordering Information table for applicable operating temp. and VCC supply range.
2. All voltage measurements are referenced to ground (GND). For testing, all input signals swing between 0V and 3.0V with a transition time of
20ns max. For X1/CLK, this swing is between 0.4V and 4.0V. All time measurements are referenced at input voltages of 0.8V and 2V and
output voltages of 0.8V and 2V as appropriate.
3. Typical values are at +25
°C, typical supply voltages, and typical processing parameters.
4. Test condition for outputs: CL = 150pF, except interrupt outputs. Test conditions for interrupt outputs: CL = 50pF, RL = 2.7k to VCC.
5. Timing is illustrated and referenced to the WRN and RDN inputs. The device may also be operated with CEN as the ‘strobing’ input. In this
case, all timing specifications apply referenced to the falling and rising edges of CEN. CEN and RDN (also CEN and WRN) are ORed inter-
nally. As a consequence, this signal asserted last initiates the cycle and the signal negated first terminates the cycle.
6. If CEN is used as the ‘strobing’ input, this parameter defines the minimum high time between one CEN and the next. The RDN signal must
be negated for tRWD guarantee that any status register changes are valid.
7. Consecutive write operations to the command register require at least three rising edges of the X1 clock between writes.
8. These parameters are guaranteed by design, but are not 100% tested in production.
9. Operation to 0MHz is assured by design. Minimum test frequency is 2MHz.
