NOTES:
1. Parameters are valid over specified temperature range. See ordering information table for applicable temperature range and operating
supply range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4V and 2.4V with a transition time of 20ns
maximum. For X1/CLK this swing is between 0.4V and 4.4V. All time measurements are referenced at input voltages of V
IL
and V
IH
, as
appropriate.
3. Typical values are at +25
°
C, typical supply voltages, and typical processing parameters.
4. Test condition for interrupt and MPP outputs: C
= 50pF, R
= 2.7k
to V
. Test conditions for rest of outputs: C
= 150pF.
5. 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.
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 t
RWD
guarantee that any status register changes are valid.
7. Consecutive write operations to the command register require at least three edges of the X1 clock between writes.
8. This value is not tested, but is guaranteed by design.
9. See UART applications note for power down currents less than 5
μ
A.
10.Operation to 0MHz is assured by design. Minimum test frequency is 2MHz.
11. Address is latched on leading edge of read or write cycle.
