CS1 (Chip Select)
VIH and VIL of CS1 have 3 functions:
1. To accomplish the interface with a microcomputer in 5V operation.
2. To inhibit the control bus, data bus and address bus and to reduce input gate pass current
in the stand-by mode.
3. To protect internal data when the mode is moved to and from stand-by mode.
To realize the above functions:
1. More than 4/5 VDD should be applied to this IC for the interface with a microcomputer in
5V operation.
2. In moving to the stand-by mode, 1/5 VDD should be applied so that all data buses should
be disabled. In the stand-by mode, approx. 0V should be applied.
3. To and from the stand-by mode, obey the following Timing chart.
]
The stand-by mode means the power supply voltages from 4V to 2V up to the minimum
value (2V) of the operating power supply voltage and the interface with the IC external is not
guaranteed while the clock time works.

The CS0 of this IC does not
generate "H" or WR during
this duration.
The interface with this IC
is available after this.
As a matter of fact, regard this matter as the
data holding in the stand-by of STATIC RAM.
