MOTOROLA FAST SRAM
APPLICATION INFORMATION
STOP CLOCK OPERATION
In the stop clock mode of operation, the SRAM will hold all
state and data values even though the clock is not running
(full static operation). The SRAM design allows the clock to
start with ADSP and ADSC, and stops the clock after the last
write data is latched, or the last read data is driven out.
When starting and stopping the clock, the AC clock timing
and parametrics must be strictly maintained. For example,
clock pulse width and edge rates must be guaranteed when
starting and stopping the clocks.
To achieve the lowest power operation for all three stop
clock modes, stop read, stop write, and stop deselect:
Force the clock to a low state.
Force the control signals to an inactive state (this guaran-
tees any potential source of noise on the clock input will not
start an unplanned on activity).
Force the address inputs to a low state (VIL), preferably
< 0.2 V.

NOTE: For lowest possible power consumption during stop clock, the addresses should be driven to a low state (VIL).
Best results are obtained if VIL < 0.2 V.
