In wait, doze, and stop modes, clocks to the SRAM are disabled. No
recovery time is required when exiting any low-power mode.

falls below the minimum required voltage, the SRAM contents may be
corrupted. The SRAM automatically switches to standby operation with
no loss of data when the voltage on V
In standby mode, the SRAM does not respond to any bus cycles.
Unexpected operation may occur if the central processor unit (CPU)
requests data from the SRAM in standby mode. If standby operation is
not needed, then the V

where:
I is the difference between the transition current requirement and the
maximum power supply current,
t is the duration of the V
threshold, and
V is the difference between the minimum available supply voltage and
the required minimum V
