1This is a stress rating only and functional operation of the device at these or any other conditions above
those indicated in the operation sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods of time may affect reliability.
2Storage temperature is defined as the temperature of the device when V
CC=0V and VLI=0V. In this state
the contents of SRAM are not battery-backed and are undefined.
