TABLE 1-1: DC CHARACTERISTICS
NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for an
extended period of time may affect device reliability.

Note 1: This parameter is periodically sampled and not 100% tested. Typical measurements taken at room
temperature (25°C).
2: This is the limit to which VDD can be lowered without losing RAM data. This parameter is periodically
sampled and not 100% tested.
