Items [1] Possible increased power down current Part Numbers Fix Status All Will be corrected in the next silicon revision. The errata is forecast to be corrected for all devices dated October 2007 and later. 1. Possible increased power down current • PROBLEM DEFINITION When the device is in the power down state, an unbonded pad on the die is allowed to float. Because of this, power down current may exceed the data sheet limit. While high current draw is theoretically possible any time during power down, it has only been observed as a transient occurrence shortly after the device enters power down. Steady-state current has always been observed to be within data sheet limits. • PARAMETERS AFFECTED Parameter Temperature Range Data Sheet Maximum Actual Maximum IDD (PD Mode) Commercial 12 µA 3.5 mA Industrial 25 µA 3.5 mA • TRIGGER CONDITION(S) None.

The errata is forecast to be corrected for all devices dated October 2007 and later.
