[1] Possible increased power down current
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 IDD (PD Mode) Temperature Range Commercial Industrial Data Sheet Maximum 12 A 25 A Actual Maximum 3.5 mA 3.5 mA
* TRIGGER CONDITION(S) None.

Errata Document
CY2305C
* SCOPE OF IMPACT Possible increased power consumption when in the power down state (that is, when the reference clock is static). * WORKAROUND None. * FIX STATUS The silicon will be revised to correct this errata. The errata is forecast to be corrected for all devices dated October 2007 and later.
