Fix Status
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 ob-
served to be within data sheet limits.

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.
