3XX Datasheet, PDF (27/82 Pages) Intel Corporation – Celeron D Processor

Electrical Specifications
11. These specifications are different depending on whether the platform is forward compatible to the Celeron D pro-
cessor or if it is optimized for the Celeron D processor. A compatible platform is one that is designed for a previous
generation processor but has some level of compatibility with the Celeron D processor. An optimized platform is one
designed specifically for the Celeron D processor; however, it may have some level of compatibility with previous
generation processors.

NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All outputs are open drain.
3. V_HYS represents the amount of hysteresis, nominally centered about 0.5 * V_CC for all TAP inputs.
4. The V_CC referred to in these specifications refers to instantaneous V_CC.
5. The maximum output current is based on maximum current handling capability of the buffer and is not specified into
the test load.
6. Leakage to V_SS with pin held at V_CC.
7. Leakage to V_CC with Pin held at 300 mV.
8. These values work for compatible and optimized platforms. A compatible platform is one that is designed for a pre-
vious generation processor but has some level of compatibility with the Celeron D processor. An optimized platform
is one designed specifically for the Celeron D processor; however, it may have some level of compatibility with pre-
vious generation processors.
