• Manufacturer Part Number: sc3200
• Description: Geode-tm Sc3200 Processor
• Manufacturer: Advanced Micro Devices

Electrical Specifications
9.3.5
The SC3200 is compliant with PCI Bus Rev. 2.1 specifica-
tions. Relevant information from the PCI Bus specifications
is provided below.
Note 1. Refer to the V/I curves in Figure 9-13. This specification does not apply to PCICLK0, PCICLK1, and PCIRST#
Note 2. Maximum current requirements are met when drivers pull beyond the first step voltage. Equations which define
Note 3. Rise slew rate does not apply to open-drain outputs. This parameter is interpreted as the cumulative edge rate
