This device is lead-free. That is, lead has not been intentionally added, but lead may still exist as an impurity at <1000 ppm. The Material Declaration Data Sheet, which includes lead impurity levels and the concentration of other Restriction on Hazardous Substances (RoHS)-banned materials, is available at: ftp://download.intel.com/design/packtech/material content IC Package.pdf pagemode=bookmarks In addition, this device has been tested and conforms to the same parametric specifications as previous versions of the device.

Updated Section 4, Voltage, Temperature, and Timing Specifications, for the C-0 Mar 2004 3.0 stepping. Corrected EEMODE signal description. Oct 2004 3.1 Updated signal names to match design guide and reference schematics. Added lead free information. Added information about migrating from a 2-layer 0.36 mm wide-trace substrate to a 2-layer 0.32 mm wide-trace substrate. Refer to the section on Package and Pinout Information. Nov 2004 3.2 Added statement that no changes to existing soldering processes are needed for the 2-layer 0.32 mm wide-trace substrate change in the section describing Package Information. Corrected pinout discrepancies between sections Signal Descriptions and Package and Pinout Information. Added new maximum values for DC supply voltages on 1.2 V and 1.8 V pins. See Jan 2005 3.3 Table 2, Recommended Operating Conditions and Table 6, DC Characteristics. Feb 2005 3.4 Updated Visual Pin Assignment diagram for pinouts F9, F10, E14, F14, and H14. Removed all references to CLK RUN signal. Apr 2005 3.5 Corrected the FLSH SO/LAN DISABLE signal definition. If Flash functionality is not used then an external pull-down resistor is required. July 2005 3.6 Added pin C8 description to Table 29 and Table 31. Aug 2005 3.7 Corrected 25 MHz Clock Input Requirements in Table 13. Corrected the FLSH SO/LAN DISABLE signal definition. If Flash functionality is June 2006 3.8 not used then an external pull-up resistor is required. June 2006 3.9 Updated Table 13 25 MHz Clock Input Requirements. Updated Table 40 descriptions for pins A10, B10, and C9. Aug 2006 4.0 Updated pinout descriptions from Tables 25 - 42 to match Figure 13. Removed note b from Table 2 and note a from Tables 3 and 4. Moved the note Sept 2006 4.1 following Table 5 before Table 3 3.3V Supply Voltage Ramp Added new Intel logo, updated Product Features, and added new document Aug 2007 4.2 ordering information to copyright page.
