Recommended Pinout For 8-Pin Serial Flash Device; Recommended Pinout For 16-Pin Serial Flash Device - Intel 6 SERIES CHIPSET - DATASHEET 01-2011 Datasheet

5.24.7 SPI Flash Device Recommended Pinout
Table 5-59
Use of the recommended pin-out on an 8-pin device reduces complexities involved with
designing the serial flash device onto a motherboard and allows for support of a
common footprint usage model (refer to
Table 5-59. Recommended Pinout for 8-Pin Serial Flash Device
Pin #
Although an 8-pin device is preferred over a 16-pin device due to footprint
compatibility, the following table contains the recommended serial flash device pin-out
for a 16-pin SOIC.

5.24.8.1 Common Footprint Usage Model
In order to minimize platform motherboard redesign and to enable platform Bill of
Material (BOM) selectability, many PC System OEMs design their motherboard with a
single common footprint. This common footprint allows population of a soldered down
device or a socket that accepts a leadless device. This enables the board manufacturer
to support, using selection of the appropriate BOM, either of these solutions on the
same system without requiring any board redesign.
