Spi Single Flash Device Length Matching Requirement; Boot Bios Destination; Serial Flash Vendors - Intel Quark SoC X1000 Design Manual

SPI Flash Design Guidelines—Intel
Table 44. LSPI0_MOSI, LSPI0_MISO, LSPI_SS_B, LSPI0_SCK (Sheet 2 of 2)
Trace Spacing(S3): Between GPIO
and other signals
Trace Segment Length
Note: * Keep La + Lb as short as possible to give the best margin on the overshoot/undershoot violation.

SPI Single Flash Device Length Matching Requirement

• LSPI_SCK & LSPI_MOSI must be length matched to within 500mils.
• LSPI_SCK & LSPI_SS_B must be length matched to within 500mils.

Boot BIOS Destination

®
Intel Quark™ SoC X1000 can only boot via the Legacy SPI interface, SPI0 and SPI1
can be used for non-volatile data.

Serial Flash Vendors

The following list of vendors manufacture serial flash devices should not be considered
as Intel Approved Devices or vendors. But these devices conform to Intel's specific
requirements. For additional details on the compatibility requirements for SPI devices
refer to the latest SoC EDS. Contact the flash vendor directly for information on
packaging and density.
