3.7. Serial ATA Interface
The EDM-IMX6 incorporates a single SATA-II port implemented with the NXP i.MX6 integrated SATA
controller and PHY.
The interface supports the following main features:
•
The SATA block fully complies with AHCI specification version 1.10 and partially complies with
AHCI specification version 1.3 (FIS-based switching is currently not supported).
•
SATA 1.5 Gb/s and SATA 3.0 Gb/s speed.
•
Power management features including automatic partial-to-slumber transition.
•
eSATA (external analog logic also needs to support eSATA).
•
Hardware-assisted Native Command Queuing (NCQ) for up to 32 entries.
For additional details, please refer to
the “Serial Advanced Technology Attachment Controller (SATA)”
chapter of the “i.MX6 Reference Manual”.
