IS3 Serial ATA III

This course covers SATA III

formateur
Objectives
  • This course explains how SATA maintains compatibility with IDE software management .
  • The hardware layer is detailed, including the analog part and Out-Of-Band signals operation.
  • The FIS is analyzed in order to understand the dialog between Host Controller and mass storage device.
  • The course clarifies the programming interface specified by the Advanced Host Controller Interface .
  • The Gen3 physical layer specification and testing requirements are particularly detailed.
  • The course describes the low power modes.

  • It has been delivered several times to companies developing SoCs for wireless / consumer market.
Timing diagrams are taken from a PC implementing a SATA interface thanks to the Lecroy analyser.
A more detailed course description is available on request at training@ac6-training.com
