What is MIPI #1 Specification?

I got several inquiries about adoption rate of physical layers across the mobile and adjacent industries after posting the video showing D-PHY v1.2 silicon on 16nm I realize that it’s debatable if it’s fair to compare one spec vs the other. However, I would like to note that de-facto standard has a lot of weight and it is what sets it apart compared to other potential specifications which only a few vendors select. Once a certain standard is well adopted across the industry, it establishes an entrenched position and cannot be replaced instantly. Any potential replacement standard need to take into consideration backwards compatibility to ensure vendor’s investment in the de-facto standard continues to bear fruits. It requires a phased approach towards replacing a successful standard and it’ll only be possible if the replacement standard has proven benefits compared to the de-facto standard and that the transition period is not long and not painful.

UFS, UniPro and You

JEDEC UFS (Universal Flash Storage) v1.1 is a standard promoted by JEDEC JC64.1 aiming to replace eMMC for scalable and high performance non-volatile memory interface in mobile and consumer electronics. The same JEDEC JC64.1 is the group that develops eMMC meaning that they see the transition from eMMC to UFS and are prepared to that. It’s fair to assume that UFS will be used in high end mobile applications first like high end smartphones, tablets and Ultrabooks and compete with eMMC on some of the lower end applications. Long term and assuming high volume manufacturing reduces UFS device costs we will see UFS replacing eMMC but there is a long way to go until we reach that time.
