In an effort to keep up with the increasing adoption of ARMv8 architecture and ARM Cortex A50 series, Arasan Chip Systems has launched versions of its mobile storage interfaces that are compatible with 64bit processors. The Arasan SD, SDIO, eMMC, ONFI and UFS Mobile Storage Host Controllers have been tailored to support 32bit and 64bit AHB or AXI bus configurations from ARM or the Open Core Protocol(OCP). Aside from new digital IP, analogue IP for these controllers has also been rolled out.

The mobile processing world is following the roadmap set by personal computing in the last decade by adopting 64bit processors. Apple's A7 processor embodied in the iPhone 5s and certain iPad models, was launched in September. Several major IC suppliers including Hauwei, LG, MediaTek, nVidia, Qualcomm and Samsung, have announced development of future mobile products based on the ARMv8.

The Arasan Mobile Storage Host Controllers now support 32bit and 64bit AHB or AXI bus configuration, which is supported in both digital IP the Arasan software stacks. Validation support will be provided with Arasan's Hardware Validation Platform for these controllers.

Standards compatible with the storage interfaces include the SD 3.0, SD 4.0, SDIO 3.0, SDIO 4.0, eMMC 4.51, eMMC 5.0, ONFI 3.2, and UFS 2.0.
