Arasan: 64-Bit Compatible Interface IP for Mobile Storage

Arasan Chip Systems, Inc., provider of IP solutions for mobile applications, announced the availability of compatible mobile storage interfaces for 64-bit processors, using system host interfaces AHB, AXI or OCP.

Compatible standards include: 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.

The mobile processing world is following the roadmap set by personal computing in the last decade by adopting 64-bit processors. In the last few months, many of the leading mobile application processor suppliers have announced ARMv8 architecture licenses and/or ARM Cortex A50 series licenses. Apple’s A7 processor embodied in the iPhone 5s and certain iPad models, was launched in September.  Several 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 – SD, SDIO, eMMC, ONFI and UFS – now support 32-bit and 64-bit AHB or AXI bus from ARM or the OCP (Open Core Protocol). Bus configuration is supported in both digital IP the Arasan software stacks.  Validation support will be provided with Arasan’s HVP (Hardware Validation Platform) for these controllers.

“Arasan is the market leader in analog and digital IP for mobile storage. Providing compatibility for the next generation of application processor demonstrates Arasan’s continued leadership role for interface standards from JEDEC, SD Association and ONFI,” said Andrew Haines, VP marketing.

Digital IP for Arasan’s SD/eMMC, ONFI, and UFS host controllers is available. Analog IP (PHY) including optimized Pads, for these controllers is also available.
