Universal Flash Storage
UFS
Universal Flash Storage (UFS) is a JEDEC standard for high performance mobile storage devices suitable for next generation data storage. The UFS is also adopted by MIPI as a data transfer standard designed for mobile systems. Most UFS applications require large storage capacity for data and boot code. Applications include mobile phones, tablets, DSC, PMP, MP3, and other applications requiring mass storage, boot storage, XiP or external cards. The UFS standard is a simple, but high-performance, serial interface that efficiently moves data between a host processor and mass storage devices. USF transfers follow the SCSI model, but with a subset of SCSI commands.The Arasan UFS IP family consists of Host controller IP, Device controller IP, and MPHY.

SD Card
SD Card v.3.0 / eMMC v.4.51 IP Family
Designed for embedded applications that require high performance, small form factor, and high storage capacity, eMMC provides the support for embedded mass storage memory on embedded host systems. The eMMC protocol simplifies the access to NAND flash memories (such as MLC) to the host by hiding the functional differences among suppliers. Compliant to the latest JEDEC eMMC specifications, Arasan’s eMMC IP supports power-on-booting without the upper level software driver. The explicit sleep mode allows the host to instruct the controller to directly enter the sleep mode. The interface supports interface voltage of either 1.8V or 3.3V.

SD Card V.4.1 & UHS-II PHY
SD 4.1 Total Solution
To meet the ever increasing data transfer rate in high end applications, such as professional broadcasting transmission or advanced high resolution display, the SD 4.1 specification calls out the maximum performance of 1.56 Gbps at UHS-II full duplex mode per lane or half duplex UHS-II at 3.16 Gbps. In real applications, due to the system overhead and different SD 4.1 device controller designs, the actual measured performance can vary dramatically from system to system. With the newly introduced ADMA 3, the OS driver is now able to issue multiple read or multiple write commands at once, without having to wait for the SD controller to complete one command at a time. Once the SD host controller has collected multiple commands, it will then manage and complete them without intervention from the host software drive. Thus, the UHS-II 1.56 Gbps interface can be more effectively utilized and maximize the system throughput. This feature can be very useful when running multithreaded applications where multiple applications are constantly updating their status or swapping their contents by writing or reading small chunk of data to or from the memory card.

IP Solution
eMMC 5.1
Demand for mobile content capacity and bandwidth for video, pictures and music is ever increasing. To address this demand in the next generation of smartphones, tablets, and portable devices, the eMMC 5.1 Specification from JEDEC, improves the current HS400 speeds operating at 3.2Gbps, with "command queuing" making the data transfers highly efficient by offloading the software overhead into the controller. eMMC 5.1 further improves the reliability of operation by utilizing an "enhanced strobe" at the PHY layer. The eMMC5.1 is backward compatible with the existing eMMC 4.51 and eMMC 5.0 Devices.

MIPI SLIMbus
A typical mobile device has many low-speed/bandwidth peripherals connected to the host processor, which include microphones, speakers, sensors and many others. There is a need for a standard bus that enables multiple audio channels, peer-peer communications and lower pin count on the host processor. The MIPI alliance has defined the SLIMbus specification which provides a standard, robust, scalable, low-power, high-speed, cost-effective, two wire multipurpose interface that supports a wide range of digital audio and control solutions for mobile terminals.
