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.
Arasan’s general purpose I/O PADs are multipurpose PADs that can be programmed to operate in different modes: 1) Output with predetermined source/sink impedance, 2) Open drain, 3) Input, 4) Tristate and 5) Weak pull up or pull down. The I/O PADs are specially designed to seamlessly integrate with Arasan’s eMMC 5.1 and eMMC 5.0 host controller IP. Arasan introduced the industry’s first HS400PHY in 2013 on multiple nodes and since then the engineering team has been working diligently to keep up with the latest versions.
