The Arasan PAD set fully supports the eMMC 5.0 HS400 specification at 3.3v output. At 200 MHz, the required clock speed of HS400, a DLL is required to ensure accurate data transfer. The HS400 mode uses a 200 MHz clock and DDR signaling to achieve a maximum bandwidth of 400 MB/s. The Arasan eMMC

"Arasan is the market leader in analog and digital IP for mobile storage. By making these ready-to-use PADs and PHY available, eMMC 5.0 implementation is simplified, especially for teams without analog layout skills," said
Last month JEDEC published the latest version of the eMMC v5.0 standard that defines new functionalities and enhancements for embedded mass-storage flash memory widely used in consumer electronics, including tablets, smartphones, GPS systems, eReaders and other mobile computing devices. The previous version of the standard that supported speeds up to 200 Mega Transfers per Second permitted a digital implementation. eMMC v5.0 doubles the bandwidth to 400MB/s, but requires analog components (I/O PADs and PHY). At this performance level, interface timing tuning, which has been a feature of eMMC, must be done in an analog PHY instead of using a simple tapped delay line.
eMMC is an embedded non-volatile memory system, consisting of both flash memory and a flash memory controller that simplifies the application interface design and frees the host processor from low-level flash memory management. This benefits product developers by reducing time-to-market as well as facilitating support for future flash device offerings. eMMC, offered in small BGA package sizes featuring low power consumption, is the dominant, low-cost memory solution for mobile and other space-constrained products.
Arasanís 28nm eMMC 5.0 PHY consists of three components
First, Arasanís 28nm 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)
The PAD is designed using TSMCís 28HPM process technology. With such wide performance/leakage coverage, the 28HPM process is ideal for many applications from networking, tablets, to mobile consumer products.
Second, the Arasan DLL works in conjunction with a 32 tap delay line and multiplexing logic to align the placement of clock edges. It utilizes the 28nmHPM process and is intended for core voltage of 0.9V and I/O voltage of 3.3V.
Third, the Arasan solution provides a calibration I/O PAD that automatically goes to a low power state after resistor value selection. This architecture minimizes power and area in a design.
eMMC is the dominant flash interface in cell phones and tablets today. Shipments of eMMC solutions this year are forecasted to reach 700 million according to an IHS iSuppli Mobile & Embedded Memory Market Tracker report in segments such as tablets, e-book readers and portable GPS navigation devices. The eMMC v5.0 standard is projected to ramp quickly in mainstream devices. By 2015, mobile memory revenue will peak at
