Integrated Device Technology (IDT) introduced the Synchronous Mobile Multimedia Interconnect (M2I) optimized for mobile handsets and PDA. Mobile Multimedia Interconnect chip is six times faster with ninety percent less battery drain compared to previous generation interfaces. The interface of the Mobile Multimedia Interconnect enables the processor to support additional functionality such as WiFi, GPS and Bluetooth.

Thomas Brenner, IDT Flow Control Management Division, said:

The high-end handset consumer demands high-speed downloads, as well as top-quality playback. However, this speed and quality must be delivered without draining the battery…

We identified the interface between the baseband and application processors as a major performance bottleneck and battery drain. It was clear that a new interconnect architecture was needed to solve this problem, so we designed the Mobile Multimedia Interconnect in close co-operation with leading high-end handset manufacturers and with the pre-eminent processor component provider in this application space…

Feature of Mobile Multimedia Interconnect (M2I)

1.8 V core voltage
15 mA and 2 mA typical operating and standby currents

800 Mbps through-put per port

Full counters to support burst operations

Mobile Multimedia Interconnect (M2I) Smartphone Application

Mobile Multimedia Interconnect chip is designed to work with processors that make use of an address-data multiplexing interface, which has lower I/O count and higher bandwidth than other approaches commonly found in mobile handsets. The Mobile Multimedia Interconnect chip uses fifty percent fewer processor I/O pins. The free pins is used to support differentiating functionality. Mobile Multimedia Interconnect chip has eight dynamically programmable I/Os that can be use to control and monitor other devices.

Benefit of Mobile Multimedia Interconnect (M2I)

Reduces battery drain by 90% during media transfers

Enables performance 6X greater than legacy dual-ports for quicker media transfers

Enables more efficient data transfers by reducing the cycles required by approximately 50%

Allows software flags to be passed between processing subsystems

Facilitates a modular design approach by maintaining compatibility to new and legacy processors

Frees up GPIO pins which can be used for greater product differentiation

Limits board space consumption

The Mobile Multimedia Interconnect architecture achieves its high-performance and low-battery drain using a synchronous clocking scheme that enables the use of an internal counter that eliminates the necessity for multiple addressing. The cycles run three times faster, thus providing an overall performance increase of 6X. All this is accomplished with ninety percent less battery drain.

Mobile Multimedia Interconnect chip is in sampling now. Mass production price is $3.00 (10K lot qty). The chip is shipped in BYG100 fpBGA (6mm x 6mm x 1mm) package.
