IDT Broadens Portfolio of Flexible, Low-Power, Asynchronous Dual-Ports for High-End Handsets

Devices Offer Power Plane Technology to Reduce Design Complexity and System Power Consumption
SAN JOSE, Calif., November 17, 2008 – IDT® (Integrated Device Technology, Inc.; NASDAQ: IDTI), a leading provider of essential mixed signal semiconductor solutions that enrich the digital media experience, today introduced new series of devices in the company’s industry-leading portfolio of flexible, low-power, asynchronous dual-ports for high-end handsets. Acting as a bridge between processors, the new IDT devices allow handset designers to minimize device complexity, through increased design flexibility resulting in faster time to market. Moreover, by adding in power plane isolation functionality, the devices allow for a significant reduction in total system power consumption.
 
The IDT 70P2X5 dual-ports are designed to work with application processors and baseband processors that make use of an address-data mux (ADM) interface. The ADM interface has a lower input/output (I/O) count than other approaches, such as the standard asynchronous dual-port RAMs commonly found in high-end mobile handsets. The IDT dual-ports use 50 percent fewer processor I/O pins, freeing those pins to support desired differentiating functionality. Moreover, the IDT dual-ports also deploy eight dynamically programmable I/Os that the processor can use to control and/or monitor other devices, enabling the handset designer to add even more differentiating functionality.
 
The power plane isolation functionality uniquely inside the IDT low-power dual-ports allows handsets to achieve a true standby state and also provides the ability to power down entire processing subsystems, greatly reducing power usage and thus extended battery life. For those customers using additional logic or Complex Programmable Logic Devices (CPLD) to implement complex power management approaches, the IDT low-power dual-ports also help reduce design complexity by eliminating the need for these additional components.
 
IDT is also announcing new devices in its family of 70P2X9 dual-ports. These next-generation products are pin and backwards compatible with previous IDT devices, offering increased functionality without the need for re-design. To help in design flexibility, the devices also include selectable ADM/non-ADM operation on both ports, support for variable core and I/O supply voltages, a 256K density option and power-plane isolation functionality.
 
“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,” said Fred Zust, vice president and general manager of the IDT Communications division. “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 these dual-ports in close co-operation with leading high-end handset manufacturers and with the pre-eminent processor component provider in this application space.”
 
Pricing and Availability
All the new IDT dual-port devices are currently sampling and are offered in a 100-pin fpBGA package. They are priced at $3.00 for quantities of 10,000 units. For a full list of all IDT dual-port devices, including pricing and packaging information, visit www.IDT.com/go/Dual Port.
 
With the goal of continuously improving the digital media experience, IDT integrates its fundamental semiconductor heritage with essential innovation, developing and delivering low-power, mixed signal solutions that solve customer problems. Headquartered in San Jose, Calif., IDT has design, manufacturing and sales facilities throughout the world. IDT stock is traded on the NASDAQ Global Select Stock Market® under the symbol “IDTI.” Additional information about IDT is available at www.IDT.com.
