LSI Logic Delivers Ultra-Sleek LSI403US DSP to Enable Growing Voice Over WLAN Handheld Market

MILPITAS, Calif., Aug. 2, 2005 -- The DSP Product Division of LSI Logic Corporation today announced the LSI403US digital signal processor (DSP) in a 7 mm x 7 mm chip package. The latest addition to the ZSP® family of processor solutions, the LSI403US is a low- cost, low-power voice processor in an ultra-thin package that delivers the perfect mix of high performance and small footprint necessary in Voice over WiFi (VoWiFi) applications such as cell phones, PDAs and other handheld devices.

"The wireless mobile market is growing rapidly with an increasing number of handhelds at smaller form factors being brought to market," said Will Strauss, president of analyst firm Forward Concepts. "With the LSI403US, LSI Logic is tapping into the fast-growing VoWiFi market that is emerging in WLAN- specific handsets as well as in PDAs and cell phones. We forecast the collective VoWiFi chip market to grow from a low base this year to 142 million units shipping in 2009."

Based upon the award-winning, ultra-low-cost, low-power LSI403LC processor, the LSI403US features a sleek 144 LBGA (7 mm x 7 mm) package, dual TDM ports for audio ADC/DACs, interfaces for additional wireless devices, such as WLAN and Bluetooth, and is perfect for VoWiFi dual-mode mobile phones. The Z.Voice software library* of industry standard VoIP algorithms and the ultra- thin packaging allows system designers to benefit immediately from the LSI403US. "LSI Logic is continuing to demonstrate leadership by providing innovative DSP solutions for multimedia, voice and wireless applications requiring peak performance," said Ramesh Bhimarao, voice product line manager, DSP Product Division, LSI Logic. "With low power, high performance and a sleek package, the LSI403US enables customers to create small form factor end products that meet the growing demand for VoWiFi capability."

The LSI403US is immediately available and is priced below $4.00 in 100K volume shipments.
