Marvell Introduces 90 nm WLAN Single Chip Solution
Marvell introduced an ultra-low-power 90 nm Wireless LAN single chip solution. Targeted at a wide variety of consumer devices, including 3G+ and broadband handsets, it integrates an ARM compliant CPU, high speed serial host interfaces including SDIO and SPI to ensure interoperability with a variety of host systems, and advanced 802.11 a/b/g RF transceiver with full cellular coexistence.
Marvell said its new 88W8686 device, which represents its third generation technology, raises the bar on WLAN performance by drawing less than 400 Mw on a total system footprint of less than 50 mm2. The company claims its solution in a dual mode handset would result in connected standby times in excess of 250 hours and talk time in excess of 10 hours, versus current solutions which offer on average 70 and 4 hours respectively. Additionally, the device supports advanced layer 3/4 packet processing (TCP/IP) along with enhancements for UMA and IMS 3G services.
"Our vision of the smallest and lowest-power silicon solution drove our 90 nm process development. The Marvell 88W8686 gives our customers the ability to enhance battery life by at least 100%," said Dr. Paramesh Gopi, General Manager of the Embedded and Emerging Business Unit, Communications and Consumer Business Group at Marvell.
