USB/IrDA Bridge Controller
DESCRIPTION
SigmaTel STIr4115 cost, power, USB/IrDA Bridge Controller integrated circuit enabling IrDA wireless data communications through standard port. STIr4115 directly interfaces wide family IrDA transceiver module architectures contains controller, IrDA controller, interface logic, memory buffer full IrDA data transfer rates. STIr4115 designed serve markets that support communications portable digital devices that have need capability higher speed more expensive data transfer rates. Such products include cell phones personal data assistants that because power cost requirements themselves support higher data rates. These types applications have historically been served serial (RS-232) interface products, STIr4115 provides cost effective legacy-free solution. STIr4115 bundled with Windows 98SE/ME/2000/XP® NDIS/USB driver enabling implementation cost effective USB/IrDA Adapter solution wireless data communications.
FEATURES Provides cost-effective migration from RS-232 connectivity legacy-free support. Fully compatible with cost power transceivers Low-power CMOS design Supports IrDA data rates from Kbps Kbps Obtains power from port Full compliance IrDA specifications Kbyte FIFO buffer memory Uses single crystal Windows 98/98SE/ME/2000/XP® NDIS/USB driver Low-profile 28-Pin SSOP package
