Silicon Wave and RF Micro Devices have introduced the SiW3500 UltimateBlue IC, a complete single-chip CMOS Bluetooth solution that has features found in Bluetooth Specification Version 1.2, including faster connecting times, adaptive frequency hopping for improved coexistence of Bluetooth with other 2.4 GHz devices and extended SCO for improved voice transmissions.
The circuit combines a direct conversion radio modem with an ARM7TDMI processor core, Bluetooth baseband logic, and complete protocol software in ROM.
The chip is a complete platform that can execute additional upper layer protocol stack and application software functions, including additional complex audio processing algorithms such as noise cancellation without a separate DSP.
