Product Description
The UltimateBlue SiW3500™ is a RF System On Chip (SoC) that combines a 2.4 GHz transceiver, baseband processor, and protocol stack software for Bluetooth® wireless technology. Due to its low power CMOS process, the SiW3500 is ideally suited for applications such as mobile phones, audio headsets, and other embedded products.

FEATUREs
• RF System on Chip (SoC) for Bluetooth wireless technology combining a 2.4 GHz transceiver, baseband processor, and protocol stack ROM.
• Bluetooth specification V1.2 qualified including mandatory and optional functions such as AFH and eSCO.
• Manufactured using standard 0.18-micron CMOS process technology.
• UART based Host Control Interface (HCI) transport layer supports standard and 3-wire modes.
• Direct conversion RF architecture improves receiver-blocking performance.
• I/O voltage supply can range from 1.62 V to 3.63 V.
• -85 dBm receiver sensitivity and +2 dBm transmitter power typical performance specifications.
• Integrated analog and digital voltage regulators simplify system design.
• 50 Ω RF I/O does not need any additional external impedance matching components.
• Flexible reference clock source options including crystal or direct input from the host platform.
• Internal temperature compensated transmitter and receiver circuits deliver consistent performance from -40° to +85°C.
• On-chip ROM software storage with patch capability.

APPLICATIONs
• Mobile phones and smart phones.
• Bluetooth audio headset.
• Bluetooth hands-free kit.
