Preliminary

Radio 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 m 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.

Baseband Features

• Hardware based GFSK MODEM and packet processing contributes to lower system current consumption with

minimal software overhead.

• ARM7TDMI processor efficiently executes all protocol stack and application software.

• Software execution from either internal ROM or external FLASH memory. The SiW3500 features a ROM patch

mechanism that allows substituting small portions of ROM code with code either downloaded from the host or stored

in external EEPROM.

• Extensive multi function I/Os allow flexible product configurations.

• Auxiliary analog-to-digital converter (ADC) is available for applications such as battery level detection.

Standard Protocol Stack Features

• Full-featured lower layer Bluetooth protocol stack software up to the host interface (HCI).

• Bluetooth 1.2 qualified including mandatory and optional features such as AFH, extended SCO, faster connections,

and LMP improvements.

• Full Bluetooth connection capabilities with support for piconet and scatternet modes and device scanning during SCO

connection.

• Able to establish up to 3 SCO connections simultaneously.

• Supports low power connection states such as hold, sniff, and park modes with selectable sniff intervals.

• Full support of Bluetooth test modes for use during production.

• Verified HCI command level compatibility with multiple upper layer stack software.

Additional Protocol Stack Features

• Proprietary channel assessment algorithm provides fast and accurate determination of occupied channel for use in

AFH mode.

• In addition to AFH, UltimateBlue Coexistence Technology is part of the baseline protocol stack. UltimateBlue

coexistence minimizes interference to 802.11b/g products.

• The Channel Quality Driven Data Rate (CQDDR) feature optimizes data transfer in noisy or weak signal

environments.

• Full selection of upper layer protocol stack software and profiles available for license and customization.
