Bluetooth Intelligent Serial Module Ivan Mitic CODICO October 2003 Slide 1

Serial Module Approved as an END PRODUCT No customer approvals required (Murata, Alps etc need approval) 5 I/O Lines 2 ADC Channels Serial Profile – Industrial Automation DUN Profile – Phone Access Headset Profile – Voice Applications 2

Bluetooth Overview Wireless Cable Replacement Technology Range 10 metres – 200 metres Output Power 1 m. W – 100 m. W 2. 4 GHz, SSFH, 1, 600 hops per second Max data rate 721 kbps. 3 x Voice channels Low power consumption for handheld applications 3

Simple Software Integration All modem control signals available e. g DTR, DSR. DCD, RI, RTS Configurable baud-rates up to 921, 600 bps Connections can be dropped via ^^^ escape sequence or when DSR is de-asserted. Connections indicated by assertion of DCD In coming connections indicated via RI line Can be member of a piconet when connect device is terminated All I/O lines accessible via S registers using the AT protocol Prototypes work in hours rather than months 4

Commercial Advantages Based on Technology Leading TDK design Optimised RF design gives ~ 200 m range Virtual Machine eliminates extra flash and processor, so 50% of cost of rival products Excellent RF immunity from TDK Antenna design. Full Software and Firmware Support available Guaranteed Bluetooth Interoperability Fully Pre-Approved – no Bluetooth or RF knowledge required from integrator. TDK is responsible for all of the RF and Bluetooth. Wireless becomes as simple as adding a connector 5

TDK Adaptor Advantages #1 Feature Pre-Qualified TDK Others YES ? Benefit Saves up to $70 k of approval costs Antenna Ceramic Printed / None Improved range. Better discrimination as antenna is an extra band pass filter. AT Command set YES Some Virtual Machine YES NO Makes programming much easier No external microprocessor – lower cost Development System Range Voice Support YES NO Typ > 100 m < 50 m YES Rare Faster time to market Greater Range Audio / Voice applications 6

TDK Adaptor Advantages #2 Feature TDK Others Benefit Temp Range -25 > +100 -20 > +50 Ideal for automotive and industrial Firmware License YES NO Route to low cost volume manufacture for OEMs Interference Rejection Excellent Average TDK Antenna technology gives superb rejection – ideal for noisy environments. Low Power Good Average TDK supports ultra low power modes for low speed <9600 Baud, opening opportunity for serial port powered devices. High Data Rates > 200 k Typ < 100 k Real rates maintained at FULL range. 7
