Consumer and Portable Medical DevicesLow-Power RF Products, ZigBee15➔ZigBee for Medical ApplicationsThe world is going wireless and medical applications are no exception.More and more medical devices, especially patient monitoring, canbenefit from wireless ZigBee technology. With the use of wirelesssensors, the patients can move around in the hospital, or even intheir homes, and the sensors will still monitor and send critical healthdata to the hospital or doctor. Being independent of a patient’s exactgeographical location has a positive impact on both the patient andthe hospital.The ZigBee standard enables companies to have a simple, reliable,low-cost and low-power standard-based wireless platform for theirapplication development. TI’s low-power RF portfolio of highperformanceRF ICs offers robust and cost-effectivesolutions for a variety of medical devices.RF-ICs Compliant with IEEE 802.15.4/ZigBeeSpecifications• CC2420: Industry-leading RF transceiver provides maximum flexibilityas it can be combined with microcontroller• CC2430: True System-on-Chip (SoC) with integrated microcontroller• CC2431: SoC with integrated location capabilities• Hardware development kits• High-performance and robust reference designs• Free Z-Stack ZigBee 2006 compliant stack• Free IEEE 802.15.4 MAC softwareZigBee Software Development Suite• Z-Stack: Industry-leading ZigBee protocol stack from TI• Z-Stack: Protocol stack extensions• Z-Tool (debug tool)DigitalAnalogMixedRESET_NXOSC_Q2XOSC_Q1P2_4P2_3P2_2P2_1P2_0P1_7P1_6P1_5P1_4P1_3P1_2P1_1P1_0P0_7P0_6P0_5P0_4P0_3P0_2P0_1P0_0I/O ControllerCC2430RESET32MHzCrystal OSC32.768kHzCrystal OSCDebugInterfaceDMA∆Σ ADCAudio/DC8 ChannelsUSART1USART2Timer 1 (16-Bit)Timer 3 (8-Bit)Timer 4 (8-Bit)WatchdogTimerHigh SpeedRC-OSC3:2kHz RC-OSCClock Mux &Calibration8051 CPUCoreAESEncryptionandDecryptionTimer 2IEEE 802.15.4 MAC TimerCC2430 functional block diagram.On-Chip VoltageRegulatorPower On ResetBrown OutDemodulatorSleep TimerSleep Mode ControllerMemoryArbitratorIRQControlReceiveChainRadio RegistersCSMA/CS StrobeProcessorASC32/64/128kBFlash8kBRAMFlashWriteRadio Data InterfaceRF_PFrequencySynthesizerRF_NV DD (2.0 - 3.6V)DCOUPLModulatorTransmitChaniFIFO and Frame ControlApplications• Patient monitoring• Hospital equipment trackingFor more information visit: www.ti.com/zigbeeTexas Instruments 2Q 2007Medical Applications Guide
