Table 1 - Schematic Overview of the ZL70102 Interconnects 3 Zarlink Semiconductor Inc. ZL70102 1.0 Product Description 1.1 Introduction Short Form Data Sheet The ZL70102 is an ultra low power RF transceiver for implantable medical applications. It operates in the Medical Implantable Communication Service1 (MICS) band at 402-405 MHz and provides a complete radio modem enabling communication to a medical device in the body. The wireless RF Telemetry link replaces the traditional inductively coupled wand and enables benefits including: • Higher data rates • Placement of the programmer further away from the body (outside the sterile area) during surgery • Remote monitoring outside the medical clinic • Body-worn applications allowing patient control and monitoring • Link to other non-implanted medical devices and sensors for more advanced applications The ZL70102 RF transceiver provides a complete radio system solution and can be used in both ends of the link, i.e., both in the Implantable Medical Device (IMD) and in the external device (base station, programmer, remote monitor, patient controller etc). ,PSODQW0HGLFDO'HYLFH 0,&6'DWD/LQN =/ %DWWHU\ +RVW& %DVH6WDWLRQ =/ *+] :DNH8S/LQN *+] :DNH8S 7UDQVPLWWHU %DVH6WDWLRQ &RQWUROOHU Figure 3 - Application Example 1.1.1 Dedicated for the Medical Implant Market The ZL70102 has been developed specifically for the medical implant market and is optimized for the requirements driven by these types of products. Robustness, quality and security have been cornerstones in the ZL70102 system definition. 1.1.2 Extreme Ultra Low Power The ZL70102 RF Transceiver is designed from the bottom-up to be a true ultra low power device. Implant medical devices normally have very limited battery resources and longevity is one of the core values of the application. The RF Telemetry link is expected to use a fraction of the battery resources from the target treatment of the IMD. Low current consumption during transmission is essential but even more important is that the radio can be kept in sleep mode for as much time as possible while maintaining responsiveness. Every block of the ZL70102 has therefore been carefully designed with ultra low power consumption in mind and advanced power management is implemented on all levels. 1. MICS is a dedicated band for non-audio implantable applications. One side of the link has to be implanted. 4 Zarlink Semiconductor Inc. ZL70102 1.1.3 Short Form Data Sheet Innovative Wake-Up System To conserve battery power it is essential to provide an ultra low power wake-up system. The ZL70102 is very versatile and supports several wake-up methods: • 2.45 GHz wake-up receiver Fully autonomous, extreme ultra low power wake-up receiver, utilizing the higher transmitted power allowed for by the 2.45 GHz ISM band. Modulation and protocol are optimized for ultra low power and robustness. • In-band (MICS) wake-up Advanced support for MICS in-band wake-up enables a simple hardware implementation (some support from the host required) • Wake-up by host Wake-up by the host controller in combination with support for the Low Duty-Cycle Mode enables scheduled communication schemes or ad-hoc wake-up initiated by the implant. 1.1.4 High Performance MAC and Autonomous Operation The ZL70102 has a simple to use packet level interface supported by a high performance MAC with automatic error correction and flow control. The host controller can concentrate on the treatment and delegate the communication to the ZL70102 transceiver. The radio can be controlled remotely through the link and could in principle operate with no host controller using the on-chip general purpose I/O’s to control a simple application. 1.1.5 Self-contained The ZL70102 Transceiver is highly integrated and self-contained. Very few external components are required to make a complete radio system: • Antenna with suitable matching network • SAW filter to suppress unwanted blockers • Crystal for the reference frequency (on-chip oscillator) • De-coupling capacitors for power supply (on-chip regulators) 1.2 Typical Applications Three typical applications are presented below. The chapter “Typical Application Examples” on page 12 will provide schematics and more details. These three typical applications are intended as a starting point for the target application. 1.2.1 Extreme Ultra Low Power Devices This application area has been dominated by Cardiac Rhythm Management products like pacemakers and Implantable Cardioverter Defibrillators (ICD) where low power and device longevity were very important characteristics of the device market long before RF Telemetry was introduced. This means that the industry is willing to take extra efforts to save power even if this results in a moderate increase in complexity. There are other new applications that also fall into this category. To address this need the ZL70102 is equipped with an extreme ultra low power 2.45 GHz Wake-Up system that provides by far the lowest power consumption. The 2.45 GHz wake-up system is also autonomous and fully integrated when the ZL70102 is used in an implant. 5 Zarlink Semiconductor Inc. ZL70102 1.2.2 Short Form Data Sheet Ultra Low Power Devices Many neurostimulators, drug delivery systems, sensors and diagnostic applications are operated in a mode allowing higher power consumption since the core function itself consumes more power requiring use of larger or re-chargeable batteries. This allows alternative wake-up solutions to be used like the in-band MICS wake-up that simplifies the hardware design (the matching network and antenna only uses the 400 MHz MICS band). 1.2.3 External Devices • Programming base stations • Home/remote monitoring devices • Handheld, mobile and belt-worn applications This is the other side of the MICS link with a higher allowed power budget in comparison with the implanted device. The external device, acting as a base station, also has to fulfill other requirements in the MICS standard like Clear Channel Assessment (CCA) and it is required to transmit the 2.45 GHz wake-up packet if the 2.45 GHz wake-up option is used. 6 Zarlink Semiconductor Inc. ZL70102 2.0 Short Form Data Sheet Ordering and Package Overview Implant Grade Pb Free The ZL70102 RF Transceiver is available in several package options.

External Devices ZL70102 3.0 Functional Description 3.1 General Short Form Data Sheet The ZL70102 is an ultra low power, high bandwidth RF transceiver for medical implantable applications. It operates in the Medical Implantable Communication Service (MICS) band at 402-405 MHz. It uses a forward error correction scheme together with CRC error detection to achieve an extremely reliable link. For standard data-blocks a maximum Bit Error Rate (BER) of less than 1.5x10-10 is provided assuming a raw radio channel quality of 10-3 BER. An even higher quality of 2x10-14 BER is available for housekeeping messages. 3.1.1 Basic Modes The ZL70102 transceiver is designed for operation in both an implant and base station application. These systems have different requirements especially with regard to power consumption. Therefore, the ZL70102 transceiver has defined two basic modes (configured by the IBS pin): • IMD Mode The device is asleep waiting for a wake-up event • Base-Idle Mode The device is powered up and idle When configured in IMD Mode, the transceiver is usually asleep and in an ultra low current state. The IMD may be woken up to initiate communications by either receipt of a specially coded 2.45 GHz wake-up message or directly by the IMD processor via the WU_EN pin. This flexibility leads to the following options for waking up an IMD transceiver for communication. • IMD transceiver woken up by specially coded 2.45 GHz wakeup message using an ultra low power sniffing method. • IMD transceiver woken up to sniff 400 MHz link. The ZL70102 supports such a mode of operation although the 2.45 GHz wakeup system has lower power consumption. • IMD transceiver woken to send an emergency message in which case no clear channel assessment by the Basestation is required. • IMD transceiver woken to send a low duty cycle mode message in which case no clear channel assessment by the Basestation is required1. • IMD transceiver woken up by the IMD host processor based on some alternative mechanism. 1. The allowed maximum radiated output power is reduced in this mode. 8 Zarlink Semiconductor Inc.
