Wireless for Implantable Medical DevicesThe ZL70102 is not recommended for new designs. Please see our new Implantable Medical Transceivers.The ultra-low-power ZL70102 RF transceiver chip supports a very high data rate RF link for medical implantable communication applications. The chip’s unique design allows patient health and device performance data to be quickly transmitted, with little impact to the useful battery life of the implanted device. The ZL70102 is designed for use both in implanted medical devices and in base stations and operates in the 402-MHz – 405-MHz MICS band (or Medical Implantable Communications Service band, which is a subset of the designated MedRadio frequency band). Merging Microsemi’s ultra-low-power and RF expertise, the ZL70102 delivers key performance and integration benefits. The chip is very flexible and supports several low-power wake-up options. Extreme ultra-low-power operation is achieved using the 2.45-GHz ISM-band wake-up receiver option. The high level of integration includes a MAC (media access controller) providing coding and decoding of RF messages, forward error correction, and CRC (cyclical redundancy check) error detection to achieve an extremely reliable link. A standard serial peripheral interface (SPI) provides for easy access by the application.Key FeaturesMeets performance, power, and size requirements for implanted communication systemsOperates in the 402-MHz – 405-MHz (10 MICS-band channels) and 433-MHz – 434-MHz (2 ISM-band channels) frequency bandsHigh data rates (800/400/200 kbit/s raw data rate) allow for short-duty-cycle, power-efficient bidirectional transmission of patient and device dataUltralow power consumption of typically less than 5 mA average TX/RX extends implanted device battery operating lifeHigh level of integration System-on-Chip (SoC) design with integrated high-performance MAC with automatic error handling and flow controlVery few external components (three components plus antenna matching)Ultra-low-power RF wake-up receiver (typical 290 nA at 1-second strobe period)Compliant with MICS/MedRadio, FCC, ETSI and IEC standardsThe ZL70102 MICS-band RF transceiver IC is supported by a full featured Application Development Kit ZLE70102BADA.ZL70102-Based RF ModulesZL70120MNGZL70321MNJ
