E7160-0-102A57-AG Introduction

Ezairo® 7160 SL is an open−programmable DSP−based hybridspecifically designed for wireless, high−performance hearing aids.The Ezairo 7160 SL hybrid is based on the Ezairo 7100System−on−Chip (SoC) and includes RSL10− the industry’s lowestpower Bluetooth® 5 radio SoC, EA2M a 2 Mb EEPROM, and allnecessary passive components for interfacing with transducers.Ezairo 7100 features a high precision quad−core architecture thatdelivers 375 MIPS without sacrificing power consumption. Thedual−Harvard CFX Digital Signal Processor (DSP) core is optimizedto run advanced hearing aid algorithms, while the HEAR ConfigurableAccelerator engine performs many different types of audio processing.Complementing the DSP core, the Arm® Cortex®−M3 processorsupports wireless protocols and combines an open−programmablecontroller with hardware accelerators for audio coding and errorcorrection support. Ezairo 7100 also includes a programmable FilterEngine that enables time domain filtering and supports anultra−low−delay audio path.Offering the industry’s lowest power consumption in deep sleep andpeak receiving, RSL10 is a highly flexible multi−protocol 2.4 GHzradio specifically designed for use in high−performance wearable andmedical applications. With its Arm Cortex−M3 processor andLPDSP32 DSP core, RSL10 supports Bluetooth low energytechnology and 2.4 GHz proprietary protocols.
