Onsemi Ezairo E7160SL Audio Processor(IC)

Ezairo® 7160 SL is an open−programmable DSP−based hybrid specifically designed for wireless, high−performance hearing aids. The Ezairo 7160 SL hybrid is based on the Ezairo 7100 System−on−Chip (SoC) and includes RSL10− the industry’s lowest power Bluetooth® 5 radio SoC, EA2M a 2 Mb EEPROM, and all necessary passive components for interfacing with transducers.

Ezairo 7100 features a high precision quad−core architecture that delivers 375 MIPS without sacrificing power consumption. The dual−Harvard CFX Digital Signal Processor (DSP) core is optimized to run advanced hearing aid algorithms, while the HEAR Configurable Accelerator engine performs many different types of audio processing.

Complementing the DSP core, the Arm® Cortex®−M3 processor supports wireless protocols and combines an open−programmable controller with hardware accelerators for audio coding and error correction support. Ezairo 7100 also includes a programmable Filter Engine that enables time domain filtering and supports an ultra−low−delay audio path.

Offering the industry’s lowest power consumption in deep sleep and peak receiving, RSL10 is a highly flexible multi−protocol 2.4 GHz radio specifically designed for use in high−performance wearable and medical applications. With its Arm Cortex−M3 processor and LPDSP32 DSP core, RSL10 supports Bluetooth low energy technology and 2.4 GHz proprietary protocols.
