EZAIRO 7160 SL HYBRID
Wireless-Enabled Audio
Processor for Hearing Aids
Introduction
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.
Development Tools
Ezairo Preconfigured Suite (Pre Suite)*
The Ezairo Pre Suite provides a complete framework to easily
develop Ezairo−based hearing aids and fitting software. Included in
the Ezairo Pre Suite is a pre−loaded firmware bundle, configuration
software, and a cross−platform Software Development Kit (SDK) to
develop your own fitting software.
RSL10 Development Tools
The RSL10 development tools provide an Eclipse−based SDK
complete with Bluetooth profiles and wireless audio codecs for the
RSL10’s Arm Cortex−M3 processor. The RSL10’s LPDSP32 code
can be developed using the Synopsys development tools which are
available by request.
Open−Programmable Evaluation and Development Kit (EDK)
To develop your own firmware on Ezairo 7160 SL, the Ezairo 7100
Evaluation and Development Kit (EDK) includes optimized hardware,
programming interface, and a comprehensive Integrated Development
Environment (IDE).
*This datasheet describes all features of the Ezairo 7160 SL hybrid module. Not
all of these features are available using the Ezairo Preconfigured Suite.
