Audio Processor, Wireless-Enabled DSP for Hearing Aids

Favorite

Overview

Enabling wireless connectivity in hearing aids, Ezairo® 7150 SL is an open-programmable DSP-based hybrid module that supports Bluetooth® low energy technology and other 2.4 GHz wireless protocols.

What's Included in Ezairo 7150 SL

  • Ezairo 7100 Digital Signal Processor (DSP): Includes a high precision, quad-core architecture that delivers 375 MIPS without sacrificing power consumption.
  • Radio IC: Powerful wireless transceiver to support Bluetooth low energy technology and proprietary 2.4 GHz protocols
  • EA2M: 2 Mb EEPROM memory for storing important hearing aid parameters and firmware

Development Tools
  • Ezairo Preconfigured Suite
  • Open-Programmable Evaluation & Development Kit (EDK)

To access Ezairo-based development tools, please contact your Sales Representative or Authorized Distributor.

Please note that Ezairo 7150 SL is not recommended for new designs. Instead, we recommend the Ezairo 7160 SL wireless-enabled DSP for Hearing Aids.
