Purpose
This manual provides information on the configuration
and use of the Ezairo 7160 SL Hybrid Demonstrator Board.
The demonstrator board is designed to be used with the
Ezairo Preconfigured Suite (Pre Suite), or the Ezairo 7100
Open−Programmable Evaluation and Development Kit
(EDK) to develop wireless−enabled hearing aids based on
the Ezairo 7160 SL.

BOARD DESIGN & OVERVIEW
Introduction
The Ezairo 7160 SL Hybrid Demonstrator Board is
designed to easily develop high−performance hearing aids
based on the Ezairo 7160 SL hybrid. The miniature,
wireless−enabled hybrid includes an Ezairo 7100 audio
processor, RSL10 Bluetooth
EEPROM memory (EA2M) and passive components. The
board features many configuration options available via
standard 0.1" header pins, and an on−board J−Link debugger
based on the Atmel ATSAM3U2CA−AU microcontroller.
Using a USB cable, the on−board debugger is used to
interface the RSL10 radio within the Ezairo 7160 SL hybrid
with a PC for debugging, data collection, or monitoring
purposes.
Two versions of the Ezairo 7160 SL demonstrator board
are available. The first board is the E7160SL−001GEVB
which contains an elastomer socket and is designed for
general use. This version of the board is recommended for
development, testing and debug purposes since it enables the
Ezairo 7160 SL module contained in the socket to be easily
swapped out. During development, testing or debug, it may
happen that the Ezairo 7160 SL enters a state where it no
longer operates as expected − for example, due to improper
manipulation of data in the EEPROM. In such a case, the
user can take advantage of being able to easily replace the
hybrid module on this version of the board. For this reason,
onsemi recommends using the E7160SL− 001GEVB during
development.
The second board is the E7160SL−002GEVB which is
optimized for RF testing and characterization. The Ezairo
7160 SL hybrid is directly reflowed on the board, which
minimizes the impedance between the onboard matching
network and the Ezairo 7160 SL.
Note: The E7160SL−001GEVB doesn't contain an Ezairo
7160 SL module, which are sampled separately. The
