2 Overview
The OM-SE050ARD is the development kit for the SE050 Plug & Trust product family.
This kit allows you to evaluate the SE050 product family features and simplifies
the development of your custom applications. Figure 1 shows a picture of the OM-
SE050ARD.

The SE050 uses I
2
C as communication interface and its commands are wrapped using
the Smartcard T=1 over I²C (T=1oI2C) protocol. In addition, the SE050 supports the
following interfaces:
• I
2
C interface in slave mode with date rates up to 3.4 Mbps .
• I
2
C interface in master mode with date rates up to 400 Khz.
• ISO/IEC 14443 T=CL protocol.
The OM-SE050ARD flexible design makes it possible to access the SE050 interfaces by
just changing a few jumper settings.
Note: Only the I
2
C slave interface is mandatory. The I
2
C master and ISO/IEC 14443
interfaces are optional.
