Infineon OPTIGA Trust E Security Shield2Go User manual

OPTIGA™ Trust E
Security Shield2Go
Quick Start
V1.0.0

Introduction
OPTIGA™ Trust E is a high-security solution for industrial automation systems,
smart homes, consumer or medical devices, providing enhanced protection of
services, business models and user experience. Based on its 1-way authentication
mechanism, it uniquely identifies objects and protects PKI networks.
The turnkey set-up with full system integration and all key material
preprogrammed aims to minimize your efforts in order to maintain a fast and easy
integration. The high-end security controller comes with OS, embedded application
and complete host side integration support and is moreover compliant to the new
USB Type-C standard.

Features include a high-end security controller with
advanced cryptographic algorithms implemented in
hardware (ECC256), a turnkey solution with OS, Applet
and complete host-side integration support as well as
full system integration support with up to 3 kBytes user
memory.
The communication interface is I2C and the device
supports ECC 256 bit and SHA-256.

Evaluation Board Notes
Information
•Supply voltage VCC is max. 7 V, please refer to
the OPTIGA™ Trust E datasheet for more details
about maximum ratings
•Pin out on top (head) is directly connected to the
pins of the OPTIGA™ Trust E
•If head is broken off, only one capacitor is
connected to the OPTIGA™ Trust E
•Software compatible with Arduino and library fully
integrated into the Arduino IDE
•Sales Name S2Go Security OPTIGA E and OPN
S2GOSECURITYOPTIGAETOBO1
Ensure that no voltage applied to any of the pins
exceeds the absolute maximum rating of VCC + 0.3 V

Example with XMC 2Go
Notes
•The Shield2Go form factor of the Shield2Go
evaluation board is directly compatible with the
XMC 2Go board
•Stack the OPTIGA™ Trust E Security Shield2Go
board on top of the XMC 2Go as shown in the
picture
•The additional pin on the left-top side (designated
with NC) is left floating
•Using the XMC-for-Arduino Arduino integration, the
Arduino library for the OPTIGA™ Trust E can be
directly used
https://github.com/Infineon/XMC-for-Arduino
https://github.com/Infineon/OPTIGA-Trust-E-Security-Controller
Steps
•Open one of the examples for the OPTIGA™ Trust E from File –Examples
and select as board XMC1100 XMC2Go
•Connect the stacked boards to the PC and press the Upload button
•Select the related COM port from Tools –Port and open the serial monitor with
the set baud rate (see sketch/code with Serial.begin(<BAUDRATE>);)

Important Note
Important Note
•The OPTIGA™ Trust E has a maximum
rating of 7 V on the VCC supply pin
•The input voltage on any pin should
not exceed VCC+0.3 V
•Third party boards with 5 V logic, e.g.
the Arduino Uno, can be connected to
the OPTIGA™ Trust E Security
Shield2Go directly
