5.1 CryptoAuth Trust Platform Connections
The 2-lead µVSFN has a dedicated SWI-PWM connection through the mikroBUS header that enables it to connect to the mikroBUS host header present on the Trust Platform or any of the PIC/AVR/SAM MCU host development boards that have a mikroBUS header. The SWI-PWM connection is always connected to the host micro on the Trust Platform board.
Connecting the 2-Lead µVSFN to the CryptoAuth Trust Platform
- Configure the EV98D91A to the desired mode as specified in Modes of Operation.
- Set the switches on the
CryptoAuth Trust Platform to disable the on-board devices. Note that the SW2_1
switch will have no effect on this mikroBUS board. This setting is highlighted
in bold and italic below:
Switch Settings What is Enabled SW2_1 SW2_2 mikroBUS™ Header On-Board Devices N/A ON Yes Yes N/A OFF Yes No - Connect the two boards as shown
in the following figure.

Remember: The angled notch on the 2-lead µVSFN must be aligned with the angled line on the silk screen near the mikroBUS connector. - Connect a USB cable between the CryptoAuth Trust Platform on the host system where the software is developed.
- Invoke the software tools for the given application or the use case that is being developed.
