The STEVAL-ISA164V1 evaluation board is designed to help familiarize the user with the STNRG family of digital controllers and their innovative SMED (state machine, event driven) architecture. A convenient GUI enables the user to quickly generate the optimal SMED configuration for the application. The external pins make it easy to inject SMED events and capture the SMED-controlled PWM clock, thereby helping the user to validate the SMED configuration. Alternatively, the application circuit can be driven directly from the evaluation board. The board provides a micro-USB connector to allow programming, GUI connectivity and configuration via a terminal utility running on a PC. STNRG controllers integrate a serial interface which can be used to extend the STNRG388A communication capabilities via Bluetooth, WiFi or powerline modems. The STEVAL-ISA164V1 evaluation board can be powered in three different ways: by external power supply, USB or via the SWIM interface. The board features several free footprint areas which are ideal for connecting power drivers or amplifiers. An additional free PCB footprint allows the user to connect a quartz clock, which can be used in place of the STNRG388A internal clock.
