STEVAL-ISA164V1

STEVAL-ISA164V1 STNRG388A evaluation board Data brief Description 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 Features PC. STNRG controllers integrate a serial All STNRG388A pins available on interface which can be used to extend the connectors STNRG388A communication capabilities via Convenient tool for validating SMED Bluetooth, WiFi or powerline modems. The algorithms STEVAL-ISA164V1 evaluation board can be Graphical interface for SMED configuration powered in three different ways: by external On-board components for tutorial power supply, USB or via the SWIM interface. Micro-USB port for PC connectivity The board features several free footprint areas USB, external or SWIM power supply which are ideal for connecting power drivers or SWIM interface with STLINK or RLINK amplifiers. An additional free PCB footprint allows connectors the user to connect a quartz clock, which can be Four extra footprint areas for SOT23-6 and used in place of the STNRG388A internal clock. one for SO8 One external clock (HSE) footprint area October 2015 DocID028549 Rev 1 1/14 www.st.com For further information contact your local STMicroelectronics sales office Board details STEVAL-ISA164V1 1 Board details Table 1: STEVAL-ISA164V1 electrical specifications Parameter Value J3, Voltage 3.0 V min. to 5.5 V max J3, Current 100 mA J1, Voltage 5 V typ.
