Am186CC CONTROLLER CUSTOMER
DEVELOPMENT PLATFORM
The Am186CC controller customer development platform is provided as a test and development platform for the Am186CC controller. Most of the controller’s features and options can be exercised on this platform. Because there are numerous options and debug features available, this platform is a much larger form factor than could be achieved with a dedicated set of features. This evaluation platform can be used to experiment with design tradeoffs and develop firmware or software for the Am186CC controller.
