Demonstration Board
Functional Description

The SD188ES/SD188EM demonstration board provides a completely stand-alone
microcontroller-based evaluation platform in a low-cost, exceptionally small form-
factor product. The SD188ES/SD188EM demonstration board was designed to
meet the needs of customers working with the Am188ES and Am188EM
microcontrollers.
