■ DESCRIPTIONS
S1C17555/565/955/965 can operate at high speed with low power and it has large address area.
These products have good points such as Space-saving package (WCSP), 12-bit A/D converter and Signal
processing accelerator(FSA) every model and selectable depending on a use.
In FSA, signal processing ranging from image processing to audio handling is possible.
S1C17955/965 is most suitable for the application such as mobile devices. FSA realize high processing with a low
clock, and realize a low consumption design by using this function.
