T100A

The T100A is a highly integrated All-in-one Visual Processor that provides major cost saving soluTIon for the portable applicaTIons. T100A has built-in high performance Triple ADCs, TCON, Triple DACs, Scaling Machine with sophisTIcated upscaling and downscaling algorithms. The InnovaTIve integrated “Frame-Buffer-Less” De-interlacer can significantly reduce system cost. The T100A also integrates On Screen Display engine with 3K-word of font RAM. The device can interface to an external micro-controller through 2-wire serial bus interface.
