LC823231
Overview
LC823231 is a dual decoder LSI that supports MP3/WMA. This LSI has realized super low power consumption that is
not available in DSP base construction by specializing the MP3/WMA decode function to make an exclusive circuit as a
hard-wired construction. The main characteristics are as follows.
Features
Super low power consumption (Around 10mW)
