CA0189 is a highly-integrated, high-performance system-on-chip designed specifically for a range of lower end, cost-sensitive audio products. CA0189 provides more features and performance than any other available solution, at the lowest possible system cost. In addition, due to the use of an industry-standard processor, a wide range of off-the-shelf software is immediately available.
