The MSP50C604 is a low-cost, mixed-signal processor that combines a speech synthesizer with a dedicated slave interface logic, general-purpose I/O, onboard ROM, and direct speaker-drive in a single package. The computational unit uses a powerful new DSP that gives the MSP50C604 unprecedented speed and computational flexibility compared with previous devices of its type. The MSP50C604 supports a variety of speech and audio coding algorithms, providing a range of options with respect to speech duration and sound quality.
