The MSP50C601 is a low-cost, mixed-signal processor that combines a speech synthesizer, general-purpose I/O, onboard ROM, and direct speaker drive in a single package. The computational unit utilizes a powerful new DSP which gives the MSP50C601 unprecedented speed and computational flexibility compared with previous devices of its type. The MSP50C601 supports a variety of speech and audio coding algorithms, providing a range of options for speech duration and sound quality. The device consists of a micro-DSP core, embedded program, and data memory, and a self-contained clock generation system. General-purpose periphery is comprised of 32 bits of partially configurable I/O. The core processor is a general-purpose 16-bit microcontroller with DSP capability. The basic core block includes computational unit (CU), data address unit, program address unit, two timers, eight level interrupt processor, and several system and control registers. The core processor gives the MSP50C601 break-point capability in emulation.
