description
The MSP50C30 combines an 8-bit microprocessor, two speech synthesizers, ROM, RAM, and I/O in a low-cost
single-chip system. The architecture uses the same arithmetic logic unit (ALU) for the two synthesizers and the
microprocessor, thus reducing chip area and cost and enabling the microprocessor to do a multiply operation
in 0.8 µs. The MSP50C30 features two independent channels of linear predictive coding (LPC), which
synthesize high-quality speech at a low data rate. Pulse-code modulation (PCM) can produce music or sound
effects. For more information, see the MSP50C30 User’s Guide (literature number SPSU012).
