MSP50C37

The MSP50C37 uses a revolutionary architecture to combine 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 ms. The MSP50C37 features two independent channels of linear predictive coding (LPC), which synthesize high-quality speech at a low data rate. Pulse-code modulation (PCM) of MSP50C37 can produce music or sound effects. LPC and PCM can be added together to produce a composite result.
