description

The MSP50x3x family 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

µs. The MSP50x3x family 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. LPC and PCM can be added together to produce a

composite result. For more information, see the MSP50x3x User’s Guide (literature number SPSU006).
