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 (TI literature number SPSU012).

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages are with respect to ground.
2. The total supply current includes the current out of all the I/O terminals and DAC terminals as well as the operating current of the
device.
