MSP50C614 MIXED-SIGNAL PROCESSORS

The MSP50C614 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 MSP50C614 unprecedented speed and computational flexibility compared with previous devices of its type. The MSP50C614 suppor.

Features

make the input port especially useful as a key-scan interface. A simple one-bit comparator is also included in the periphery. The comparator is enabled by a control register, and its pin access is shared with two pins in one of the general-purpose I/O ports. Rounding out the MSP50C614 periphery is a built-in pulse-density-modulated DAC (digital-to-analog converter) with direct speaker-drive capability. .
