Description
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.
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.
