Description
The MSP50C604 is a low-cost, mixed-signal processor that combines a speech synthesizer with a dedicated slave interface logic, 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. Slave mode consists of four general-purpose I/O, four control pins, and eight bidirectional data pins. A simple one-bit comparator is also included in the periphery. The comparator is enabled by a control register, and its access is shared with two pins in one general-purpose I/O port. Rounding out the MSP50C604 periphery is a built-in pulse-density-modulated DAC (digital-to-analog converter) with direct speaker-drive.
