MSP50C604 Datasheet (Texas Instruments)

MSP50C604, MIXED-SIGNAL PROCESSORS

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.

The computational unit uses a powerful new DSP that gives the MSP50C604 unprecedented speed

MSP50C604 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 shar
