SC68C94 Overview
The 68C94 quad universal asynchronous receiver/transmitter (QUART) bines four enhanced Philips Semiconductors industry-standard UARTs with an innovative interrupt scheme that can vastly minimize host processor overhead. It is implemented using Philips Semiconductors’ high-speed CMOS process that bines small die size and cost with low power consumption. The operating speed of each receiver and transmitter can be...
