Z16C3010VEG Universal Serial Controller (USC) is a dual-channel multi-protocol data communications peripheral designed for use with any conventional multiplexed or non multiplexed bus. The USC functions as a serial-to-parallel, parallel-to-serial converter/controller and may be software configured to satisfy a wide variety of serial communications applications. The device contains a variety of new, sophisticated internal functions including two baud rate generators per channel, one digital phase-locked loop (DPLL) per channel, character counters for both receive and transmit in each channel and 32-byte dataFIFO's for each receiver and transmitter
