HD68562

HD68562 DUSCC (Dual Universal Serial Communications Controller) The HD68562 Dual Universal Serial Communications Controller (DUSCC) transforms parallel data which is transferred from central processing unit into serial data_ It is a single chip MOS-LSI communications device designed to be a foundation of universal high-performance data-communication subsystems, particularly for the 68000 family microprocessors_ The DUSCC provides two independent, multi-protocol, full duplex receiver/transmitter channels in a single package_ Since the DUSCC supports a wide range of protocols, it handles data communications with the minimum intervention, usually just a few commands from its host processor. The controller's data rate is maximum 4M bits/s which meets the requirement of the presently most powerful systems. A high-speed, high-performance communication system is realized with minimum extemallogic at low cost through a variety of functions prOvided by the chip: 16-bit multi-function counter/...
