COM2651 - SMSC

COM2651 Programmable Communication Interface

The COM 2651 is an MaS/LSI device fabricated using SMC's patented COPLAMOS® technology that meets the majorit)' of asynchronous and synchronous data communication requirements, by interfacing parallel digital systems to asynchronous and synchronous data communication channels while requiring a minimum of processor overhead. The COM 2651 contains a baud rate.
