General Description

The Epic Ei68C684/Ei88C684 Quad Universal Asynchronous Receiver and Transmitter (QUART) is a data communication device that provides four fully independent full duplex asynchronous communication channels in a single package.

The QUART is designed for use in microprocessor based systems and may be used in a polled or interrupt driven environment.

Two basic versions of the QUART are pin selectable with SEL pin and each is optimized for use with various microprocessor families: the Ei88C684 for 8080/5, 8086/88, Z80, Z8000, 68XX and 65XX family based systems., and the 68C681 for 68000 family based systems.and the Ei68C684 for 68000family based systems A programmable mode of the Ei88C684 versions provides an interrupt daisy chain for use in Z80 and Z8000 based systems.

Key Features
