INTEGRATED CIRCUITS SC26C92 Dual universal asynchronous receiver/transmitter (DUART) Product specification Supersedes data of 1998 Nov 09 IC19 Data Handbook 2000 Jan 31 Philips Semiconductors Philips Semiconductors Product specification Dual universal asynchronous receiver/transmitter (DUART) SC26C92 DESCRIPTION The SC26C92 is a pin and function replacement for the SCC2692 and SCN2681 with added features and deeper FIFOs. Its configuration on power up is that of the 2692. Its differences from the 2692 are: 8 character receiver, 8 character transmit FIFOs, watch dog timer for each receiver, mode register 0 is added, extended baud rate and overall faster speeds, programmable receiver and transmitter interrupts. (The SCC2692 is not being discontinued.) The Philips Semiconductors SC26C92 Dual Universal Asynchronous Receiver/Transmitter (DUART) is a single-chip CMOS-LSI communications device that provides two full-duplex asynchronous receiver/transmitter channels in a single package. It interfaces directly with microprocessors and may be used in a polled or interrupt driven system and provides modem and DMA interface. The operating mode and data format of each channel can be programmed independently. Additionally, each receiver and transmitter can select its operating speed as one of 27 fixed baud rates, a 16X clock derived from a programmable counter/timer, or an external 1X or 16X clock. The baud rate generator and counter/timer can operate directly from a crystal or from...
