Product Summary

The SC26C92C1B is a dual universal asynchronous receiver. 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 SC26C92C1B is a single-chip CMOS-LSI communications device that provides two full-duplex asynchronous receiver/transmitter channels in a single package. The SC26C92C1B interfaces directly with microprocessors and may be used in a polled or interrupt driven system and provides modem and DMA interface.
