SC28L91

INTEGRATED CIRCUITS SC28L91 3.3V–5.0V Universal Asynchronous Receiver/Transmitter (UART) Product specification Supersedes data of 2000 Apr 03 2000 Sep 22 Philips Semiconductors Philips Semiconductors Product specification 3.3V–5.0V Universal Asynchronous Receiver/Transmitter (UART) SC28L91 DESCRIPTION The SC28L91 is a new member of the IMPACT family of Serial Communications Controllers. It is a single channel UART operating at 3.3 and 5.0 volts Vcc, 8 or 16 byte FIFOs and is quite compatible with software of the SC28L92 and previous UARTs offered by Philips. It is a new part that is similar to our previous one channel part but is vastly improved. The improvements being: 16 character receiver, 16 character transmit FIFOs, watch dog timer for the receiver, mode register 0 is added, extended baud rate, over all faster bus and data speeds, programmable receiver and transmitter interrupts and versatile I/O structure. (The previous one channel part, SCC2691, is NOT being discontinued.) Pin programming will allow the device to operate with either the Motorola or Intel bus interface. Bit 3 of the MR0 register allows the device to operate in an 8-byte FIFO mode if strict compliance with an 8-byte FIFO structure is required. The Philips Semiconductors SC28L91 Universal Asynchronous Receiver/Transmitter (UART) is a single-chip CMOS-LSI communications device that provides a full-duplex asynchronous receiver/transmitter channel in a single package. It interfaces directly with micro...
