XR16C850 UART with 128-byte FIFO’s FIFO Counters and Half-duplex Control June 1999-1 GENERAL DESCRIPTION The XR16C850*1 (850) is a universal asynchronous receiver and transmitter (UART) and is pin compatible with the ST16C550,ST16C650A, and TI’s TL16C750 UART. The 850 is an enhanced UART with 128 byte FIFOs, automatic hardware/software flow control, and data rates up to 1.5Mbps. It includes transmit/receive FIFO counters to increase data loading and unloading throughput. Onboard status registers provide error indications and operational status. Modem interface control is included and can be optionally configured to operate with the Infrared (IrDA) encoder/decoder. Internal loopback allows onboard diagnostics.
