XR16C850CMTR - Brand New EXAR UARTs (Universal Asynchronous Receiver Transmitter)
-
Description
The XR16C850CMTR is a universal asynchronous receiver and transmitter (UART). It is pin compatible with the ST16C550, ST16C650A, and TI's TL16C750 UART and is an enhanced UART with 128 byte FIFOs, automatic hardware/software flow control and data rates up to 1.5Mbps. The XR16C850CMTR includes transmit/receive FIFO counters to increase data loading and unloading throughput. It also includes onboard status registers that provide error indications and operational status. The XR16C850CMTR features RS-485 half duplex direction control and can be optionally configured to operate with the Infrared (IrDA) encoder/decoder. It has internal loopback that allows onboard diagnostics and comes in a small 7x7mm TQFP package.
