Description

Description

The XR16C2850 (2850) is an enhanced dual universal asynchronous receiver and transmitter (UART). Enhanced features include 128 bytes of TX and RX FIFOs, programmable TX and RX FIFO trigger level, FIFO level counters, automatic (RTS/CTS) hardware and (Xon/Xoff) software flow control, automatic RS-485 half duplex direction control output and data rates up to 6.25 Mbps at 5V and 8X sampling clock. Onboard status registers provide the user with operational status and data error flags. An internal loopback capability allows system diagnostics. The 2850 has a full modem interface and can operate at 2.97V to 5.5V and is pin-to-pin compatible to Exar's ST16C2550 and XR16L2750 except the 48-TQFP package. The 2850 register set is compatible to the industry standard ST16C2550 and is available in 48-pin TQFP and 44-pin PLCC packages.
