XR16C2850 - 2.97V TO 5.5V DUAL UART

General Description

The XR16C28501 (2850) is an enhanced dual universal asynchronous receiver and transmitter (UART).

Key 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 RS485 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 3.3 V or 5 V and.
