XR16L2750 - 2.25V TO 5.5V DUART

Description

The XR16L27501 (2750) is a low voltage dual universal asynchronous receiver and transmitter (UART) with 5 Volt tolerant inputs.

The device operates from 2.25 to 5.5 Volt supply range and is pin-to-pin compatible to Exar’s ST16C2550 and XR16C2850 except the 48-TQFP package.

Features

  • It supports the Exar’s enhanced features of 64 bytes of TX and RX FIFOs, programmable FIFO trigger level and FIFO level counters, automatic hardware (RTS/CTS) and software flow control, automatic RS-485 half duplex direction control output and a complete modem interface. Onboard registers provide the user with operational status and data error flags. An internal loopback capability allows system diagnostics. Independent programmable baud rate generators are provided in each channel to select da.
