XR16M2750 - HIGH PERFORMANCE DUART

General Description

The XR16M27501 (M2750) is a high performance dual universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs.

The device operates from 1.62 to 3.6 volts and is pin-to-pin compatible to Exar’s ST16C2550 and XR16V2750.

Key Features

  • It supports the Exar’s enhanced features of 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 data rates up to 8 Mbps at 3.3.
