XR16M2751 - HIGH PERFORMANCE DUART

General Description

The XR16M27511 (M2751) 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 and software compatible to Exar’s XR16V2751.

Key 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. An internal loopback capability allows system diagnostics. Independent programmable fractional baud rate generators are provided in each channel to select data rates up to 8 Mbps at 3.3 Volt and 8X sampling clock. The M2751 is available in a 48-pin TQFP package. NOTE: 1 Covered by U. S. Patent #5,6.
