XR16M2551 Datasheet High Performance Low Voltage Duart

Manufacturer: Exar (now MaxLinear)

Overview: .. MAY 2007 XR16M2551 HIGH PERFORMANCE LOW VOLTAGE DUART WITH 16-BYTE FIFO AND POWERSAVE FEATURE REV. 1.0.

General Description

The XR16M25511 (M2551) is a high performance dual universal asynchronous receiver and transmitter (UART) with 16 byte TX and RX FIFOs.

The device operates from 1.62 to 3.63 volts and is pin-to-pin patible to the XR16L2551 and XR16V2551.

The M2551 includes 2 additional capabilities over the XR16M2550: Intel and Motorola data bus selection and a “PowerSave” mode to minimize the sleep current.

Key Features

  • of selectable FIFO trigger level, automatic hardware (RTS/CTS) and software flow control, 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 16 Mbps at 3.3 Volt and 4X sampling clock. The M2551 is available in 48-pin TQFP and 32-pin QFN packages. NOTE: 1 Covered by U. S. Patent #5,649,122.
