Description



The XR16M26511 (M2651) is a high performance dual universal asynchronous receiver and transmitter (UART) with 32 byte TX and RX FIFOs. The device operates from 1.62 to 3.63 volts and is pin-to-pin and software compatible to the XR16V2551 and XR16L2551. The device includes 2 additional capabilities over the XR16M2650: Intel and Motorola data bus selection and a "PowerSave" mode to minimize the sleep current. It supports Exar's enhanced 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 with 4X sampling clock. The M2651 is available in 48-pin TQFP and 32-pin QFN packages.

NOTE: 1Covered by U.S. Patent #5,649,122
