Description



The XR16M581¹ (M581) is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with a VLIO bus interface and has 16 bytes of transmit and receive FIFOs, programmable transmit and receive FIFO trigger levels, automatic hardware and software flow control, and data rates of up to 20 Mbps at 3.3V, 16 Mbps at 2.5V and 10 Mbps at 1.8V with 4X data sampling rate.

The Auto RS-485 Half-Duplex Direction control feature simplifies both the hardware and software for half-duplex RS-485 applications. In addition, the Multidrop mode with Auto Address detection increases the performance by simplifying the software routines.

The Independent TX/RX Baud Rate Generator feature allows the transmitter and receiver to operate at different baud rates. Power consumption of the M581 can be minmized by enabling the sleep mode and PowerSave mode.

The XR16M581 has a 16550 compatible register set that provide users with operating status and control, receiver error indications, and modem serial interface controls. An internal loopback capability allows onboard diagnostics. The M581 is available in 24-pin QFN, 32-pin QFN and 25-pin BGA packages.

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