The XR16L580 (L580) is a 2.25 to 5.5 volt Universal Asynchronous Receiver and Transmitter (UART) with 5 volt tolerant inputs and a reduced pin count. It is pin-to-pin and software compatible to industry standard 16C450, 16C550, ST16C580, ST16C650A, and XR16C850 UARTs. It has 16 bytes of TX and RX FIFOs and is capable of operating up to serial data rate of 1 Mbps at 2.25 volt supply voltage. The internal registers is compatible to the 16C550 register set plus enhanced registers for additional features to support today’s high bandwidth data communication needs. The enhanced features include Intel or Motorola data bus interface to match your CPU interface, automatic hardware and software flow control to prevent data loss, selectable RX and TX trigger levels for more efficient interrupt service, wireless infrared (IrDA) encoder/decoder for wireless applications and a unique Power-Save mode to increase battery operating time. The device comes in the 48-TQFP and very small 32-QFN, 28-QFN and 24-QFN packages in industrial temperature range.\nFor UART technical support or to obtain an IBIS model for this product, please email Exar's UART Technical Support group.\n
