The XR16V5541 (V554) is a quad Universal Asynchronous Receiver and Transmitter (UART) with 16 bytes of transmit and receive FIFOs, selectable receive FIFO trigger levels and data rates of up to 4 Mbps at 3.3 V. Each UART has a set of registers that provide the user with operating status and control, receiver error indications, and modem serial interface controls. An internal loopback capability allows onboard diagnostics. The V554 is available in a 48-pin QFN, 64-pin LQFP, 68-pin PLCC and 80-pin LQFP packages. The 64-pin and 80-pin packages only offer the 16 mode interface, but the 48- and 68-pin packages offer an additional 68 mode interface which allows easy integration with Motorola processors. The XR16V554IV (64-pin) offers three state interrupt output while the XR16V554DIV provides continuous interrupt output. The XR16V554 is compatible with the industry standard ST16C554.\nNOTE: 1Covered by U.S. Patent #5,649,122\nFor UART technical support or to obtain an IBIS model for this product, please email Exar's UART Technical Support group.\n
