MaxLinear, Inc. UARTs (Universal Asynchronous Receiver Transmitter) XR16M580IM48-F

The XR16M580IM48-F is a high-performance Universal Asynchronous Receiver Transmitter (UART) from Quarktwin Technology Ltd. It features 16 bytes of transmit and receive FIFOs, with selectable FIFO trigger levels, and supports data rates up to 16 Mbps at 3.3V, 12.5 Mbps at 2.5V, and 7.5 Mbps at 1.8V using a 4X data sampling rate. The device includes automatic hardware and software flow control, as well as an Auto RS-485 half-duplex direction control feature, which simplifies design for half-duplex applications. This UART supports independent TX/RX baud rate generation, allowing for different baud rates for transmission and reception. It operates within a supply voltage range of 1.62V to 3.63V and includes power-saving modes such as sleep mode and PowerSave mode to minimize power consumption. The XR16M580IM48-F is compatible with both Intel and Motorola bus interfaces, making it versatile for various applications, including personal digital assistants, cellular phones, and battery-operated devices. The device is available in a 48-pin TQFP package and is suitable for environments with operating temperatures ranging from -40¬8C to +85¬8C.
