XR16V654D 2.25V to 3.6V Quad UART with 64-Byte FIFO

The XR16V6541 (V654) is an enhanced quad Universal Asynchronous Receiver and Transmitter (UART) each with 64 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 16 Mbps at 4X sampling rate. 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 V654 is available in a 48-pin QFN, 64-pin LQFP, 68-pin PLCC, 80-pin LQFP and 100-pin QFP packages. The 64-pin and 80-pin packages only offer the 16 mode interface, but the 48, 68 and 100 pin packages offer an additional 68 mode interface which allows easy integration with Motorola processors. The XR16V654IV (64-pin) offers three state interrupt output while the XR16V654DIV provides continuous interrupt output. The 100 pin package provides additional FIFO status outputs (TXRDY# and RXRDY# A-D), separate infrared transmit data outputs (IRTX A-D) and channel C external clock input (CHCCLK). The XR16V654 is compatible with the industry standard ST16C554 and ST16C654/654D
