Product Summary
The XR16V554IV-F 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 XR16V554IV-F 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-F(64-pin) offers three state interrupt output while the XR16V554DIV provides continuous interrupt output. The XR16V554IV-F is compatible with the industry standard ST16C554. Applications include Portable Appliances, Telecommunication Network Routers, Ethernet Network Routers, Cellular Data Devices and Factory Automation and Process Controls.
