Product Summary
The ST16C554DIJ68-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 1.5 Mbps. 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 ST16C554DIJ68-F is available in a 64-pin LQFP and a 68-pin PLCC package. The 64-pin package only offers the 16 mode interface, but the 68-pin package offers an additional 68 mode interface which allows easy integration with Motorola processors. The applications of the ST16C554DIJ68-F include portable Appliances, telecommunication Network Routers, ethernet Network Routers, cellular Data Devices, factory Automation and Process Controls.
