ST16C554 / ST16C554D / ST68C554 Data Sheet 2.97V to 5.5V Quad UARTs with 16-Byte FIFO General Description The ST16C554, ST16C554D and ST68C554 are each quad Universal Asynchronous Receivers and Transmitters (UARTs) with 16 bytes of transmit and receive FIFOs, selectable receive FIFO trigger levels, and data rates of up to 1.5Mbps. 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 ST16C554 is available in a 64-pin LQFP package, the ST16C554D is available in both a 64-pin LQFP and a 68-pin PLCC package, and the ST68C554 is available in a 68-pin PLCC package.
