TL16C554A ACE

The TL16C554A is an enhanced quadruple version of the TL16C550C asynchronous-communications element (ACE). Each channel performs serial-to-parallel conversion on data characters received from peripheral devices or modems and parallel-to-serial conversion on data characters transmitted by the CPU. Th.

TL16C554A, TL16C554AI ASYNCHRONOUS-COMMUNICATIONS ELEMENT D Integrated Asynchronous-Communications Element D Consists of Four Improved TL16C550C ACEs Plus Steering Logic D In FIFO Mode, Each ACE Transmitter and Receiver Is Buffered With 16-Byte FIFO to Reduce the Number of Interrupts to CPU D In TL16C450 Mode, Hold and Shift Registers Eliminate Need for Precise Synchronization Between the CPU and Serial Data D Up to 16-MHz Clock Rate for up to 1-Mbaud Operation with VCC = 3.3 V and 5 V D Progra.
