Description

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. The complete status of each channel of the quadruple ACE can be read by the CPU at any time during operation. The information obtained includes the type and condition of the operation performed and any error conditions encountered. TL16C554A Features • Integrated Asynchronous-Communications Element• Consists of Four Improved TL16C550C ACEs Plus Steering Logic• In FIFO Mode, Each ACE Transmitter and Receiver Is Buffered With 16-Byte FIFO to Reduce the Number of Interrupts to CPU• In TL16C450 Mode, Hold and Shift Registers Eliminate Need for Precise Synchronization Between the CPU and Serial Data• Up to 16-MHz Clock Rate for up to 1-Mbaud Operation with VCC= 3.3 V and 5 V• Programmable Baud-Rate Generators Which Allow Division of Any Input Reference Clock by 1 to (216-1) and Generate an Internal 16 ×Clock• Adds or Deletes Standard Asynchronous Communication Bits (Start, Stop, and Parity) to or From the Serial-Data Stream• Independently Controlled Transmit, Receive, Line Status, and Data Set Interrupts• 5-V and 3.3-V Operation
