Datasheet Summary
TL16C554A, TL16C554AI ASYNCHRONOUS-MUNICATIONS ELEMENT
D Integrated Asynchronous-munications
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 Programmable Baud-Rate Generators
Which Allow Division of Any Input Reference Clock by 1 to (216
- 1) and Generate an Internal 16 × Clock
D Adds or Deletes Standard Asynchronous munication Bits (Start,...
