Key Features

Features for the TL16C554A

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 V_CC = 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
Fully Programmable Serial Interface Characteristics:
- 5-, 6-, 7-, or 8-Bit Characters
- Even-, Odd-, or No-Parity Bit
- 1-, 1 1/2-, or 2-Stop Bit Generation
- Baud Generation (DC to 1-Mbit Per Second)
False Start Bit Detection
Complete Status Reporting Capabilities
Line Break Generation and Detection
Internal Diagnostic Capabilities:
- Loopback Controls for Communications Link Fault Isolation
- Break, Parity, Overrun, Framing Error Simulation
Fully Prioritized Interrupt System Controls
Modem Control Functions (CTS, RTS, DSR, DTR, RI, and DCD)
3-State Outputs Provide TTL Drive Capabilities for Bidirectional Data Bus and Control Bus
Programmable Auto-RTS and Auto-CTS
CTS Controls Transmitter in Auto-CTS Mode,
RCV FIFO Contents and Threshold Control RTS in Auto-RTS Mode,
