Product Information

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
  • 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,

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.

The TL16C554A quadruple ACE can be placed in an alternate FIFO mode, which activates the internal FIFOs to allow 16 bytes (plus three bits of error data per byte in the receiver FIFO) to be stored in both receive and transmit modes. In the FIFO mode of operation, there is a selectable autoflow control feature that can significantly reduce software overhead and increase system efficiency by automatically controlling serial-data flow using RTS\ output and CTS\ input signals. All logic is on the chip to minimize system overhead and maximize system efficiency. Two terminal functions allow signaling of direct-memory access (DMA) transfers. Each ACE includes a programmable baud-rate generator that can divide the timing reference clock input by a divisor between 1 and 216-1.

The TL16C554A is available in a 68-pin plastic-leaded chip-carrier (PLCC) FN package and in an 80-pin (TQFP) PN package.
