Description
- The TL16C554IFN is an Asynchronous Communications Element features that 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 at any time during functional operation by the CPU. The information obtained includes the type and condition of the operation performed and any error conditions encountered. The 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. To minimize system overhead and maximize system efficiency, all logic is on the chip. Two terminal functions allow signalling of direct memory access (DMA) transfers.
- False start bit detection
- Complete status reporting capabilities
- Line break detection and generation
- Loopback controls for communications link fault isolation

- Fully prioritized interrupt system controls
- 3-state Outputs provide TTL drive capabilities for bidirectional data bus and control bus
- MODEM control functions (CTS, RTS, DSR, DTR, RI and DCD)
- Consists of four improved TL16C550 ACEs plus steering logic
- Adds or deletes standard asynchronous communication bits to or from the serial-data stream
- Up to 16-MHz clock rate for up to 1-Mbaud operation
- Green product and no Sb/Br
