5 pcs. philips# SC16C554IB80, quad uart with 16-byte fi
The following item has just been added to our store in a larger qty. This item is for 5 pcs. only!
IC Quad UART with 16-byte FIFO and infrared (IrDA)
UART's (Universal Asynchronous Receiver Transmitter)
The SC16C554/554D is a 4-channel Universal Asynchronous Receiver and
Transmitter (QUART) used for serial data communications. Its principal function is to
convert parallel data into serial data and vice versa. The UART can handle serial data
rates up to 5 Mbits/s. It comes with an Intel or Motorola interface.
The SC16C554/554D is pin compatible with the ST16C554 and TL16C554 and it will
power-up to be functionally equivalent to the 16C454. Programming of control
registers enables the added features of the SC16C554/554D. Some of these added
features are the 16-byte receive and transmit FIFOs, automatic hardware or software
flow control and Infrared encoding/decoding. The selectable auto-flow control feature
significantly reduces software overload and increases system efficiency while in FIFO
mode by automatically controlling serial data flow using RTS output and CTS input
signals. The SC16C554/554D also provides DMA mode data transfers through FIFO
trigger levels and the TXRDY and RXRDY signals. On-board status registers provide
the user with error indications, operational status, and modem interface control.
System interrupts may be tailored to meet user requirements. An internal loop-back
capability allows on-board diagnostics.
