General description
The SC16C554B/554DB 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 Mbit/s. It comes with an Intel
or Motorola
interface.
The SC16C554B/554DB 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 SC16C554B/554DB. Some of these added features are
the 16-byte receive and transmit FIFOs, four receive trigger levels. The
SC16C554B/554DB 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.
The SC16C554B/554DB operates at 5 V, 3.3 V and 2.5 V, and the industrial temperature
range, and is available in plastic PLCC68, LQFP64, and LQFP80 packages.
