General description
The SC16C654B/654DB is a Quad 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 SC16C654B/654DB is pin compatible with the ST16C654 and TL16C754 and it will
power-up to be functionally equivalent to the 16C454. Programming of control registers
enables the added features of the SC16C654B/654DB. Some of these added features are
the 64-byte receive and transmit FIFOs, automatic hardware or software ow control and
infrared encoding/decoding. The selectable auto-ow control feature signicantly reduces
software overload and increases system efciency while in FIFO mode by automatically
controlling serial data ow using RTS output and CTS input signals. The
SC16C654B/654DB also provides DMA mode data transfers through FIFO trigger levels
and the TXRDY and RXRDY signals. (TXRDY and RXRDY signals are not available in the
HVQFN48 package.) 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 SC16C654B/654DB operates at 5 V, 3.3 V and 2.5 V, and the industrial temperature
range, and is available in plastic PLCC68, LQFP64, HVQFN48 and LFBGA64 packages.
On the HVQFN48 package, only channel C has all the modem pins. Channel A and
channel B have only RTS and CTS pins, and channel D does not have any modem pin.
