SC16C754B
5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs

Functional description
The SC16C754B UART is pin-compatible with the SC16C554 and SC16C654 UARTs. It
provides more enhanced features. All additional features are provided through a special
enhanced feature register.
The UART will perform serial-to-parallel conversion on data characters received from
peripheral devices or modems, and parallel-to-parallel conversion on data characters
transmitted by the processor. The complete status of each channel of the SC16C754B
UART can be read at any time during functional operation by the processor.
The SC16C754B can be placed in an alternate mode (FIFO mode) relieving the processor
of excessive software overhead by buffering received/transmitted characters. Both the
receiver and transmitter FIFOs can store up to 64 bytes (including three additional bits of
error status per byte for the receiver FIFO) and have selectable or programmable trigger
levels. Primary outputs RXRDY and TXRDY allow signalling of DMA transfers.
The SC16C754B has selectable hardware ow control and software ow control.
Hardware ow control signicantly reduces software overhead and increases system
efciency by automatically controlling serial data ow using the RTS output and CTS input
signals. Software ow control automatically controls data ow by using programmable
Xon/Xoff characters.
The UART includes a programmable baud rate generator that can divide the timing
reference clock input by a divisor between 1 and (216
1).
6.1 Trigger levels
The SC16C754B provides independent selectable and programmable trigger levels for
both receiver and transmitter DMA and interrupt generation. After reset, both transmitter
and receiver FIFOs are disabled and so, in effect, the trigger level is the default value of
one byte. The selectable trigger levels are available via the FIFO Control Register (FCR).
The programmable trigger levels are available via the Trigger Level Register (TLR).

Crystal or external clock input. Functions as a crystal input or as an
external clock input. A crystal can be connected between XTAL1 and
XTAL2 to form an internal oscillator circuit (see Figure 14). Alternatively,
an external clock can be connected to this pin to provide custom data
rates.
