SCC2698B
Enhanced octal universal asynchronous
receiver/transmitter (Octal UART)

2006 Aug 07
DESCRIPTION
The SCC2698B Enhanced Octal Universal Asynchronous
Receiver/Transmitter (Octal UART) is a single chip MOS-LSI
communications device that provides eight full-duplex asynchronous
receiver/transmitter channels in a single package. It is fabricated
with CMOS technology which combines the benefits of high density
and low power consumption.
The operating speed of each receiver and transmitter can be
selected independently as one of 26 fixed baud rates, a 16X clock
derived from a programmable counter/timer, or an external 1X or
16X clock. The baud rate generator and counter/timer can operate
directly from a crystal or from external clock inputs. The ability to
independently program the operating speed of the receiver and
transmitter make the Octal UART particularly attractive for
dual-speed channel applications such as clustered terminal
systems.
The receiver is quadruple buffered to minimize the potential of
receiver overrun or to reduce interrupt overhead in interrupt driven
systems. In addition, a handshaking (RTS/CTS) capability is
provided to disable a remote UART transmitter when the receiver
buffer is full.
The UART provides a power-down mode in which the oscillator is
frozen but the register contents are stored. This results in reduced
power consumption on the order of several magnitudes. The Octal
UART is fully TTL compatible and operates from a single +5V power
supply.
The SCC2698B is an upwardly compatible version of the 2698A
Octal UART. In PLCC packaging, it is enhanced by the addition of
receiver ready or FIFO full status outputs, and transmitter empty
status outputs for each channel on 16 multipurpose I/O pins. The
multipurpose pins of the 2698B RIO pins, thus DMA and modem
control is provided.

NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other condition above those indicated in the operation section of this specification is not
implied.
2. For operating at elevated temperatures, the device must be derated based on +150
°C maximum junction temperature.
3. This product includes circuitry specifically designed for the protection of its internal devices from damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying any voltages larger than the rated maxima.
4. Parameters are valid over specified temperature range. See ordering information table for applicable temperature range and operating
supply range.
