SCC2691
Universal asynchronous receiver/transmitter (UART)

2006 Aug 04
DESCRIPTION
The Philips Semiconductors SCC2691 Universal Asynchronous
Receiver/Transmitter (UART) is a single-chip CMOS-LSI
communications device that provides a full-duplex asynchronous
receiver/transmitter. It is fabricated with Philips Semiconductors
CMOS technology which combines the benefits of high density and
low power consumption.
The operating speed of the receiver and transmitter can be selected
independently as one of 18 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 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 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 UART is fully TTL compatible and operates from a single +5V
power supply.
FEATURES
Full-duplex asynchronous receiver/transmitter
Quadruple buffered receiver data register
Programmable data format:
– 5 to 8 data bits plus parity
– Odd, even, no parity or force parity
– 1, 1.5 or 2 stop bits programmable in 1/16-bit increments
16-bit programmable Counter/Timer
Baud rate for the receiver and transmitter selectable from:
– 22 fixed rates: 50 to 115.2K baud
– Non-standard rates to 115.2 kb
– Non-standard user-defined rate derived from programmable
timer/ counter
– External 1X or 16X clock
