DESCRIPTION
The SC26C92 is a pin and function replacement for the SCC2692
and SCN2681 with added features and deeper FIFOs. Its
configuration on power up is that of the 2692. Its differences from
the 2692 are: 8 character receiver, 8 character transmit FIFOs,
watch dog timer for each receiver, mode register 0 is added,
extended baud rate and overall faster speeds, programmable
receiver and transmitter interrupts. (The SCC2692 is not being
discontinued.)
The Philips Semiconductors SC26C92 Dual Universal
Asynchronous Receiver/Transmitter (DUART) is a single-chip
CMOS-LSI communications device that provides two full-duplex
asynchronous receiver/transmitter channels in a single package. It
interfaces directly with microprocessors and may be used in a polled
or interrupt driven system and provides modem and DMA interface.
The operating mode and data format of each channel can be
programmed independently. Additionally, each receiver and
transmitter can select its operating speed as one of 27 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 DUART particularly
attractive for dual-speed channel applications such as clustered
terminal systems.
Each receiver and transmitter is buffered by eight character FIFOs
to minimize the potential of receiver overrun, transmitter underrun
and to reduce interrupt overhead in interrupt driven systems. In
addition, a flow control capability is provided via RTS/CTS signaling
to disable a remote transmitter when the receiver buffer is full.
Also provided on the SC26C92 are a multipurpose 7-bit input port
and a multipurpose 8-bit output port. These can be used as general
purpose I/O ports or can be assigned specific functions (such as
clock inputs or status/interrupt outputs) under program control.
The SC26C92 is available in three package versions: 40-pin 0.6”
wide DIP, a 44-pin PLCC and 44–pin plastic quad flat pack (PQFP).
