SC28L92  
3.3 V/5.0 V Dual Universal Asynchronous  
Receiver/Transmitter (DUART)  
Rev. 07 — 19 December 2007  
Product data sheet  
1. General description  
The SC28L92 is a pin and function replacement for the SCC2692 and SC26C92 operating  
at 3.3 V or 5 V supply with added features and deeper FIFOs. Its configuration on  
power-up is that of the SC26C92. Its differences from the SCC2692 and SC26C92 are:  
16 character receiver, 16 character transmit FIFOs, watchdog timer for each receiver,  
mode register 0 is added, extended baud rate and overall faster speeds, programmable  
receiver and transmitter interrupts. (Neither the SC26C92 nor the SCC2692 is being  
discontinued.)  
Pin programming will allow the device to operate with either the Motorola or Intel bus  
interface. The bit 3 of the MR0A register allows the device to operate in an 8 byte FIFO  
mode if strict compliance with the SC26C92 FIFO structure is required.  
The NXP Semiconductors SC28L92 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 with 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 28  
fixed baud rates; a 16× clock derived from a programmable counter/timer, or an external  
1× or 16× 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 8 or 16 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 SC28L92 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 SC28L92 is available in three package versions: PLCC44, QFP44, and HVQFN48.
