ST16C650A  
2.90V TO 5.5V UART WITH 32-BYTE FIFO  
REV. 5.0.0  
JANUARY 2004  
FEATURES  
GENERAL DESCRIPTION  
Added features in top mark date code of "HC YYWW"  
and newer:  
The ST16C650A1 (650A) is a 2.90 to 5.5 volt  
Universal Asynchronous Receiver and Transmitter  
(UART) with 5 volt tolerant inputs. This device  
supports Intel and PC ISA mode data bus interfaces  
and is software compatible to industry standard  
16C450, 16C550, ST16C580 and ST16C650A  
UARTs.  
2.90 to 5.5 Volt Operation  
5 Volt Tolerant Inputs  
Automatic RS485 Half-Duplex Control Output  
Programmable Infrared Encoder Pulse Width  
Sleep Mode with Wake-up Indicator  
Device ID & Revision  
The 650A has 32 bytes of TX and RX FIFOs and is  
capable of operating up to serial data rates of 3.125  
Mbps at 5 volt supply voltage. The internal registers  
include the 16C550 register set plus Exar’s enhanced  
registers for additional features to support today’s  
highly demanding data communication needs. The  
enhanced features include automatic hardware and  
software flow control, selectable TX and RX trigger  
levels, and wireless infrared (IrDA) encoder/decoder.  
Up to 3.125 Mbps Data Rate at 5 Volts  
Added feature in top mark date code of "I2 YYWW"  
and newer:  
0 ns address hold time  
Intel or PC Mode 8-bit Bus Interface  
32-byte Transmit and Receive FIFOs  
Automatic Hardware (RTS/CTS) Flow Control  
Hardware Flow Control Hysteresis  
Automatic Software (Xon/Xoff) Flow Control  
The device provides a new capability to give user the  
ability to program the wireless infrared encoder  
output pulse width, hence reducing the power  
consumption of a handheld unit.  
APPLICATIONS  
The ST16C650A device comes in the 44-pin PLCC  
and 48-pin TQFP packages in both the commercial  
and industrial temperature ranges.
