XR16L580  
SMALLEST 2.25V TO 5.5V UART WITH 16-BYTE FIFO AND POWERSAVE  
JANUARY 2004  
REV.1.2.0  
FEATURES  
GENERAL DESCRIPTION  
Industry Smallest Full Featured UART  
2.25V to 5.5V Operation  
The XR16L580 (L580) is a 2.25 to 5.5 volt Universal  
Asynchronous Receiver and Transmitter (UART) with  
5 volt tolerant inputs and a reduced pin count. It is  
pin-to-pin and software compatible to industry  
standard 16C450, 16C550, ST16C580, ST16C650A  
and XR16C850 UARTs. It has 16 bytes of TX and RX  
FIFOs and is capable of operating up to serial data  
rate of 1 Mbps at 2.25 volt supply voltage. The  
internal registers is compatible to the 16C550  
register set plus enhanced registers for additional  
features to support today’s high bandwidth data  
communication needs. The enhanced features  
include Intel or Motorola data bus interface to match  
your CPU interface, automatic hardware and  
software flow control to prevent data loss, selectable  
RX and TX trigger levels for more efficient interrupt  
service, wireless infrared (IrDA) encoder/decoder for  
wireless applications and a unique Power-Save mode  
to increase battery operating time. The device comes  
in the 48-TQFP and a very small 32-QFN packages in  
industrial temperature range.  
5V Tolerant Inputs  
Intel/Motorola Bus Select  
’0 ns’ Address Hold Time (TAH and TADH  
)
Pin and Software Compatible to industry standard  
16C450, 16C550, ST16C580, ST16C650A and  
XR16C850 in the 48-TQFP package.  
16-byte Transmit FIFO  
16-byte Receive FIFO with Errors Flags  
Selectable RX and TX FIFO Trigger Levels  
Automatic Hardware (RTS/CTS) Flow Control  
Automatic Software (Xon/Xoff) Flow Control  
Up to 3.125 Mbps Data Rate at 5V and 2 Mbps at  
3.3V and 1 Mbps at 2.25V Operation with External  
Clock Input  
Infrared (IrDA) Encoder/Decoder  
Complete Modem Interface  
APPLICATIONS  
Power-Save Mode to conserve battery power  
Sleep Mode with Wake-up Interrupt  
Small 32-QFN (5x5x0.9mm) package  
Handheld Terminals and Tablets
