The XR17V258 (V258) is a single chip 8-channel  
66MHz PCI (Peripheral Component Interconnect)  
UART (Universal Asynchronous Receiver and  
Transmitter)  
solution,  
optimized  
for  
higher  
FEATURES  
performance and lower power. The V258 device with  
its fifth generation register set is designed to meet the  
High performance 32-bit 66MHz PCI UART  
PCI 3.0 compliance  
PCI power management rev. 1.1 compliance  
EEPROM interface for PCI configuration  
3.3V supply with 5V tolerant non-PCI (serial) inputs  
Data read/write burst operation  
Global interrupt register for all eight UART channels  
Up to 8 Mbps serial data rate  
Eight multi-purpose inputs/outputs

power  
management  
requirements for multi-serial communication ports for  
system administration and management. The 32-bit  
66MHz PCI interface is compliant with PCI 3.0 and  
PCI power management revision 1.1 specifications.  
The device provides an upgrade path for Exar’s  
33MHz 5V and Universal PCI UART family of  
products in a 144-pin LQFP package.  
The V258 consists of eight independent UART  
channels, each with set of configuration and  
enhanced registers, 64 bytes of Transmit (TX) and  
Receive (RX) FIFOs, and a fractional Baud Rate  
Generator (BRG). A global interrupt source register  
provides a complete interrupt status indication for all  
8-channels to speed up interrupt parsing. The V258  
device operates at 33/66MHz and features fully  
programmable TX and RX FIFO level triggers,  
automatic hardware and software flow control, and  
automatic RS-485 half duplex direction control output  
for software and hardware design simplification.  
A 16-bit general purpose timer/counter  
Sleep mode with wake-up Indicator  
Eight independent UART channels controlled with  
16C550 compatible register Set  
64-byte TX and RX FIFOs with level counters  
and programmable trigger levels  
Fractional baud rate generator  
Automatic RTS/CTS or DTR/DSR hardware  
flow control with programmable hysteresis  
Automatic Xon/Xoff software flow control  
RS-485 half duplex direction control output  
with selectable turn-around delay
