The PI7C8952 is a PCI® Dual UART (Universal Asynchronous Receiver-Transmitters) I/O Bridge. It is specifically designed to meet various system requirements of high performance and lead (Pb) -free. The bridge can be used in a wide range of applications such as Remote Access Servers, Automation, Process Control, Instrumentation, POS, ATM and Multi-port RS232/RS422/RS485 Cards. The PI7C8952 provides standard PCI® connection, and it is fully compliant with 32-bit PCI Bus 2.3 specifications. The bridge supports two high performance UARTs, each of which supports Baud rate up to 15 Mbps in asynchronous mode.
The UARTs support in-band and out-band auto flow control, arbitrary trigger level, I/O mapping and memory mapping,m IrDA (Infrared Data Association) encoder/decoder, 8 general purpose I/O and 16-bit timer counter. The PI7C8952 is fully software compatible with 16C550 type device drivers and can be configured to fit the requirements of RS232, RS422 and RS485 applications. The EEPROM interface is provided for system implementation convenience. Some registers can be pre-programmed via hardware pin settings to facilitate system initialization. For programming flexibility, all of the default configuration registers can be overwritten by EEPROM data, such as sub-vendor and sub-system ID.
PCI Specification, Revision 2.3 compliance
