Description
Standard PCI Local Bus Specification Rev. 2.3 Compliant
Built-In PCI Target Controller @ 33/66MHz
Zero-Wait PCI Conversion and 24ns UART response time for IOR & IOW
Dedicated Auto Control Pins for RS422 and RS485 Bus Networking
Global Interrupt and Interrupt Vector Processing
SB16C1054PCI is a single chip which enables 4 asynchronous serial communication ports to be connected to the PCI bus without any glue logic and it is the best solution to constitute a serial port for the PCI bus. It allows customers to make easy and simple reference design as a one-chip solution for 4-port serial multi-port cards.
It includes SB16C1054, Quad-UART with 256-byte TX/RX FIFO developed by SystemBase. It also has enhanced features: global interrupt and dedicated control pins for RS422/485 auto toggling. The 256-byte FIFOs reduce CPU overhead and allow higher data throughput.
