– Standard PCI Local Bus Specification Rev. 2.3 Compliant
– Built-In PCI Target Controller @ 33/66MHz
– Built-In 2 Improved 16C1050 UART with 256 Byte FIFO
– Global Interrupt and Control Pins for RS422/485 Auto Toggling
– Supports H/W and S/W Flow Control
SB16C1052PCI is a single chip which enables 2 asynchronous serial communication ports to be connected to a PCI bus without any glue logic and it is the best solution to constitute a serial port for the PCI bus. It allows customer to make easy and simple reference design as a one-chip solution for 1 port or 2 ports multi-port serial cards. It includes SB16C1052, Dual 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.
