SB16C1053APCI is a PCI target interface controller with dual-UART, single parallel port and MIO Bus. It offers easy PCI target card implementation for serial port and parallel port. The SB16C1053APCI provides high performance serial and parallel port communication. With a built-in 2 SB16C1050A core that has built-in 256-byte FIFO, SB16C1053APCI decreases CPU load. It detects errors such as overrun error and works well with simultaneous use of multiple ports. Furthermore, it is capable of waking up PC that is powered off through interrupts or wake-up requests with PCI power management implemented. The SB16C1053APCI supports up to 6 serial ports, providing RS422/485 auto toggling function and global interrupt function to built-in UART allowing a more convenient handling of serial communication at the driver level. Finally, with SB16C1053APCI, it is easy to design various types of serial and parallel multi-port products as shown below:
– 1-port Serial Multi-Port PCI Card (1S mode)
– 2-port Serial Multi-Port Card (2S mode)
– 4-port Serial Multi-Port Card (4S mode)
– 6-port Serial Multi-Port Card (6S mode)
– 1-port Parallel Multi-Port Card (1P mode)
– 2-port Serial and 1-port Parallel Multi-Port Card (2S1P mode)
