CompuLab Ltd. IPC2 – Hardware Specification Page 49 of 83
4.6 Super-I/O Controller
IPC2 design provides RS232 serial communication between Data Terminal Equipment (Host) and
Data Communication Equipment (Device) by the means of Super-I/O Controller SMSC SIO1007,
which implements LPC Bus to UART Bridge. The SIO1007 implements the LPC interface with the
LPC PortSwitch interface. The LPC PortSwitch interface is a hot switchable external docking LPC
interface. It also features a full 16bit internally decoded address bus, a Serial IRQ interface with
PCI clock support, relocatable configuration ports and three DMA channel options.
The SIO1007 incorporates one complete 8-pin UART.
