I/O Controller LPC Controller 64-Pin STQFP

The Microchip SIO1007 is a 3.3V PC 99 and ACPI 1.0 compliant Super I/O Controller. The SIO1007 implements the LPC interface with the LPC PortSwitch Interface. The LPC PortSwitch Interface is a hotswitchable external Docking LPC interface with trusted cycle block. The SIO1007 also features a full 16-bit internally decoded address bus, a Serial IRQ interface with PCI nCLKRUN support, relocatable configuration ports and three DMA channel options. The part also includes 16 GPIO pins. The SIO1007 incorporates one 8-pin 16C550A compatible UART. In addition, the SIO1007 provides a second UART to support a Serial Infrared Interface that complies with IrDA v1.2 (Fast IR), HPSIR, and ASKIR formats, as well as Consumer IR. There is a second IR port, which supports NEC PPM and RC5, as well as Consumer IR protocols. The SIO1007 incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes. The SIO1007 also features Software Configurable Logic (SCL) for ease of use. SCL allows programmable system configuration of key functions such as the UARTs. The SIO1007 supports the ISA Plug-and-Play Standard register set (Version 1.0a) and provides the recommended functionality to support Windows ‘9x, 2K, ME, XP and PC99. The I/O Address, DMA Channel and Hardware IRQ of each device in the SIO1007 may be reprogrammed through the internal configuration registers. There are 192 I/O address location options,
