Description
The Microchip SIO1007 is a 3.3V PC 99 and ACPI 1.0
compliant Super I/O Controller. The SIO1007 imple-
ments the LPC interface with the
LPC PortSwitch
Interface. T
he
LPC PortSwitch Interface is a hot-
switchable 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 con-
figuration ports and three DMA channel options. The
part also includes 16 GPIO pins.
The SIO1007 incorporates one 8-pin 16C550A com-
patible UART. In addition, the SIO1007 provides a sec-
ond 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 recom-
mended 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 regis-
ters. There are 192 I/O address location options, a
Serialized IRQ interface, and three DMA channels.

TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
E-mail at
docerrors@microchip.com.
We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for cur-
rent devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the
revision of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site;
http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include -literature number) you are
using.
