SIO1007 LPC Super I/O LPC IrDA Hot Docking Chip with UART TM Interface LPC PortSwitch Product Features - Secondary Switchable LPC Interface (3.3V 3.3 Volt Operation (5V tolerant) only) Programmable Wakeup Event Interface - Trusted cycles blocked (IO PME Pin) - Buffered 14 MHz output SMI Support (IO SMI Pin) - Switched PCI Clock output GPIOs (16) Programmable internal pull-up resistors Description Two IRQ Input Pins The Microchip SIO1007 is a 3.3V PC 99 and ACPI 1.0 XNOR Chain compliant Super I/O Controller. The SIO1007 imple- PC99a and ACPI 1.0 Compliant ments the LPC interface with the LPC PortSwitch 64-Pin STQFP RoHS Compliant Package Interface. The LPC PortSwitch Interface is a hot- Intelligent Auto Power Management switchable external Docking LPC interface with One Full Function Serial Port trusted cycle block. The SIO1007 also features a full 16-bit internally decoded address bus, a Serial IRQ - High Speed 16C550A Compatible UARTs interface with PCI nCLKRUN support, relocatable con- with Send/Receive 16-Byte FIFOs figuration ports and three DMA channel options. The - Supports 230k and 460k Baud part also includes 16 GPIO pins. - Programmable Baud Rate Generator The SIO1007 incorporates one 8-pin 16C550A com- - Modem Control Circuitry patible UART. In addition, the SIO1007 provides a sec- Infrared Communications Controller ond UART to support a Serial Infrared Interface that - Three IR Ports complies with IrDA v1.2 (Fast IR), HPSIR, and ASKIR - Multi-Protocol Serial Communications Con- formats, as well as Consumer IR. There is a second IR trollers port, which supports NEC PPM and RC5, as well as Consumer IR protocols. - Two IrDA v1.2 (4Mbps), HPSIR, ASKIR, Con- sumer IR Support The SIO1007 incorporates sophisticated power control - One Consumer IR Port with support for NEC circuitry (PCC). The PCC supports multiple low power PPM and RC5 with PME Wake-up Option down modes. The SIO1007 also features Software Configurable Logic (SCL) for ease of use. SCL allows - Multiple Base I/O Address options, 15 IRQ programmable system configuration of key functions Options and 3 DMA Options such as the UARTs. LPC Bus Host Interface - Supports LPC Bus frequencies of 19.2MHz to The SIO1007 supports the ISA Plug-and-Play Standard register set (Version 1.0a) and provides the recom- 33MHz mended functionality to support Windows 9x, 2K, ME, - Multiplexed Command, Address and Data XP and PC99. The I/O Address, DMA Channel and Bus Hardware IRQ of each device in the SIO1007 may be - 8-Bit I/O Transfers reprogrammed through the internal configuration regis- - 8-Bit DMA Transfers ters. There are 192 I/O address location options, a - 16-Bit Address Qualification Serialized IRQ interface, and three DMA channels. - Serial IRQ Interface Compatible with Serial- ized IRQ Support for PCI Systems - PCI nCLKRUN Support - Power Management Event (IO PME ) Inter- face Pin 2005 - 2014 Microchip Technology Inc.
