8399 N/B Maintenance

￿ IEEE 802.3 compliant 10 / 100 Mbps PCI bus master Ethernet MAC with standard MII interface to external PHYceiver.

￿ Master mode enhanced IDE controller with dual channel DMA engine and interlaced dual channel

commands. Dedicated FIFO coupled with scatter and gather master mode operation allows high

performance transfers between PCI and IDE devices. In addition to standard PIO and DMA mode operation,

the VT8235CD also supports the UltraDMA-133, 100, 66, and 33 standards to allow reliable data transfer at

rates up to 133 MB/sec. The IDE controller is SFF-8038i v1.0 and Microsoft Windows-family compliant.

 

Secret

￿ Universal Serial Bus controller that is USB v2.0 / 1.1 and Universal HCI v2.0 / 1.1 compliant. The

VT8235CD includes three root hubs with six fun tion ports with integrated physical layer transceivers. The

USB controller allows hot plug and play and isochronous peripherals to be inserted into the system with

MiTac

 

universal driver support. The controller lso implements legacy keyboard and mouse support so that legacy

software can run transparently n

non-USB-aware operating system environment.

Confidential

￿ Keyboard controller with PS2 mouse support.

 

￿ Real Time Clock with 256 byte

xt nded CMOS. In addition to the standard ISA RTC functionality, the

integrated RTC also includes the date alarm, century field, and other enhancements for compatibility with

the ACPI standard.

 

 

￿ Notebook-class power management functionality compliant with ACPI and legacy APM requirements.

 

Multiple sleep states (power-on suspend, suspend-to-DRAM, and suspend-to-Disk) are supported with

 

hardware automatic wake-up. Additional functionality includes event monitoring, CPU clock throttling and

 

stop (Intel processor protocol), PCI bus clock stop control, modular power, clock and leakage control,

 

hardware-based and software-based event handling, general purpose I/O, chip select and external SMI.

 

￿ Full System Management Bus (SMBus) interface.
