1.2.2.2 VT8235 CE
The VT8235 Version CE South Bridge is a high integration, high performance, power-efficient, and high
compatibility device that supports Intel and non-Intel based processor to V-Link bus bridge functionality to
make a complete Microsoft PC2001-compliant PCI/LPC system. The VT8235 Version CE includes standard
intelligent peripheral controllers:
a) IEEE 802.3 compliant 10 / 100 Mbps PCI bus master Ethernet MAC with standard MII interface to
external PHYceiver
b) 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 VT8235 Version CE 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.
c) Universal Serial Bus controller that is USB v2.0 / 1.1 and Universal HCI v2.0 / 1.1 compliant. The
VT8235 Version CE includes three root hubs with six function ports with integrated physical layer
transceivers. The USB controller allows hot plug and play and isochronous peripherals to be inserted
into the system with universal driver support. The controller also implements legacy keyboard and
mouse support so that legacy software can run transparently in a non-USB-aware operating system
environment.
d) Keyboard controller with PS2 mouse support.

e) Real Time Clock with 256 byte extended 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.
f) 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.
g) Full System Management Bus (SMBus) interface.
h) Integrated bus-mastering dual full-duplex direct-sound AC97-link-compatible sound system.
i) Plug and Play controller that allows complete steerability of all PCI interrupts and internal interrupts /
DMA channels to any interrupt channel. One additional steerable interrupt channel is provided to allow
plug and play and reconfigurability of on-board peripherals for Windows family compliance.
The VT8235 Version CE also enhances the functionality of the standard ISA peripherals. The integrated
interrupt controller supports both edge and level triggered interrupts channel by channel. The integrated DMA
controller supports type F DMA in addition to standard ISA DMA modes. Compliant with the PCI-2.2
specification, the VT8235 Version CE supports delayed transactions and remote power management so that
slower ISA peripherals do not block the traffic of the PCI bus. Special circuitry is built in to allow
concurrent operation without causing dead lock even in a PCI-to-PCI bridge environment. The chip also
includes eight levels (double words) of line buffers from the PCI bus to the ISA bus to further enhance
overall system performance.
