PRODUCT FEATURES
x Inter-operable with VIA Host-to-V-Link Host Controller
Combine with VT8754 (Apollo P4X333) for a complete 533 / 400 MHz FSB Pentium 4 system
Combine with VT8377 (Apollo KX400) for a complete 266 / 200 MHz FSB Athlon Socket-A system
x High Bandwidth 533 MB/s 8-bit V-Link Client Controller
Supports 66 MHz V-Link Client interface with total bandwidth of 533 MB/sec
V-Link operates in 2x, 4x, and 8x modes
Full duplex commands with separate Strobe / Command
Request / Data split transaction
Configurable outstanding transaction queue for V-Link Client accesses
Auto Client Retry to eliminate V-Link Host-Client Retry cycles
Intelligent V-Link transaction protocol to eliminate data wait-state / throttle transfer latency; all V-Link transactions
for both Host and Client have a consistent view of transaction data depth and buffer size to avoid data overflow.
Highly efficient V-Link arbitration with minimum overhead; all V-Link transactions have predictable cycle length
with known Command / Data duration
Auto connect / reconnect capability and dynamic stop for minimum power consumption
Parity checking to insure correct data transfers
x Integrated Peripheral Controllers
Integrated Fast Ethernet Controller with 1 / 10 / 100 Mbit capability
Integrated USB 2.0 Controller with three root hubs and six function ports
Dual channel UltraDMA-133 / 100 / 66 / 33 master mode EIDE controller
AC-link interface for AC-97 audio codec and modem codec
HSP modem support
Integrated DirectSound compatible digital audio controller
LPC interface for Low Pin Count interface to Super-I/O or ROM
x Integrated Legacy Functions
Integrated Keyboard Controller with PS2 mouse support
Integrated DS12885-style Real Time Clock with extended 256 byte CMOS RAM and Day/Month Alarm for ACPI
Integrated DMA, timer, and interrupt controller
Serial IRQ for docking and non-docking applications
Fast reset and Gate A20 operation
