PCI BUS TARGET INTERFACE
• A general purpose PCI bus target interface
• Multiplexed and de-multiplexed 32-, 16-, or 8-
bit local bus interface
• Fully compliant with PCI 2.1 specification
• Large, 288-byte FIFOs using V3’s unique
DYNAMIC BANDWIDTH ALLOCATION™ architecture
• On-the-fly byte order (endian) conversion
including automatic endian detection
• Address space remapping
• Mailboxes w/doorbell interrupts
• Flexible PCI and local interrupt management
• Serial EEPROM configuration interface
• 33MHz local bus with independent PCI bus
operation up to 33MHz
• Low cost 160-pin EIAJ PQFP package
The V300PSC provides the highest
performance, most flexible, and most economical
method to connect a general purpose 32-, 16-, 8-
bit local bus to the PCI bus. V3 Semiconductor’s
simple to use local bus interface makes the
V300PSC the fastest route to adding PCI to your
system. The V300PSC may be used in systems
without a CPU for a generic PCI target interface.
The V300PSC supports independent interface
speeds allowing the PCI bus to run at the full
33MHz frequency, regardless of local bus clock
rate. The V300PSC uses the unique DYNAMIC
BANDWIDTH ALLOCATION™ FIFOs to decouple the
local and PCI bus, while dramatically improving
the overall throughput of the system.
A PCI master can gain access to the local bus
through two programmable address apertures
with address remapping capabilities, and on-the-
fly byte order conversion.
To support existing DOS I/O devices a special
decoder mode allows up to 3 I/O regions (and
one memory region below 1MB) to be decoded.
The V300PSC’s interrupt control mechanism is
very flexible and allows interrupts from multiple
sources on the local bus to share a single PCI
interrupt.
The V300PSC operates up to 33MHz, and is
packaged in a low cost, 160-pin EIAJ Plastic
Quad Flat Pack (PQFP) package.
