General Information

Introduction

The Universe VMEbus interface chip (CA91C042) provides a reliable
high performance 64-bit VMEbus to PCI interface in one device.
Designed by Tundra Semiconductor Corporation in consultation with
Motorola, the Universe is compliant with the VME64 specification and is
tuned to the new generation of high speed processors.
The Universe is ideally suited for CPU boards acting as both master and
slave in the VMEbus system, and is particularly fitted for PCI local
systems. The Universe is manufactured in a CMOS process.
