Introduction; Features - Motorola RAM104 User Manual

Introduction

This chapter provides information on the PM603 and PM604
Processor/Memory mezzanine modules and the RAM104 DRAM Memory
mezzanine modules. These are add-on modules intended for use with the
MVME160x base boards. In addition, product specifications, cooling
requirements, and EMC compliance data are provided in Appendix B.
Note Although both the PM603 and PM604 are discussed in this
manual, the PM604 is only available as a part of a factory
configured MVME160x bundle. It is no longer available as a
stand-alone part number.
