August 2000

Dear Valued Customer:

Thank you for your purchase of a Motorola MVME172P-series Embedded Controller. These

products, which incorporate the new “Petra” ASIC, provide owners of existing MVME172

boards a means of migrating to updated boards while preserving their investments in associated

software and equipment. The information in this letter applies to those MVME172 products

built to support 4 IP (IndustryPack) modules.

Background

Due to evolution in technology, the production of certain ASICs used on first- and second-

generation MVME162/172 series boards has ended. The discontinued ASICs are the MC, MC2,

IPIC, IP2, and MCECC chips. The Petra chip was developed to replace these discontinued

ASICs.

The Petra ASIC is functionally compatible with each of the components that it replaces. In cases

where functionality between the previous ASICs is exclusive, configuration switches or

jumpers are provided to let you select the desired functionality. For instance, the MC and MC2

chips differed in their implementation of Flash write protection. Boards built with the Petra

ASIC, accordingly, have a configuration switch so that you can determine which method to use.

Motorola is committed to providing long-term support for the widely used 68K product family.

In order to continue offering this family of products and to maintain the current programming

model, large quantities of end-of-life parts have been procured and the boards have been

redesigned to use newer component technologies where necessary. While these new products

are designed for compatibility with previous 68K family products, some differences do exist.

New Models

The new MVME172 board will be offered in the versions listed in the table below. Existing

applications should be mapped to one of these versions. If that is not possible, please contact

your local Motorola sales office for assistance.
