MPC107 Revision 1.3 and 1.4: Comparison and Compatibility
For a few years now, the production revision of the MPC107 has been Rev 1.3. However, this version of the device is limited to a processor/memory bus frequency of 100 MHz and has errata that some customers have deemed unsuitable for their design requirements. Recently a new revision of the MPC107, Rev 1.4, was introduced to implement fixes for the errata to make it more suitable for new designs. Specification changes that manufacturing supports also addressed the frequency limitation. Because many existing designs are unaffected by the 100-MHz limit and the errata on Rev 1.3, and because Rev 1.4 introduces timing and functional changes to the 107, many customers choose to continue specifying Rev 1.3 in their designs. This document, which describes the differences between Rev 1.3 and Rev 1.4,provides help to assess which revision is appropriate for a specific design and what changes might be necessary when migrating a system design from Rev 1.3 to Rev 1.4.
