106 Error Checking Module (ECM)
Q:
The MPC106 Rev. 4 Supplement indicates that provision for an in-line external
Error Checking Module (ECM) has been added for use with SDRAM. Could you
provide any additional application information about using an ECM with the
MPC106? Also, sources/specs of ECC modules that would be appropriate for this
application?
A:
There are no commercially available modules. The feature was added to the 106
Rev 4.0 for a specific customer that needed SDRAM with ECC, so they developed a
proprietary registered transceiver/ECC module. We have a one page requirements
sheet that shows a block diagram and some timing for an external error checking
module. Beyond distributing the module requirements, we have no plans to
support the external module interface.
