Microprocessors Procurement Notes

Verify component status as obsolete or end-of-life through official manufacturer channels before design finalization. Confirm availability of legacy stock or alternative sourcing strategies if current production has ceased. Ensure all technical specifications align with existing system requirements given the discontinued nature of this specific part number.

Microprocessors Selection Notes

Select this component only if dual-core ARM926EJ-S performance meets computational needs without requiring newer architectures. Evaluate compatibility with existing DDR memory standards and interface protocols. Consider the long-term maintenance implications of using an obsolete MPU in new designs versus migrating to supported families.
