Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'GCQB' against official Infineon documentation to confirm package type and lead-free status. Ensure compatibility with existing board designs regarding pinout and electrical specifications. Confirm availability through authorized channels due to the specialized nature of radiation-hardened components.

Application Specific Microcontrollers Selection Notes

Select this component when radiation tolerance and military temperature ranges are mandatory. The QDR-II+ interface suits applications requiring deterministic access times. Verify that the 1.8V supply rail matches system power constraints. Consider the 72Mbit capacity relative to memory map requirements.

Application Specific Microcontrollers Part Context

This part belongs to the Infineon QDR-II+ family of synchronous SRAMs. It is specifically engineered for harsh environments where standard commercial parts would fail. The 'W' prefix typically denotes a wide temperature range or specific qualification level within the product line.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes must match the 72Mbit density, QDR-II+ protocol, and radiation hardness. Check for equivalent military-grade packages. Generic QDR SRAMs without RH qualification are not suitable replacements.
