Procurement Notes

Verify the specific suffix PFG to confirm the 100-pin TQFP plastic package configuration. Ensure the 7ns speed grade matches system timing requirements. Confirm RoHS compliance status if environmental regulations apply. Check for lead-free soldering compatibility during assembly. Validate that the synchronous interface protocol aligns with the host controller specifications.

Selection Notes

Select this component when a 32-bit wide synchronous SRAM with 7ns access time is required. It is suitable for designs needing 1Mbit capacity with low latency. Consider the 100-pin TQFP footprint for PCB layout constraints. Evaluate thermal dissipation capabilities within the plastic package. Compare against faster or slower variants based on precise clock cycle requirements.

Part Context

This part belongs to the IDT71V432 family of CacheRAM devices. These components are engineered for high-performance computing and communications. The series offers various speed grades and package options. They are widely used in systems requiring fast random access memory for temporary data storage and processing acceleration.

Replacement Considerations

Check for other speed grades within the 71V432S series, such as 71V432S5PFG or 71V432S8PFG, which share the same pinout and organization but differ in access time. Verify functional compatibility before substitution.
