Procurement Notes

Verify current manufacturing status as the part may be obsolete or subject to production changes. Confirm moisture sensitivity level handling requirements during assembly. Ensure the specific suffix PFG8 matches the required package variant. Check for official product change notices regarding pinout or electrical parameter updates before finalizing design-in decisions.

Selection Notes

Select this component when a synchronous SRAM with 36-bit word width is required for wide-data bus applications. Compare against asynchronous alternatives if lower power consumption at idle states is critical. Verify that the 100-pin TQFP footprint fits the available board space constraints. Ensure the system clock can support the 133 MHz operational frequency for optimal throughput.

Part Context

This device belongs to the 71V547 series of synchronous SRAMs from Renesas. The series is characterized by zero wait-state operation and low power consumption modes. It serves as a high-speed memory solution for embedded systems requiring rapid data access. The 71V547 family offers various speed grades and package options to accommodate different performance and form factor requirements.

Replacement Considerations

The 71V547S100PFGI8 is listed as a similar replacement option. Verify timing compatibility as the substitute may have different access specifications. Ensure the package dimensions and pin assignments remain identical to avoid mechanical redesign.
