Procurement Notes
Verify the End-of-Life status before procurement, as the manufacturer indicates this product is obsolete and will be discontinued. Confirm availability through authorized distributors, noting that stock may be limited or restricted in certain regions. Ensure compliance with RoHS specifications and moisture sensitivity levels during handling and storage to maintain component integrity.
Selection Notes
Select this component when a 128 k x 36 organization is required with synchronous ZBT SRAM performance at 133 MHz. Consider the CABGA-165 package constraints and the specific 3.3V I/O voltage requirements. Evaluate the thermal characteristics within the -40 C to +85 C range against the application environment. Compare against other members of the 71V3556SA series for alternative speed grades or package options if availability is constrained.
Part Context
This part belongs to the Renesas 71V3556SA series of Synchronous ZBT SRAMs. These devices are designed for applications demanding high bandwidth and low latency. The series typically includes variants with different clock speeds and package types, such as the 100 MHz and 166 MHz versions. The SA suffix denotes specific internal characteristics within the broader 71V3556 family.
Replacement Considerations
Publicly confirmed substitute part numbers include IDT71V3556SA133BGGI8 and 71V3556SA133BGGI8. Verify pin compatibility and electrical specifications before substitution.
