Memory IC Procurement Notes

Verify the current lifecycle status before procurement as this component may be subject to discontinuation or obsolescence notices. Confirm that the 208-lead CABGA package dimensions align with existing PCB footprints. Ensure design compatibility with 2.5V core voltage requirements and 3.3V I/O levels. Check for specific moisture sensitivity level constraints during assembly processing. Validate that the lead-free status meets regulatory standards for the target market.

Memory IC Selection Notes

Select this component when a synchronous dual-port SRAM with 36-bit word width is required for complex data structures. Consider the 133 MHz operating frequency for applications needing rapid data exchange between multiple processors. Evaluate the 208-lead CABGA package for suitable thermal and spatial constraints on the circuit board. Compare power consumption characteristics against other members of the 70T3589 series if lower power variants are needed.

Memory IC Part Context

This part belongs to the 70T3589 series of synchronous dual-port RAMs from Renesas Electronics. It shares architectural similarities with related models such as the 70T3599 and 70T3519, differing primarily in memory density and pin configurations. The series is designed for applications requiring high-speed, non-volatile-like performance without the complexity of flash memory controllers.

Memory IC Replacement Considerations

Direct substitutes include other parts within the 70T3589 family, such as the 70T3589S133BFI8, which offers identical electrical specifications but may differ in packaging format. Verify pin-to-pin compatibility and functional equivalence before replacing the component in existing designs.
