71V65603S150BG

Overview

The 71V65603S150BG is a synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics Corporation. It provides a storage capacity of 9 Megabits organized as 256K words by 36 bits. The device supports a maximum clock frequency of 150 MHz with an access time of 6.7 ns. It operates on a single 3.3V power supply within the range of 3.135V to 3.465V and features a parallel interface. The component is housed in a 165-CABGA package measuring 13x15 mm, designed for surface mount installation.

Feature Summary

• Supports high-speed synchronous operation at 150 MHz with zero bus turnaround capability
• Provides wide 36-bit data organization suitable for processor cache applications
• Operates on a standard single 3.3V power supply voltage

Applications

• Processor secondary cache memory systems
• High-performance embedded controller data storage
• Network equipment buffer memory

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against specific project standards, as legacy variants may differ. Validate package dimensions and pinout compatibility during integration planning. Review official product change notices for any manufacturing site or labeling updates prior to procurement.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required for system architecture. Ensure the design accommodates the 165-CABGA package footprint and thermal characteristics. Verify that the 150 MHz clock speed meets the target application timing constraints. Consider alternative packages if different form factors are needed within the same family.

Part Context

This part belongs to the 71V65603 series of synchronous SRAMs from Renesas. The series offers various speed grades and package options including TQFP, BGA, and CABGA configurations. All variants share the same 9Mb memory organization but differ in access times and physical dimensions to suit diverse board space and performance requirements.

Replacement Considerations

Official substitutes include the 71V65703S80PFGI and IS61NLP25636A-200TQLI. Verify electrical compatibility and pin alignment before substitution.
