71V3559S80BG

Overview

The IDT71V3559S80BG is a 4.5Mb Synchronous ZBT SRAM organized as 256K x 18, manufactured by Renesas Electronics Corporation. It features an 8 ns access time and operates on a parallel interface with a supply voltage range of 3.135V to 3.465V. The device is housed in a 119-PBGA package measuring 14x22 mm, designed for surface mount installation. It supports a commercial operating temperature range of 0°C to 70°C and utilizes CMOS technology.

Feature Summary

• Synchronous Zero-Bus-Zap (ZBT) architecture for high-speed data transfer
• Parallel memory interface supporting standard synchronous protocols
• CMOS technology ensuring low power consumption during operation

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing synchronous logic
• Industrial control systems operating within commercial temperature ranges

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Validate package dimensions against PCB footprint specifications before integration into new designs.

Selection Notes

Select this component for applications requiring 4.5Mb capacity with 8 ns latency. Ensure system voltage aligns with the 3.135V to 3.465V specification. Consider the 119-PBGA package constraints for thermal management and board space allocation in dense layouts.

Part Context

Part of the IDT71V3559 family of synchronous ZBT SRAMs. Shares architectural similarities with variants like IDT71V3559SA80BQGI8 but differs in package type and temperature rating. Designed for legacy systems transitioning from asynchronous memories to synchronous solutions.

Replacement Considerations

IDT71V3559SA80BQGI8 offers similar electrical characteristics but uses a 165-CABGA package and extended temperature range. Verify pin compatibility and physical dimensions before substitution.
