71V3557S80PFG8

Overview

The Renesas 71V3557S80PFG8 is a 4.5Mb (128K x 36) synchronous ZBT SRAM in a 100-pin TQFP package. It features an 8 ns access time and supports clock frequencies up to 100 MHz. The device operates on a 3.3V core supply with 3.3V I/O, functioning within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports high-speed parallel data transfer via synchronous ZBT architecture
• Provides fast access times for efficient system performance
• Operates with standard 3.3V power supplies

Applications

• High-performance embedded systems requiring fast memory access
• Network infrastructure equipment
• Industrial control applications

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details as specifications may vary by production batch. Ensure the 100-TQFP package matches PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this part for designs needing 36-bit wide synchronous memory interfaces. Verify that the 8 ns speed meets timing constraints. Consider the 100-pin TQFP form factor for board layout compatibility. Check if industrial temperature grades are required for specific environmental conditions.

Part Context

This component belongs to the 71V3557 family of synchronous SRAMs. It shares architectural similarities with other devices in the series but differs in speed grade and packaging options. The suffix indicates specific pinout and package characteristics.

Replacement Considerations

Check for IS61NLF12836A-7.5TQLI from ISSI as a potential alternative. Verify electrical compatibility and pin assignments before substitution.
