71V3577S75BQI

Overview

The IDT71V3577S75BQI is a synchronous single data rate (SDR) static random-access memory integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 4.5Mb, organized as 128K words by 36 bits. The device supports a maximum clock frequency of 117 MHz with an access time of 7.5 ns. It operates on a 3.3V core supply and utilizes parallel interface technology. The component is housed in a 165-pin CABGA package measuring 13x15 mm.

Feature Summary

• Supports burst mode operations offering four cycles of data for a single address to enhance system performance
• Includes self-timed write cycle functionality controlled by global write control and byte write enable signals
• Features low power down mode managed by the ZZ input pin

Applications

• High-performance embedded systems requiring fast data access
• Industrial network solutions utilizing synchronous memory interfaces
• Systems integrating 3.3V I/O logic levels

Procurement Notes

Verify current availability status as this component may be subject to end-of-life notices or discontinuation. Confirm RoHS compliance requirements against specific project standards, noting that some variants in this series have been reported as non-compliant. Ensure the 165-CABGA footprint matches the target PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this part when a 36-bit wide synchronous SRAM interface is required for high-speed data buffering. The 7.5 ns access time suits applications demanding operation at frequencies up to 117 MHz. Consider the 165-pin BGA package size for board space limitations. Verify that the system voltage aligns with the specified 3.135V to 3.465V range for reliable operation.

Part Context

This component belongs to the 71V3577 family of synchronous SRAMs from Renesas. The family offers various speed grades and packaging options, including PBGA and TQFP configurations. The 71V3577S75BQI specifically denotes the 7.5 ns speed grade within the 165-pin CABGA form factor, providing a balance between speed and density for complex digital designs.

Replacement Considerations

Check for direct substitutes such as the IDT71V3577S85BQI for slower speed requirements or different packaging needs. Verify compatibility with existing firmware and timing constraints if swapping between speed grades within the same family.
