71V3559S80PFGI

Overview

The 71V3559S80PFGI is a static random-access memory integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 4 Mbit organized as 256 k x 18 bits. The device utilizes a parallel interface and operates with a supply voltage range of 3.135 V to 3.465 V. Key electrical parameters include an access time of 8 ns and a maximum clock frequency of 100 MHz. It is housed in a TQFP-100 surface-mount package.

Feature Summary

• Supports synchronous single data rate (SDR) operation for high-speed data transfer.
• Features ZBT technology to optimize performance and power consumption.
• Includes dedicated slow output enable pin for flexible system timing control.

Applications

• High-performance embedded systems requiring fast memory access.
• Industrial equipment with real-time processing demands.
• Network infrastructure components utilizing parallel SRAM interfaces.

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity level handling procedures during assembly. Validate package dimensions against PCB footprint specifications before integration.

Selection Notes

Select this component when a 256K x 18 organization is required with 8 ns access speed. Ensure the design supports 3.3V I/O levels and synchronous clocking up to 100 MHz. Consider the TQFP-100 package constraints for board layout. Evaluate alternatives if lead-free or RoHS-compliant versions are mandatory for the target market.

Part Context

This part belongs to the 71V3559 series of synchronous ZBT SRAMs from Renesas. It shares architectural similarities with other variants like the 71V3559S85BQ but differs in package type and specific timing characteristics. The series is designed for applications needing high-density, high-speed volatile memory solutions.
