71V67903S75PFGI

Memory IC Overview

The IDT71V67903S75PFGI is a 9 Mbit Synchronous Single Data Rate (SDR) Static Random Access Memory (SRAM) manufactured by Renesas Electronics. It features a memory organization of 512K x 18 bits and supports parallel interface communication. The device operates with an access time of 7.5 ns and a maximum clock frequency of 117 MHz. Power supply requirements range from 3.135 V to 3.465 V, with a maximum power current of 285 mA. It is housed in a 100-TQFP surface-mount package and functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports burst counter flow-through outputs for sequential data access.
• Enables single cycle deselect for flexible control over memory operations.
• Utilizes 3.3V I/O levels compatible with standard logic families.

Memory IC Applications

• High-speed cache memory systems
• Network routing equipment buffers
• Industrial control system data storage

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance and moisture sensitivity level (MSL 3) handling requirements during assembly. Cross-reference datasheet revisions to ensure pinout and electrical characteristics match the specific manufacturing lot before integration into final designs.

Memory IC Selection Notes

Select this component when a 9 Mbit synchronous SRAM with 7.5 ns speed is required in a 100-pin TQFP package. Ensure the design accommodates the 3.3V I/O voltage levels and 285 mA maximum current draw. Consider alternative packages if space constraints differ from the 14x14 mm footprint.

Memory IC Part Context

This part belongs to the 71V67903 series of 3.3V Synchronous SRAMs. It shares architectural similarities with other variants like the 71V67703 but differs in memory organization (512K x 18 vs 256K x 36). The series is designed for high-performance applications requiring fast random access and burst capabilities.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers include IS61LF51218A-7.5TQLI from ISSI. Verify functional compatibility and pin alignment before substitution.
