71321LA35J8

Memory IC Overview

The Renesas Electronics Corporation 71321LA35J8 is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits, organized as 2K by 8 bits. The device utilizes asynchronous parallel interface technology with an access time of 35 nanoseconds. It operates within a supply voltage range of 4.5 to 5.5 volts and supports surface-mount installation in a 64-TQFP package. The component is designed for commercial temperature environments ranging from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location from two separate ports.
• Asynchronous operation requiring no external clock signals or periodic refresh cycles for data retention.
• Integrated port arbitration logic to manage concurrent read and write operations between ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid sequential writes

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as indicated on official documentation. Check moisture sensitivity level handling requirements before assembly. Validate package marking against datasheet specifications. Ensure supply chain stability given end-of-life status.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Compare access times and power consumption against alternative SRAM families. Verify package compatibility with existing PCB footprints. Consider thermal performance within specified operating temperature ranges. Evaluate system integration complexity relative to single-port alternatives.

Memory IC Part Context

This part belongs to the 71321SA/LA series of dual-port SRAMs manufactured by Renesas Electronics. It succeeds earlier IDT-branded variants following corporate acquisitions. The 71321LA35J8 represents a specific speed grade and package configuration within this product line. It shares architectural similarities with other members of the 7132 family but differs in pinout and electrical characteristics.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers include IDT71321LA35J8. Cross-reference pinouts and electrical parameters before substitution. Verify package dimensions match existing board layouts. Confirm functional equivalence regarding port arbitration logic.
