71V321L35JGI8

Memory IC Overview

The Renesas Electronics Corporation 71V321L35JGI8 is a 16Kbit (2K x 8) dual-port static random-access memory (SRAM). It operates on a single 3.0V to 3.6V power supply with a maximum current consumption of 130 mA. The device features asynchronous parallel interfaces and supports access times of 35 ns. It is housed in a 52-PLCC package with J-leads, measuring 19.13x19.13 mm. The component is designed for surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location from two separate ports.
• On-chip port arbitration logic manages concurrent read/write operations without external control.
• Interrupt flags facilitate direct communication between the two ports for status monitoring.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Network switch and router packet storage
• Industrial automation controller memory

Memory IC Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm moisture sensitivity level (MSL 3) requirements for handling. Check for End-of-Life notifications or Product Change Notices affecting availability. Ensure packaging type matches design specifications.

Memory IC Selection Notes

Select this component for designs requiring true dual-port SRAM with independent asynchronous access. Verify voltage compatibility with 3.3V systems. Consider package constraints for 52-PLCC footprint. Evaluate thermal performance within the specified industrial temperature range.

Memory IC Part Context

Part of the 71V321L series, which includes variants like 71V321L35J8 and 71V321L35PFGI8. These devices share similar electrical characteristics but differ in package types such as PLCC, TQFP, and lead counts. The series targets high-performance memory applications requiring fast access times.

Memory IC Replacement Considerations

IDT71V321L35JGI8 is listed as an alias part number. Verify pinout and electrical specifications match before substitution. Other series members may require package adaptation.
