71V321S35J8

Memory IC Overview

The Renesas Electronics Corporation 71V321S35J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device operates with an asynchronous parallel interface and features a maximum access time of 35 nanoseconds. It functions within a supply voltage range of 3 volts to 3.6 volts. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package, measuring 19.13mm by 19.13mm. It supports surface mount installation and operates at temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.
• Asynchronous parallel interface for straightforward integration into digital systems.
• CMOS technology ensuring low power consumption during operation.

Memory IC Applications

• Data buffering in high-speed communication interfaces
• Cache memory implementation in embedded processing systems
• Temporary data storage in industrial control equipment

Memory IC Procurement Notes

Verify the specific suffix J8 confirms the 52-PLCC package and commercial temperature range. Confirm RoHS compliance status as documentation indicates non-compliance. Check current lifecycle status as the part may be discontinued or subject to production change notices. Ensure compatibility with existing board layouts for the PLCC footprint.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. The 35ns speed suits moderate-frequency applications. Verify that the 52-PLCC package fits the assembly constraints. Consider the operating temperature range limits for environmental suitability. Evaluate power requirements against the specified supply voltage window.

Memory IC Part Context

This SRAM belongs to the 71V321S series, which offers various speed grades and package options. The 'S' designation typically denotes standard performance levels within the family. Related variants include different access times and leaded packages like TQFP. The series supports general-purpose memory needs in legacy and modern designs.

Memory IC Replacement Considerations

Publicly confirmed substitute: 71V321L25TFG. This alternative offers improved speed and extended temperature range but requires package adaptation from PLCC to TQFP.
