71V321L35PFGI

Overview

The Renesas Electronics Corporation 71V321L35PFGI is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kbit, organized as 2K x 8 bits. The device features an asynchronous parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 3 V to 3.6 V and supports a maximum power supply current of 130 mA. The component is designed for surface mount installation in a 64-TQFP package measuring 14x14 mm. It functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous parallel interface for flexible system integration
• Extended industrial operating temperature range for robust performance

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm the 64-TQFP package and lead-free status. Confirm moisture sensitivity level requirements for your assembly process. Check for product change notices regarding manufacturing site or material updates. Ensure compatibility with your system's voltage levels and timing constraints before finalizing procurement.

Selection Notes

Select this component when a small-capacity, high-speed dual-port memory solution is required. The 35 ns access time suits moderate-speed asynchronous interfaces. Consider the 64-TQFP footprint for board space constraints. Verify that the 3V to 3.6V supply range matches your design's power rails. Compare against other members of the 71V321L series if different speeds or packages are needed.

Part Context

This part belongs to the Renesas 71V321L series of dual-port SRAMs. The series offers various speed grades and packaging options. The 71V321L35 variant specifically denotes the 35 ns access time. Other variants include faster speeds like 25 ns or different package types such as PLCC. This family is designed for applications needing concurrent read/write capabilities.

Replacement Considerations

The IDT71V321L35PFGI is a direct equivalent under the Integrated Device Technology brand, now part of Renesas. Verify pinout and electrical specifications match exactly. Other speed grades in the same package may require timing adjustments.
