71V321L35PFGI8

Overview

The Renesas Electronics Corporation 71V321L35PFGI8 is a dual-port static random access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 35 nanoseconds and a write cycle time of 35 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts. The component is housed in a 64-lead Thin Quad Flat Pack (TQFP) package measuring 14x14 millimeters, designed for surface mount technology. It supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Applications

• Data buffering in high-speed digital signal processing systems.
• Cache memory implementation in embedded microcontroller applications.
• FIFO buffer stages in telecommunications equipment.

Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates potential variations between REACH exemption and specific regional directives. Confirm the exact suffix designation matches the required lead-free specification for your assembly process. Check current production status, as availability may fluctuate due to manufacturing lifecycle changes. Ensure the 64-TQFP footprint aligns with existing PCB designs before finalizing procurement orders.

Selection Notes

Select this component when independent dual-port data handling is required within a compact surface-mount form factor. The 35-nanosecond access speed suits moderate-to-high frequency asynchronous interfaces. Verify that the 3.0V to 3.6V supply range matches the target system's power rails. Consider the 64-pin TQFP package dimensions for thermal management and board space constraints during the design phase.

Part Context

This part belongs to the Renesas 71V321L series of low-voltage dual-port SRAMs. The series provides flexible memory solutions for applications requiring concurrent access. The 'L' designation typically denotes low-voltage operation, while the '35' indicates the access speed class. This specific model represents the industry-standard pinout and electrical characteristics for this memory family.

Replacement Considerations

Direct replacement options include the 71V321L25PFGI8 for faster performance or the 71V321L35JGI for alternative packaging. Verify pin compatibility and electrical specifications before substituting. Consult official manufacturer notices for any recommended upgrades or end-of-life transitions within the product line.
