71V321L55PF8

Overview

The 71V321L55PF8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a storage capacity of 16 kilobits, organized as 2048 words by 8 bits. The device operates with an asynchronous parallel interface and features a maximum access time of 55 nanoseconds. It supports a supply voltage range from 3.0 volts to 3.6 volts. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 millimeters. It is designed for surface-mount installation and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for straightforward integration into standard logic systems
• Single data rate operation supporting high-speed data transfer capabilities

Applications

• Data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• FIFO buffer applications in industrial control networks

Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm package type and pinout compatibility. Confirm RoHS compliance status as historical records indicate non-compliance for certain variants. Check current production status as this component may be discontinued or subject to limited availability. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a dual-port SRAM solution is required for systems needing concurrent access from two distinct masters. Compare the 55 ns access time against system timing requirements to ensure adequate performance margins. Evaluate the 64-TQFP package constraints against available printed circuit board real estate. Consider power consumption specifications relative to thermal management capabilities in the target enclosure.

Part Context

This part belongs to the 71V321L series of dual-port SRAMs from Renesas Electronics. The series typically offers various speed grades and package options to suit different design needs. The 'L' designation generally indicates low-voltage operation compatible with 3.3V logic levels. This specific model represents one of the slower speed variants within the family, prioritizing cost-effectiveness over ultra-high-speed performance.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific variant were not identified in the provided source material. Verify cross-references with IDT-branded equivalents if applicable, ensuring electrical parameters and pin configurations match exactly.
