71V321L25JG8

Overview

The Renesas Electronics Corporation 71V321L25JG8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kbits, organized as 2K x 8 bits. The device features a parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 3 V to 3.6 V and has a maximum power supply current of 100 mA. The component supports an operating temperature range from -40°C to +85°C and is housed in a 52-PLCC package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array by two separate masters.

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded controllers
• Temporary data storage in telecommunications equipment

Procurement Notes

Verify the specific package type and suffix against official Renesas documentation to ensure compatibility with your design requirements. Confirm RoHS compliance status for the specific manufacturing lot, as regulatory standards may vary by production date. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when independent read/write operations are required on shared memory resources without external arbitration logic. The 25 ns access speed suits moderate-frequency asynchronous applications. Ensure the system voltage aligns with the 3 V to 3.6 V operational range and that the PLCC footprint fits the PCB layout constraints.

Part Context

This device belongs to the 71V321L series of dual-port SRAMs from Renesas Electronics. The series offers various access speeds and package options to accommodate different performance and form-factor requirements in industrial and commercial electronic designs.

Replacement Considerations

Check for direct pin-compatible replacements within the same series, such as variants with different access times or packages, using official Renesas substitution guides.
