71V321L25JG

Overview

The Renesas Electronics 71V321L25JG is a 16Kbit dual-port asynchronous static random-access memory (SRAM) organized as 2K x 8 bits. It features a maximum access time of 25 ns and operates within a supply voltage range of 3 V to 3.6 V. The device supports parallel interface communication and has a maximum power supply current of 100 mA. It is designed for operation in commercial temperature environments, ranging from 0°C to +70°C. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package with J-leads, measuring 19.13 mm by 19.13 mm.

Feature Summary

• Dual-port architecture enabling independent read/write operations on separate ports
• Asynchronous parallel interface for straightforward system integration
• Single 3.3 V power supply operation compatible with standard logic levels

Applications

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

Procurement Notes

Verify the specific suffix 'JG' corresponds to the 52-PLCC package and commercial temperature range during procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity aligns with manufacturer minimums if applicable. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a compact dual-port SRAM solution is required for space-constrained designs. The 52-PLCC package offers a suitable footprint for through-hole or surface-mount assembly depending on board design. Consider the 25 ns access speed against system timing requirements. Evaluate the 16 Kbit capacity against total memory needs to avoid over-specification.

Part Context

This part belongs to the Renesas 71V321L series of low-power dual-port SRAMs. The series provides flexible memory solutions for various digital signal processing and control applications. The 'L' designation typically indicates low-power characteristics within the product family. This specific model represents an older generation PLCC package option compared to modern TQFP alternatives.

Replacement Considerations

The IDT71V321L25JG is a direct functional equivalent from Integrated Device Technology. Verify pin-to-pin compatibility before substitution. Other package variants such as TQFP versions require adapter considerations or PCB redesign.
