71V321L25PFGI

Overview

The Renesas Electronics Corporation 71V321L25PFGI is a static random-access memory component featuring a storage capacity of 16 kbit organized as 2K x 8. It operates with an asynchronous parallel interface and supports a supply voltage range from 3 V to 3.6 V. The device specifies a maximum access time of 25 ns and a maximum power supply current of 100 mA. It is housed in a TQFP-64 surface-mount package and is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations at two separate ports.

Applications

• Data buffering in high-speed digital signal processing systems.

Procurement Notes

Verify the specific suffix 'PFGI' against the manufacturer's official datasheet to confirm pinout compatibility, RoHS status, and moisture sensitivity level. Ensure the selected variant matches the required industrial temperature grade (-40°C to +85°C) and package dimensions for your PCB layout. Cross-reference ordering information directly with Renesas Electronics documentation to avoid discrepancies.

Selection Notes

Select this component when a dual-port SRAM solution is required for applications needing concurrent data access from two distinct masters. The 25 ns access speed and 3.3 V operation make it suitable for general-purpose embedded systems. Verify that the TQFP-64 package fits the available board space and thermal requirements compared to single-port alternatives or different speed grades within the same family.

Part Context

This part belongs to the 71V321L series of asynchronous dual-port SRAMs manufactured by Renesas Electronics. The series provides non-volatile-like flexibility with volatile memory speeds, designed for applications requiring high throughput and low latency. The 'L' designation typically indicates low-power characteristics within the product line, while the '25' denotes the 25 ns speed grade.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available source material. Consult the manufacturer's official replacement guide or PCN documents for verified cross-references.
