71321LA25JGI

Memory IC Overview

The Renesas Electronics Corporation 71321LA25JGI is a dual-port static random-access memory (SRAM) device. It features a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The component supports asynchronous parallel interface operations with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package. The device is designed for surface-mount installation and supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

Memory IC Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations exist within the 71321LA series. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary based on production lifecycle stages. Ensure the specific package type matches design requirements before ordering.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Compare access speeds and power consumption against single-port alternatives if only one master is needed. Verify that the 52-PLCC package dimensions fit the printed circuit board layout constraints. Consider thermal management requirements given the operating temperature range and power dissipation specifications.

Memory IC Part Context

This part belongs to the Renesas 71321LA family of high-speed dual-port SRAMs. These devices are engineered for applications demanding fast data transfer rates and independent port access. The LA suffix typically denotes specific speed grades and package configurations within the broader product line, distinguishing it from other variants like the SA series or different pin counts.

Memory IC Replacement Considerations

Check for direct cross-references such as IDT71321LA25JGI. Evaluate alternative dual-port SRAMs with compatible pinouts and electrical specifications if the original part is discontinued. Ensure functional equivalence regarding access times and voltage levels before substitution.
