7025L12J

Memory IC Overview

The Renesas Electronics Corporation 7025L12J is a dual-port static random-access memory (SRAM) integrated circuit. It features an asynchronous parallel interface with a storage capacity of 128 kbit, organized as 8K words by 16 bits. The device supports a maximum access time of 12 ns and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in an 84-PLCC package with dimensions of 29.31 x 29.31 mm. The component is designed for surface-mount installation and functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on two separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data storage in industrial control applications

Memory IC Procurement Notes

Verify the current lifecycle status before procurement, as this component may be discontinued or subject to production end-of-life notifications. Confirm that the 84-PLCC package dimensions match the target PCB footprint. Ensure the selected variant meets the required RoHS compliance standards for the intended market. Check for any specific humidity sensitivity level requirements during storage and handling.

Memory IC Selection Notes

Select this component when a dual-port SRAM solution is required for applications needing concurrent access from two distinct masters. The 12 ns access speed suits moderate-to-high frequency asynchronous interfaces. Consider the 84-PLCC package constraints for board space and thermal management. Verify that the 4.5 V to 5.5 V operating voltage aligns with the system power rails.

Memory IC Part Context

This part belongs to the Renesas 7025L series of dual-port SRAMs. It shares architectural similarities with other members like the 7025L15JG8 and 7025L20JGI8, differing primarily in access speed and package type. The series provides non-volatile-like performance through volatile memory technology optimized for high-speed data transfer between asynchronous domains.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative dual-port SRAMs with compatible pinouts and electrical specifications if direct replacements are unavailable.
