7026L25J

Memory IC Overview

The Renesas Electronics Corporation 7026L25J is a dual-port static random access memory (SRAM) device with a storage capacity of 256 kbit, organized as 16K x 16. It features an asynchronous parallel interface and supports a supply voltage range from 4.5 V to 5.5 V. The component has a maximum access time of 25 ns and operates within a temperature range of 0°C to +70°C. It is housed in an 84-pin PLCC package designed for surface mount installation.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Automatic power-down mode controlled by chip enable signals
• Asynchronous parallel interface for flexible system integration

Memory IC Applications

• Stand-alone dual-port RAM systems
• Master/Slave dual-port RAM configurations for 32-bit or wider word systems
• High-speed data buffering between asynchronous logic blocks

Memory IC Procurement Notes

Verify the current lifecycle status before procurement, as this component may be discontinued. Confirm that the RoHS compliance status aligns with project requirements, noting potential variations based on manufacturing date. Ensure the 84-PLCC package dimensions match the target PCB footprint. Validate that the 4.5V to 5.5V operating voltage is compatible with the system power rails. Check for any specific humidity sensitivity level handling requirements during storage and assembly.

Memory IC Selection Notes

Select this component when a high-density dual-port SRAM solution is required for applications needing independent read/write access from two distinct masters. The 25 ns access time suits moderate-speed asynchronous interfaces. Consider the 84-PLCC package constraints for board space. Evaluate if the commercial temperature range meets environmental needs. Compare against other members of the 7026 series for different speed grades or pinouts.

Memory IC Part Context

The 7026L25J belongs to the Renesas 7026 family of high-speed dual-port SRAMs. This family is designed for versatile memory applications requiring concurrent access capabilities. The 'L' suffix typically denotes specific speed or package variants within the broader product line. These devices are engineered to support complex data processing tasks where multiple controllers must interact with shared memory resources efficiently.

Memory IC Replacement Considerations

Check for official manufacturer-recommended substitutes such as the 70V657S12BCGI. Verify pin compatibility and electrical specifications before substitution. Note that alternative parts may differ in access time or package type.
