7026L12J8

Memory IC Overview

The Renesas Electronics Corporation 7026L12J8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 256K bits organized as 16K words by 16 bits. The device features parallel interface access with a maximum access time of 12 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-PLCC package measuring 29.31x29.31 mm. The component functions as a standalone dual-port RAM for data storage applications.

Memory IC Feature Summary

• Supports simultaneous independent access from two ports for concurrent read/write operations
• Provides high-speed asynchronous data transfer capabilities
• Utilizes CMOS technology for efficient power consumption

Memory IC Applications

• Stand-alone dual-port memory systems
• High-speed data buffering in communication equipment
• Cache memory implementations in embedded processing architectures

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the product may not meet current environmental standards. Validate package integrity upon receipt to ensure pin alignment matches the 84-PLCC specification. Review official datasheets for updated handling instructions regarding moisture sensitivity level 3.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without bus contention. Ensure system timing constraints align with the 12 ns access speed. Verify that the 84-pin PLCC footprint fits the target PCB layout. Confirm voltage compatibility with the 4.5V to 5.5V operating range before integration into the design.

Memory IC Part Context

This part belongs to the IDT7026 series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other variants in the family but differs in access speed specifications. The series is designed for applications requiring high-performance memory sharing between multiple processors or controllers.

Memory IC Replacement Considerations

Official substitute part numbers are not explicitly documented in the provided source material. Evaluate alternative dual-port SRAMs with compatible 16K x 16 organization and similar access speeds. Verify pin-to-pin compatibility with the 84-PLCC package before substitution.
