7026L20G

Memory IC Overview

The Renesas Electronics Corporation 7026L20G is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 256 kilobits. The device features a memory organization of 16K words by 16 bits and supports parallel interface communication. It operates within a supply voltage range of 4.5V to 5.5V and provides an access time of 20 nanoseconds. The component is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation. It functions reliably across a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems without bus contention.
• Asynchronous operation allowing flexible timing integration into various digital logic environments.
• Automatic power-down mode controlled by chip enable signals to reduce standby power consumption.

Memory IC Applications

• Stand-alone dual-port RAM modules in embedded systems
• Master/slave dual-port configurations for 32-bit or wider data word processing
• High-speed buffering applications requiring concurrent read/write operations

Memory IC Procurement Notes

Verify the specific suffix 'G' against official manufacturer documentation to confirm lead-free compliance status. Confirm that the PLCC-84 package dimensions match the target PCB footprint requirements. Check current product lifecycle status as this series may be subject to discontinuation notices. Ensure voltage levels align with system specifications before integration.

Memory IC Selection Notes

Select this component when a 256Kb capacity with 16-bit word width is required for asynchronous dual-port applications. The 20ns access speed suits moderate-to-high performance data buffering needs. Consider the 84-PLCC package constraints for board space and thermal management. Verify compatibility with 5V logic families used in the target design environment.

Memory IC Part Context

This part belongs to the 7026L family of dual-port SRAMs manufactured by Renesas Electronics. These devices are engineered for applications demanding high-density memory with concurrent access capabilities. The family typically includes variants with different access speeds and packaging options to support diverse industrial and commercial electronic designs.

Memory IC Replacement Considerations

Consult official substitution guides for equivalent dual-port SRAMs with matching 256Kb density and 16-bit width. Verify pinout compatibility if replacing with similar packages. Cross-reference electrical specifications such as voltage ranges and access times to ensure functional parity in the existing circuit design.
