7026S20G

Memory IC Overview

The Renesas Electronics Corporation 7026S20G is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 128 kilobits organized as 8K words by 16 bits. The device utilizes a parallel interface with a maximum access time of 20 nanoseconds and operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. It is housed in an 84-pin plastic leaded chip carrier (PLCC) package designed for surface-mount installation. The component supports commercial operating temperatures ranging from 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports via true dual-ported memory cells.
• Includes on-chip hardware support for semaphore signaling to facilitate data synchronization between ports.
• Features automatic power-down functionality controlled by chip enable inputs to minimize standby power consumption.
• Provides separate upper-byte and lower-byte control signals to ensure compatibility with multiplexed bus architectures.

Memory IC Applications

• Stand-alone dual-port RAM configurations
• Master/Slave dual-port RAM combinations for 32-bit or wider word systems
• High-performance embedded memory systems requiring concurrent data access

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental directives. Validate package integrity upon receipt to ensure pin alignment matches the 84-PLCC specification before integration into assembly processes.

Memory IC Selection Notes

Select this component when concurrent read/write operations are required without external arbitration logic. Ensure system design accommodates the 8Kx16 organization and 20ns access speed. Verify that the 84-pin PLCC footprint aligns with existing PCB layouts and that thermal management supports the commercial temperature range limits.

Memory IC Part Context

This part belongs to the 7026 series of high-speed dual-port SRAMs manufactured by Renesas Electronics. The series is engineered for applications demanding fast, independent access from multiple processors or controllers. The 'S' suffix typically denotes the commercial temperature grade, distinguishing it from industrial variants.
