7026L25GB

Memory IC Overview

The Renesas Electronics Corporation 7026L25GB is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 256 kilobits organized as 16K words by 16 bits. The component supports parallel interface operations with a maximum access time of 25 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The device is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation. It functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent and simultaneous data access from two separate ports without bus contention.
• On-chip hardware semaphore signaling logic facilitates automatic synchronization and arbitration between the two ports.
• Automatic power-down mode controlled by chip enable signals reduces standby power consumption when the device is inactive.
• TTL-compatible inputs and outputs ensure straightforward integration with standard digital logic systems.

Memory IC Applications

• Stand-alone dual-port memory modules in embedded systems requiring concurrent data handling.
• Master/slave configurations for expanding data bus widths to 32 bits or greater in processing architectures.
• High-speed buffering applications in telecommunications equipment and network infrastructure.
• Industrial control systems operating within extended temperature environments.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential legacy status. Confirm RoHS compliance requirements as older variants may not meet current environmental standards. Validate package integrity upon receipt, as PLCC components are sensitive to mechanical stress during handling. Ensure compatibility with existing PCB footprints and thermal management designs before final procurement decisions.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration logic. Consider the 25ns access speed for timing-critical applications. Evaluate the 84-PLCC package constraints against available board space and mounting methods. Compare against other 7026 series variants if different access speeds or temperature ranges are needed for specific operational environments.

Memory IC Part Context

The 7026L25GB belongs to the Renesas 7026 family of high-performance dual-port SRAMs. This series is engineered for applications demanding high throughput and low latency. The L suffix typically denotes the industrial temperature grade (-40°C to +85°C). The GB suffix indicates the specific package type and pin configuration. This family serves as a foundational memory solution for complex digital signal processing and communication protocols.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for the 7026L25GB were not identified in the provided source material. Users should consult official manufacturer documentation for qualified alternatives or cross-reference with similar dual-port SRAM families such as the 7025 series, ensuring functional and electrical parameter alignment.
