7026L35G

Memory IC Overview

The Renesas Electronics Corporation 7026L35G is a high-speed Dual-Port Static Random Access Memory (SRAM) with a storage capacity of 256 kbit, organized as 16K x 16. It features an asynchronous parallel interface with a maximum access time of 35 ns. The device operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. Designed for industrial applications, it supports a temperature range from -40°C to +85°C and is available in an 84-pin PLCC package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• On-chip hardware support for semaphore signaling between ports
• Automatic low standby power mode controlled by chip enable signals
• TTL-compatible logic levels for direct system integration

Memory IC Applications

• Stand-alone dual-port memory systems
• Master/Slave configurations for 32-bit or wider data bus expansion
• Industrial control systems requiring isolated port access
• High-performance embedded memory solutions

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm the specific suffix 'G' corresponds to the required lead-free packaging and RoHS compliance status. Check current lifecycle status as this series may be subject to discontinuation notices. Ensure environmental specifications meet the target operating temperature range requirements before procurement.

Memory IC Selection Notes

Select this component when a 16K x 16 density is required with independent dual-port access capabilities. The 35 ns access speed suits moderate-to-high performance asynchronous applications. Verify that the 84-pin PLCC package fits the board layout constraints. Ensure the system design accommodates the 5V supply voltage and TTL-compatible input thresholds for proper signal interfacing.

Memory IC Part Context

The 7026 series represents a family of high-speed dual-port SRAMs designed for versatile memory management. This specific model provides 256 kbit density, balancing capacity with speed. It serves as a foundational component for systems needing concurrent data access without external arbitration logic, supporting both standalone and cascaded master/slave configurations for expanded word widths.

Memory IC Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully. Ensure any replacement maintains the 16K x 16 organization and 35 ns access time. Verify package compatibility and thermal specifications match the original design requirements.
