7026S20J

Memory IC Overview

The Renesas Electronics Corporation 7026S20J is a high-speed, asynchronous dual-port static random access memory (SRAM) device. It features a storage capacity of 144 kilobits organized as 16K words by 9 bits. The component supports parallel interface operations with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is designed for surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package. The device functions reliably across an ambient temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Provides independent read/write access to two ports simultaneously without bus contention
• Integrates automatic power-down circuitry controlled by chip enable signals to minimize standby current consumption
• Supports standalone operation or master/slave configurations for expanded word-length systems

Memory IC Applications

• High-performance data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network routing hardware

Memory IC Procurement Notes

Verify the specific suffix J indicates the 68-PLCC package configuration and commercial temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for end-of-life notifications or obsolescence notices from Renesas Electronics to ensure long-term supply availability for production planning.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required between two processors or controllers. Ensure the system design accommodates the 68-pin PLCC footprint and provides adequate thermal management for the specified operating temperature range. Verify that the 5V logic levels match the host system interfaces.

Memory IC Part Context

This part belongs to the Renesas 7026 series of dual-port SRAMs, which are engineered for applications requiring high bandwidth and low latency. The series offers various access times and organization options to suit different performance requirements in embedded and industrial environments.

Memory IC Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Potential alternatives may include other 7026 series variants with different access speeds or pin-compatible packages, provided functional specifications align.
