7026L20JGI

Memory IC Overview

The Renesas Electronics Corporation 7026L20JGI is a high-speed dual-port static random access memory (SRAM) with a storage capacity of 256 kbit, organized as 16 k x 16. It features an asynchronous parallel interface and operates within a supply voltage range of 4.5 V to 5.5 V. The component has a maximum access time of 20 ns and supports a data rate of 32 bits. It is designed for surface mount installation in a PLCC-84 package. The device functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to the same memory location by two separate ports.
• Integrated on-chip hardware support for semaphore signaling and port arbitration logic to manage concurrent bus access.
• Separate upper-byte and lower-byte control lines provide compatibility with multiplexed bus systems.
• Automatic power-down feature controlled by chip enable signals allows entry into low standby power mode.

Memory IC Applications

• Stand-alone dual-port RAM implementations
• Master/Slave dual-port RAM configurations for 32-bit or wider word systems
• High-speed data buffering in embedded processing systems

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity and moisture sensitivity handling requirements before assembly. Check for specific RoHS compliance documentation as indicated in official specifications. Ensure replacement sourcing aligns with long-term availability constraints.

Memory IC Selection Notes

Select this component when simultaneous bidirectional memory access is required without external arbitration overhead. The 20 ns access speed suits high-performance asynchronous applications. Verify that the PLCC-84 footprint matches the target PCB design. Consider the 5V TTL-compatible I/O levels for direct interfacing with standard logic families.

Memory IC Part Context

This part belongs to the Renesas 7026L series of dual-port SRAMs. It shares architectural similarities with other members like the 7026L35J but offers faster 20 ns performance. The series is characterized by its ability to function as either standalone or master/slave units, providing flexibility in system memory design.

Memory IC Replacement Considerations

IDT7026L20JGI is a confirmed substitute part number.
