7008L20JGI

Memory IC Overview

The Renesas Electronics Corporation 7008L20JGI is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a total storage capacity of 512 kilobits, organized as 64K words by 8 bits. The component features true dual-ported memory cells that allow simultaneous independent reads and writes from either port without conflict. It operates with a TTL-compatible single 5V power supply within a voltage range of 4.5V to 5.5V. The device supports an access time of 20 nanoseconds and includes on-chip hardware support for semaphore signaling and port arbitration logic. It is housed in an 84-pin PLCC package.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location from both ports.
• On-chip hardware support for semaphore signaling and automatic port arbitration logic to manage bus conflicts.
• Automatic power-down feature controlled by chip enable signals to achieve very low standby power modes.
• TTL-compatible interface allowing direct connection to standard digital logic systems.

Memory IC Applications

• Stand-alone 512k-bit dual-port memory systems
• Master/slave dual-port configurations for 16-bit or wider data bus systems
• Battery-backed operation requiring 2V data retention capabilities

Memory IC Procurement Notes

Verify current availability status as this component may be subject to end-of-life notices or limited production runs. Confirm RoHS compliance specifications against the latest manufacturer documentation before integration. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate pinout compatibility with existing PCB layouts during the design phase.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration overhead. Suitable for applications needing fast parallel interface speeds with low standby power consumption. Consider the 84-pin PLCC package constraints for board space and thermal management requirements.

Memory IC Part Context

This part belongs to the 7008L series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other variants in the family but differs in specific speed grades and packaging options. The 7008L20 designation indicates a 20ns access time variant within this product line.

Memory IC Replacement Considerations

Check for official substitute part numbers provided by Renesas Electronics if this specific package or speed grade is unavailable. Verify functional equivalence regarding pinouts and electrical characteristics before substitution.
