7005L20JGI8

Overview

The 7005L20JGI8 is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 20 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in a surface-mount 68-pin Plastic Leadless Chip Carrier (PLCC) package, measuring 24.21mm by 24.21mm. It supports an industrial operating temperature range from 0°C to +70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent read and write operations from two distinct ports without conflict.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between the two ports.
• Automatic power-down feature controlled by chip enable signals to reduce standby power consumption during inactive periods.

Applications

• High-speed data buffering in telecommunications equipment requiring low-latency memory access.
• Master/slave dual-port configurations in 16-bit or wider data bus systems.
• Industrial control systems requiring reliable volatile memory with interrupt flag capabilities.

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level handling requirements before assembly. Check for valid datasheet revisions and ensure compatibility with existing PCB footprints. Validate that the specific suffix matches required packaging and temperature grades.

Selection Notes

Select this component when true dual-port functionality is required for concurrent host and peripheral access. Ensure system design accommodates the 68-pin PLCC footprint and 5V logic levels. Consider the 20ns access speed against system timing constraints. Verify that the commercial temperature range meets environmental specifications.

Part Context

This part belongs to the Renesas 7005 series of high-speed dual-port SRAMs. The series offers various access speeds and package options to suit different performance and form factor requirements. The 7005L20 variant specifically targets applications needing 20ns speed in a compact PLCC package.

Replacement Considerations

Consult official Renesas documentation for qualified substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference with equivalent offerings from other manufacturers only if fully documented.
