7005L15JG8

Overview

The Renesas Electronics Corporation 7005L15JG8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It features a storage capacity of 64K bits organized as 8K words by 8 bits. The device operates with a 15 nanosecond access time and supports parallel interface communication. It functions 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 24.0 x 24.0 mm. It is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from the same memory location by both ports.
• Integrated hardware support for semaphore signaling and port arbitration logic to manage data access conflicts.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.
• TTL-compatible inputs and outputs allowing direct interfacing with standard digital logic systems.

Applications

• Stand-alone 64K-bit dual-port RAM modules
• Master/Slave dual-port configurations for 16-bit or wider word systems
• High-speed data buffering in embedded processing systems

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS3 compliance and moisture sensitivity level 3 handling requirements during assembly. Check for specific manufacturing date codes if long-term reliability is critical. Ensure packaging integrity matches reel specifications to prevent lead damage.

Selection Notes

Select this part when true dual-port simultaneous access is required for 8-bit wide data paths. Compare against 7005L45 variants if slower speeds suffice, or 7007L15 models for higher density needs. Verify that the 68-pin PLCC footprint aligns with existing PCB layouts. Consider battery backup capabilities for data retention requirements.

Part Context

This component belongs to the IDT 7005 family of dual-port SRAMs, now manufactured under Renesas Electronics after acquisition. The family provides non-volatile-like functionality through battery backup options while maintaining high-speed volatile performance. It serves as a bridge between fast processors and slower peripheral devices in complex digital architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The 7005L15JG8 is listed as obsolete. Designers should consult official Renesas replacement guides for pin-compatible alternatives or functional equivalents within the current portfolio.
