7005L15JG

Overview

The Renesas Electronics Corporation 7005L15JG is a high-speed, asynchronous dual-port static random access memory (SRAM) device. It features a storage capacity of 64 kilobits organized as 8K words by 8 bits. The component provides an access time of 15 nanoseconds and operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. It utilizes a parallel interface and is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface mount installation. The device supports industrial temperature ranges and includes hardware support for port arbitration.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from the same memory location by both ports.
• On-chip hardware logic supporting semaphore signaling and automatic interrupt flags for efficient inter-port communication.
• 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
• Battery backup operation requiring data retention

Procurement Notes

Verify RoHS compliance status and moisture sensitivity level prior to ordering. Confirm current availability as this component may be subject to limited supply or obsolescence notices. Ensure the specific suffix matches the required package type and temperature grade. Cross-reference official datasheets for any recent product change notifications affecting pinout or electrical characteristics.

Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration logic. The 15ns speed suits high-performance applications needing fast data exchange between processors. Verify that the 68-pin PLCC package fits the target PCB layout constraints. Consider the 5V supply requirement against system voltage levels.
