7006L15JI

Overview

The Renesas Electronics Corporation 7006L15JI is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 128 kilobits. The device features a memory organization of 16K words by 8 bits and supports simultaneous independent access from two ports. It operates within a supply voltage range of 4.5V to 5.5V and provides an access time of 15 nanoseconds. The component is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package with dimensions of 24.21mm x 24.21mm. It is designed for industrial temperature ranges spanning from -40°C to +85°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous reads and writes from both ports without conflict.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity.
• Integrated interrupt flag functionality to signal status conditions between the master and slave ports.
• Automatic power-down feature controlled by chip enable inputs to minimize standby power consumption.

Applications

• Multiprocessing systems requiring shared memory resources between multiple processors.
• Master/Slave dual-port configurations for expanding data bus widths to 16 bits or more.
• Real-time data buffering and rate matching in communication interfaces.
• Industrial control systems operating under extended temperature conditions.

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm that the procurement channel sources components directly from authorized distributors to ensure authenticity. Check for any product change notices regarding packaging or material composition updates. Ensure the supplier can provide traceability documentation required for industrial applications.

Selection Notes

Select this component when a system requires true dual-port capability with independent address and data buses for each port. The 15ns access speed suits high-throughput applications where low latency is critical. Consider the 68-pin PLCC package constraints for PCB layout and thermal management. Verify that the 5V TTL-compatible I/O levels match the interface requirements of the connected microprocessors or controllers.

Part Context
