7005L15J

Overview

The Renesas Electronics Corporation 7005L15J is a dual-port static random-access memory (SRAM) device with a storage capacity of 64 kbit, organized as 8k x 8. It features an asynchronous parallel interface with a maximum access time of 15 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 210 mA. It supports surface-mount installation in a 68-PLCC package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent read/write operations on two ports
• Asynchronous parallel interface for flexible system integration
• High-speed data access with 15 ns maximum access time

Applications

• Data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO applications requiring dual-port capability

Procurement Notes

Verify the exact suffix designation for the specific package variant required, as the base model number may correspond to multiple packaging options such as PLCC or TQFP. Confirm RoHS compliance status and moisture sensitivity level prior to ordering, as these attributes vary by manufacturing lot and specific sub-part number. Check for end-of-life notifications or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a dual-port SRAM solution is required for high-speed data buffering between asynchronous logic blocks. Ensure the system design accommodates the 4.5 V to 5.5 V supply voltage range and the 68-pin PLCC footprint. Consider the 15 ns access time against system timing requirements and verify that the 210 mA maximum current draw fits within the power budget constraints of the application environment.

Part Context

This part belongs to the Renesas 7005L series of dual-port SRAMs, which are designed for applications requiring simultaneous access from two different masters. The series offers various speed grades and package options to suit different performance and form factor needs. The 7005L15J specifically targets systems needing fast, reliable memory with independent port control.

Replacement Considerations

Potential substitutes include other 64Kb dual-port SRAMs with similar 15 ns access times and 5V operation, such as the IDT7005L15J or compatible parts from other manufacturers offering pin-compatible alternatives in 68-PLCC packages.
