7005L25J8

Overview

The Renesas Electronics Corporation 7005L25J8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kbit organized as 8k x 8 bits. The device supports parallel interface operations with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 210 mA. The component is designed for surface mount installation in a 68-PLCC package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on both ports
• Asynchronous operation without requiring external clock signals
• Parallel data interface for direct connection to system buses

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify the specific suffix J8 confirms the 68-PLCC package type and RoHS status before ordering. Confirm availability as the product may be discontinued or subject to limited stock. Ensure the 4.5V to 5.5V voltage requirement matches the target system design. Check for moisture sensitivity level requirements during handling and storage.

Selection Notes

Select this component when dual independent port access is required for concurrent data processing. The 25 ns speed suits moderate-to-high frequency asynchronous applications. Ensure the PCB layout accommodates the 68-PLCC footprint. Verify that the 210 mA current draw fits within the system's power budget constraints.

Part Context

This part belongs to the Renesas 7005L series of dual-port SRAMs. It shares architectural similarities with other variants like the 7005S25J8 but differs in package and specific electrical characteristics. The series is designed for applications needing fast, non-blocking memory access between two distinct masters.

Replacement Considerations

Check for direct pin-compatible replacements such as the IDT7005L25J8. Verify equivalent speed grades and voltage ranges when substituting. Ensure the replacement maintains the 68-PLCC form factor if board space is constrained.
