7005S12J8

Overview

The Renesas Electronics Corporation 7005S12J8 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 12 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 290 mA. It supports single data rate (SDR) operation and functions within a temperature range of 0°C to +70°C. The device is housed in a surface-mount PLCC-68 package.

Feature Summary

• Provides independent read/write ports for simultaneous data access
• Supports asynchronous parallel data transfer without clock synchronization
• Operates on standard 5V logic levels for broad compatibility

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in industrial control networks

Procurement Notes

Verify the specific suffix J8 to confirm the PLCC-68 surface mount package configuration. Confirm RoHS compliance status as documentation indicates non-compliance. Check for end-of-life notices or obsolescence warnings from Renesas before finalizing procurement plans due to potential supply constraints.

Selection Notes

Select this component when a fast 12 ns access time is required for dual-port memory operations. Ensure the design accommodates the PLCC-68 footprint and 5V logic requirements. Consider thermal management for the specified current draw in enclosed environments.

Part Context

This part belongs to the Renesas 7005S series of dual-port SRAMs. Variants in this series differ primarily by access speed and package type. The 7005S12J8 represents the faster 12 ns performance tier within the synchronous/asynchronous asynchronous family, designed for high-throughput applications requiring low latency.

Replacement Considerations

Cross-reference with IDT7005S12J8 for pin-compatible alternatives. Verify electrical specifications match exactly before substitution.
