7007S35J

Memory IC Overview

The Renesas Electronics Corporation 7007S35J is a dual-port static random access memory (SRAM) device with a storage capacity of 256 kbit, organized as 32k x 8. It features an asynchronous parallel interface and a maximum access time of 35 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power consumption of 295 mA. It supports surface mount installation in a 68-PLCC package and functions within an operating temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two separate ports
• Asynchronous operation allowing flexible timing control for either port
• Single 5V power supply compatibility with TTL-compatible logic levels

Memory IC Applications

• High-speed data buffering between asynchronous system components
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring fast read/write cycles

Memory IC Procurement Notes

Verify the specific suffix designation carefully, as the 7007S35J may denote a distinct package or environmental variant compared to the 7007S35J8. Confirm RoHS compliance status, as documentation indicates potential non-compliance for certain variants. Check current lifecycle status, as this series is frequently subject to discontinuation notices. Ensure moisture sensitivity handling protocols are followed during assembly.

Memory IC Selection Notes

Select this component when a true dual-port SRAM is required for concurrent data access without external arbitration logic. Compare against single-port alternatives if only one active master exists. Evaluate the 68-PLCC package constraints against available board space. Consider the 35 ns access speed relative to the system clock requirements. Verify that the 0°C to +70°C commercial temperature range meets the operational environment specifications.

Memory IC Part Context

This part belongs to the Renesas 7007S35 family of high-speed dual-port SRAMs. These devices are designed to replace older discrete logic solutions by integrating port arbitration and semaphore signaling on-chip. The family typically offers various density options and access speeds to suit different memory subsystem architectures.
