7130SA35CB

Memory IC Overview

The Renesas Electronics Corporation 7130SA35CB is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports a commercial operating temperature range of 0°C to 70°C. The component is housed in a 48-lead side brazed ceramic dual in-line package (CDIP-SB-48).

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two separate ports for high-throughput data handling.
• Utilizes CMOS technology to provide reliable volatile memory storage with standard parallel interface compatibility.
• Designed for robust performance in industrial environments through the use of hermetic ceramic packaging.

Memory IC Applications

• Real-time data buffering in telecommunications systems requiring low-latency access.
• High-speed cache memory implementation in embedded processing architectures.
• Data acquisition systems needing concurrent port access for signal processing tasks.

Memory IC Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity as ceramic packages are sensitive to mechanical stress. Check datasheet revisions for any pinout or electrical specification updates. Ensure environmental compliance requirements align with RoHS exemption status if applicable. Validate supplier authorization for legacy semiconductor components.

Memory IC Selection Notes

Select this part when dual-port functionality is required for concurrent master-slave memory access. Consider the 35ns speed grade for applications demanding moderate latency. Evaluate the CDIP-SB-48 package against available board space and mounting constraints. Compare power consumption specifications against system thermal limits during continuous operation.
