7134SA35J8

Overview

The Renesas Electronics Corporation 7134SA35J8 is a dual-port static random-access memory (SRAM) device. It features a storage capacity of 32 kbit organized as 4K x 8 bits. The component supports parallel asynchronous interface with an access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 300 mA. The device is designed for through-hole installation in a CDIP-SB-48 package. It functions reliably across an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location by two separate ports.
• Asynchronous operation allowing flexible timing control for both read and write cycles from either port.
• Extended industrial temperature rating supporting reliable performance in harsh environmental conditions.

Applications

• High-speed data buffering in industrial automation systems
• Real-time signal processing applications requiring low latency
• Embedded control systems operating in extreme temperature environments

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements as original specifications may not meet current regulations. Check for authorized distributors offering last-time buy options. Validate package integrity upon receipt. Ensure design-in compatibility with existing system constraints before final procurement decisions.

Selection Notes

Evaluate thermal management capabilities given the high maximum operating temperature. Consider pin compatibility with existing PCB layouts using the CDIP-SB-48 package. Assess power consumption against available supply rails within the specified voltage range. Verify that the 35 ns access time meets system timing requirements. Review long-term availability risks associated with discontinued product lines.
