7134SA45J8

Memory IC Overview

The Renesas Electronics Corporation 7134SA45J8 is a dual-port static random access memory (SRAM) device with a storage capacity of 32 kbit, organized as 4k x 8. It features an asynchronous parallel interface and a maximum access time of 45 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 240 mA. It supports surface mount installation in a 52-PLCC package and functions within a temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations at two separate ports
• Asynchronous parallel interface for flexible system integration without clock synchronization requirements
• CMOS technology providing high-speed data access capabilities

Memory IC Applications

• High-performance embedded systems requiring concurrent data handling
• Industrial equipment control units needing reliable volatile memory
• Telecommunications infrastructure supporting real-time signal processing

Memory IC Procurement Notes

Verify the obsolete status and discontinuance notifications from Renesas Electronics before procurement planning. Confirm that the 52-PLCC package dimensions match your PCB footprint requirements. Ensure compatibility with existing 4.5V to 5.5V power rails. Check for moisture sensitivity level constraints during storage and soldering processes. Validate that lead-free or specific RoHS compliance meets your regulatory standards.

Memory IC Selection Notes

Select this component when dual-port functionality is required for independent processor access to shared memory resources. Consider the 45 ns access speed for applications not demanding sub-nanosecond latency. Evaluate the 52-PLCC package suitability for your assembly line capabilities. Compare power consumption against other SRAM families if battery life is critical. Verify thermal performance within the specified operating temperature range.
