7132SA55J

Overview

The Renesas Electronics Corporation 7132SA55J is a static random access memory (SRAM) device with a storage capacity of 16 kbit, organized as 2k x 8. It features an asynchronous parallel interface and a maximum access time of 55 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 155 mA. Designed for surface mount installation, it is housed in a 52-PLCC package. The device supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations by two processors
• Asynchronous operation allowing flexible timing integration without clock synchronization requirements
• CMOS technology providing low power consumption characteristics relative to older SRAM generations

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded control systems
• Data storage in industrial automation controllers

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm RoHS compliance requirements against project specifications, as this part may not meet current environmental directives. Check for valid replacement options such as the 7132LA20JG if availability is critical. Ensure that the 52-PLCC package footprint matches existing PCB designs. Validate lead times for remaining stock through authorized distributors.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access to shared memory resources. The 55 ns access speed suits applications needing moderate performance without complex synchronous interfaces. Consider the 52-PLCC package constraints for board space and thermal management. Evaluate the commercial end-of-life status against long-term production requirements. Compare power consumption metrics with newer alternatives if efficiency is a primary design driver.

Part Context

This device belongs to the Renesas 7132SA series of CMOS dual-port RAMs. It shares architectural similarities with other parts in the family but differs in specific speed grades and packaging options. The series was designed to provide high-reliability memory solutions for demanding electronic applications. Manufacturing transitions between IDT and Renesas have affected part numbering conventions across the product line.

Replacement Considerations

The 7132LA20JG is listed as an upgrade alternative by the manufacturer.
