7132LA55J

Overview

The Renesas Electronics Corporation 7132LA55J is a static random access memory (SRAM) device featuring a 16 kbit storage capacity organized as 2k x 8. It operates with an asynchronous parallel interface and provides a maximum access time of 55 ns. The component supports a supply voltage range from 4.5 V to 5.5 V, with a maximum power consumption of 140 mA. Designed for commercial applications, it functions within a temperature range of 0°C to +70°C. The integrated circuit utilizes a surface-mount PLCC-52 package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation without requiring a system clock signal
• CMOS technology ensuring low power consumption during active and standby modes

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in industrial control units

Procurement Notes

Verify the exact suffix designation against official documentation, as variations such as CB or J may indicate differences in package type or operating temperature range. Confirm RoHS compliance status prior to integration, as specific manufacturing batches may not meet current environmental directives. Ensure the selected variant matches the required thermal and physical constraints for the target design.

Selection Notes

Select this component when a dual-port SRAM with 16 kbit capacity and 55 ns speed is required. Compare against the 7132SA series for commercial temperature ranges if lower cost is prioritized over extended industrial specifications. Verify that the PLCC-52 package footprint aligns with the printed circuit board layout and assembly capabilities available for the production run.

Part Context

This device belongs to the Renesas 7132 family of CMOS dual-port RAMs. The family includes variants with different capacities and speeds, such as the 7132SA for commercial use and the 7132LA for extended industrial temperatures. These components are designed for high-performance applications requiring independent port access and fast data throughput.

Replacement Considerations
