7132LA25L48B

Overview

The Renesas Electronics Corporation 7132LA25L48B is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The device supports asynchronous parallel interface with an access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is designed for surface mount installation in a 48-LCC package measuring 14.22x14.22 mm. The component supports an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations by two masters
• Asynchronous operation without requiring a system clock signal
• CMOS technology providing low power consumption characteristics

Applications

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

Procurement Notes

Verify the specific suffix L48B to confirm the 48-lead LCC package configuration and pinout compatibility. Confirm RoHS compliance status, as older variants may not meet current environmental directives. Check moisture sensitivity level requirements for surface mount assembly processes. Ensure the 25 ns speed grade matches the system timing constraints. Validate that the extended temperature range meets the operational environment specifications.

Selection Notes

Select this component when dual-master access is required for shared memory resources. The 25 ns speed provides a balance between performance and power efficiency. The wide temperature range suits harsh industrial environments. Compare against single-port alternatives if only one master is active. Consider the 48-LCC footprint constraints during PCB layout design.

Part Context

This part belongs to the Renesas 7132 series of dual-port SRAMs. It shares architectural similarities with other members like the 7132LA20J but differs in speed grade and package type. The series is characterized by CMOS technology and asynchronous parallel interfaces. It serves as a legacy component in high-reliability memory applications.
