7132LA35L48B

Overview

The Renesas Electronics Corporation 7132LA35L48B is a high-speed dual-port static random-access memory (SRAM) device. It features a storage capacity of 16 kilobits, organized as 2K words by 8 bits per word. The component utilizes an asynchronous parallel interface with a maximum access time of 35 nanoseconds. It operates on a single 5V power supply, with voltage specifications ranging from 4.5V to 5.5V. The device is housed in a 48-pin Side Brazed package and supports surface mount installation. It is designed for industrial temperature ranges.

Feature Summary

• True dual-ported memory cells allow simultaneous independent access to the same memory location by two separate ports without conflict.
• Integrated on-chip port arbitration logic manages bus access automatically, eliminating the need for external discrete logic components.
• Supports battery backup operation with data retention capabilities down to 2V, ensuring data integrity during main power loss.
• Features automatic power-down functionality controlled by chip enable signals to minimize standby power consumption.

Applications

• High-speed data buffering in telecommunications equipment
• Real-time processing systems requiring low-latency memory access
• Industrial control systems operating in harsh environments
• Embedded applications needing reliable non-volatile-like behavior via battery backup

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as legacy variants may differ. Ensure proper handling procedures for the side-brazed ceramic package are followed during assembly to prevent mechanical stress or thermal damage. Validate that the 48-pin footprint matches the design layout precisely.

Selection Notes

Select this component when true dual-port capability is required for concurrent master-slave or peer-to-peer data exchange. Consider the 35ns access speed for synchronous-like performance without clock constraints. Evaluate the 48-pin side-brazed package suitability for high-reliability industrial or military applications. Compare against single-port alternatives if simultaneous access is not necessary to reduce cost and complexity.

Part Context

This part belongs to the 7132LA series of dual-port SRAMs manufactured by Renesas Electronics. It serves as a standalone 8-bit dual-port RAM or can function as a 'MASTER' unit paired with 'SLAVE' devices like the 7142 series for wider data buses. The LA suffix typically denotes industrial temperature range and specific packaging characteristics within the family.

Replacement Considerations

Public confirmed substitute part numbers: IDT7132LA35L48B. Verify pinout compatibility and electrical specifications before substitution. Note that the original manufacturer may have discontinued production; check current availability and lifecycle status of potential replacements.
