7132LA25J

Memory IC Overview

The 7132LA25J is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-lead Plastic Leadless Chip Carrier (PLCC) package. The component is designed for commercial temperature ranges from 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors

Memory IC Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved replacement alternatives. Compliance with RoHS directives should be confirmed via specific datasheet documentation, as legacy parts may not meet current environmental standards. Engineering samples are unlikely to be available.

Memory IC Selection Notes

Designers requiring this specific memory configuration must evaluate alternative components due to the discontinuation status. Selection criteria should focus on matching the 16Kb capacity, 25ns speed, and 52-pin PLCC footprint. Compatibility with existing board layouts and software drivers must be verified when transitioning to successor devices or pin-compatible upgrades offered by the manufacturer.

Memory IC Part Context

The 7132LA25J belongs to the Renesas 7132 series of dual-port SRAMs. This family is characterized by high-speed CMOS technology and independent port operations. The 'LA' suffix typically denotes extended temperature or specific packaging variations compared to the standard 'SA' series. These devices were widely used in applications requiring concurrent read/write access without bus contention.

Memory IC Replacement Considerations

The IDT7132LA25JG is listed as an upgrade alternative. Engineers should verify electrical compatibility and pin assignments before substitution.
