7132SA25J

Overview

The Renesas Electronics Corporation 7132SA25J is a CMOS dual-port static random access memory (SRAM) device. It provides a storage capacity of 16 kilobits, organized as 2048 words by 8 bits. The component features an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems
• Asynchronous operation allowing flexible timing integration without external clock synchronization
• CMOS technology providing low power consumption relative to older bipolar implementations

Applications

• High-speed data buffering between disparate system components
• Cache memory implementation in embedded processing architectures
• FIFO buffer applications requiring concurrent read and write operations

Procurement Notes

This specific part number is officially discontinued and no longer manufactured by Renesas Electronics. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory channels. Designers must confirm end-of-life status before finalizing procurement plans to avoid supply chain disruptions.

Selection Notes

Engineers should evaluate the 7132SA25J primarily for legacy system maintenance or repair scenarios where original specifications are mandatory. New designs should consider modern equivalents that offer improved performance metrics, enhanced reliability standards, and active manufacturing support to ensure long-term project viability.

Part Context

The 7132SA25J belongs to the broader 7132 series of dual-port SRAMs produced by Renesas Electronics. This family is characterized by high-speed asynchronous access and independent port control. The device represents a standard solution for applications requiring non-blocking data exchange between multiple masters in complex electronic systems.

Replacement Considerations

Public confirmed substitute part numbers include IDT7132LA25JGB and 7132SA25J8/C. These alternatives share similar functional characteristics but may differ in packaging, pinout compatibility, or environmental ratings. Cross-referencing datasheets is essential to verify mechanical and electrical fit.
