7132SA35J8

Memory IC Overview

The Renesas Electronics Corporation 7132SA35J8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device features parallel interface access with a maximum access time and write cycle time of 35 nanoseconds. It operates on a single 4.5V to 5.5V power supply and is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package measuring 19.13x19.13 mm. The component supports surface mount installation and functions within an ambient temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports without external arbitration logic.
• Includes on-chip port arbitration logic that manages bus conflicts automatically.
• Features an automatic power-down mode controlled by chip enable signals for low standby power consumption.

Memory IC Applications

• Stand-alone 8-bit dual-port memory systems
• Master dual-port RAM modules in 16-bit or wider word width configurations
• Real-time data buffering applications requiring error-free operation

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as this specific variant may not meet current environmental standards. Validate package integrity upon receipt to ensure pin alignment matches the 52-PLCC specification. Review datasheet revisions for any recent manufacturing site changes or labeling updates before final integration.

Memory IC Selection Notes

Select this component when true dual-port functionality is required for concurrent read/write operations. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the 35 ns speed limit for timing constraints. Verify thermal management capabilities for the commercial temperature range. Evaluate footprint compatibility with the 52-PLCC soldering process.

Memory IC Part Context

This part belongs to the 7132SA series of high-performance CMOS dual-port SRAMs manufactured by Renesas Electronics. It serves as a core memory solution for embedded systems needing fast, conflict-free data sharing between two processors or controllers. The series is designed to eliminate the need for discrete logic gates typically required for port arbitration in multi-port memory designs.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative sourcing requires careful evaluation of electrical compatibility and physical footprint matching.
