7133SA90JI8

Overview

The Renesas Electronics Corporation 7133SA90JI8 is a dual-port static random-access memory (SRAM) device with a storage capacity of 32 kilobits, organized as 2K words by 16 bits. It features asynchronous parallel interface operation with a maximum access time of 90 nanoseconds. The component operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. It is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Feature Summary

• Provides independent read/write access to memory locations via two separate ports without bus contention
• Supports asynchronous operation allowing flexible timing control for both port interfaces
• Integrates on-chip circuitry for low standby power consumption through chip enable control

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring simultaneous multi-port access

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status as legacy variants may differ. Check for active discontinuation notices or end-of-life notifications prior to finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when dual-port architecture is required for concurrent master-slave operations. Ensure the system design accommodates the 68-PLCC surface-mount footprint and 5V logic levels. Validate that the 90ns access speed meets the target application's throughput requirements compared to faster alternatives.

Part Context

This part belongs to the Renesas 7133SA series of high-speed dual-port SRAMs. These devices are engineered for applications demanding independent access to shared memory resources. The series typically offers various speed grades and packaging options to suit different industrial and commercial environments.

Replacement Considerations

Consult official substitution guides for compatible upgrades such as the 7133LA25JGI. Verify functional equivalence regarding pin configuration and voltage tolerances before implementing any cross-series replacements.
