7133SA90J

Overview

The Renesas Electronics Corporation 7133SA90J is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time and write cycle time of 90 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts. The component is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package with J-leads, measuring 24.21mm by 24.21mm. It supports surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for straightforward integration into standard digital systems
• CMOS technology ensuring low power consumption relative to older bipolar SRAM alternatives

Applications

• Data buffering in high-speed communication equipment
• Cache memory implementation in industrial control systems
• Temporary data storage in embedded processing applications

Procurement Notes

Verify the specific suffix designation carefully, as the 'J' indicates a PLCC package which differs from PGA or TQFP variants in the same series. Confirm RoHS compliance status, as older manufacturing lots may not meet current environmental directives. Check for end-of-life notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a dual-port memory solution with a 90ns speed grade is required in a PLCC form factor. Ensure the system design accommodates the 4.5V to 5.5V supply requirement. Compare against other suffixes if different package types like PGA or lower latency speeds are needed for the specific application constraints.

Part Context

This part belongs to the 7133SA family of dual-port SRAMs manufactured by Renesas Electronics. The family offers various speed grades and package options to suit different performance and physical layout requirements. The 7133SA90J specifically targets applications needing moderate speed in a compact leadless chip carrier format.

Replacement Considerations

The 7133LA25JGI is listed as an upgrade alternative. Verify pin compatibility and electrical specifications before substitution.
