7133SA55G

Overview

The Renesas Electronics Corporation 7133SA55G 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 of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports through-hole installation in a 68-pin ball grid array package measuring 29.46mm by 29.46mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations from two separate ports.

Applications

• High-speed data buffering in telecommunications equipment.

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status, as this variant may not meet current environmental directives. Check for end-of-life notifications or product discontinuance notices prior to procurement planning. Ensure the selected package type matches the intended PCB footprint requirements.

Selection Notes

Select this component when a non-volatile dual-port memory solution with parallel interface is required for systems operating at standard 5V logic levels. Consider the 68-PGA package constraints for mechanical integration. Evaluate thermal performance within the specified commercial temperature range. Verify that the 55ns access speed meets the system timing requirements for the target application environment.

Part Context

This part belongs to the 7133SA series of CMOS dual-port SRAMs manufactured by Renesas Electronics. The series offers various access speeds and packaging options to suit different embedded memory needs. The 7133SA55G specifically targets applications requiring moderate speed and reliable data retention in a through-hole format.

Replacement Considerations

Consult official datasheets for cross-reference information. Verify functional equivalence regarding pin configuration and voltage levels before substitution.
