7133SA70J8

Overview

The Renesas Electronics Corporation 7133SA70J8 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 features asynchronous parallel interface operation with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package measuring 24.21mm by 24.21mm. The component is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications in communication interfaces

Procurement Notes

Verify the specific suffix J8 against official datasheets to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status, as this part may not meet current environmental directives. Check manufacturer discontinuation notices for availability constraints and last-time-buy dates before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations between two masters. Ensure the system design accommodates the 68-PLCC surface-mount footprint and 70ns timing requirements. Verify that the 4.5V to 5.5V supply voltage aligns with the target application's power rails.

Part Context

This part belongs to the IDT/Renesas 7133 series of dual-port SRAMs. Variants in this family differ primarily in access speed and package type. The 7133SA70J8 specifically denotes the 70ns speed grade and PLCC packaging configuration within the broader 32Kb dual-port memory portfolio.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Potential alternatives include other 32Kb dual-port SRAMs with compatible pinouts and electrical specifications from the same manufacturer or qualified competitors.
