7133SA70GM

Overview

The 7133SA70GM is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. 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 100-pin TQFP package. The component is designed for commercial temperature ranges from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface supporting standard logic levels
• CMOS technology ensuring low power consumption during standby and active modes

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring fast access

Procurement Notes

Verify the specific suffix GM against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for end-of-life notices or obsolescence announcements prior to procurement planning.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. Ensure the system design accommodates the 100-pin TQFP footprint and thermal requirements. Verify that the 70ns access speed meets the timing constraints of the target application bus.

Part Context

This part belongs to the 7133SA family of dual-port SRAMs. Variants differ primarily in access speed, package type, and operating temperature range. The SA designation typically indicates commercial temperature grades, while LA variants often cover extended industrial ranges.
