7133SA35JI8

Overview

The Renesas Electronics Corporation 7133SA35JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits organized as 2K by 16 bits. The device utilizes a parallel interface with an access time and write cycle time of 35 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, measuring 24.21mm by 24.21mm. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent asynchronous access to the same memory location from two separate ports.

Applications

• High-performance processor secondary cache systems
• Real-time data buffering in industrial equipment
• Network communication buffer applications

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as this specific variant may not meet current environmental standards. Validate package integrity upon receipt. Ensure handling procedures account for moisture sensitivity level 3 specifications during assembly processes.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations without external arbitration logic. Consider the 68-PLCC package constraints for board layout. Verify that the 4.5V to 5.5V supply voltage aligns with system power rails. Assess thermal management needs for the specified industrial temperature range.
