7133SA35J

Overview

The Renesas Electronics Corporation 7133SA35J is a static random access memory (SRAM) device featuring dual-port asynchronous technology. It provides a storage capacity of 32 kbit, organized as 2K x 16 bits. The component supports parallel interface operations with an access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and functions at temperatures between 0°C and +70°C. The device is housed in a 68-PLCC surface-mount package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation for flexible system integration
• CMOS technology ensuring low power consumption

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded controllers
• Real-time processing applications requiring concurrent read/write access

Procurement Notes

This component has reached end-of-life status and is no longer manufactured by Renesas Electronics. Availability is restricted to existing stock or surplus channels. Verify RoHS compliance carefully, as this specific variant is non-compliant. Confirm package integrity and moisture sensitivity handling prior to installation due to age.

Selection Notes

Designers should evaluate the 7133SA series for legacy compatibility requirements. Consider the 35 ns access speed and 5V logic levels when interfacing with other components. Ensure the PCB layout accommodates the 68-PLCC footprint. Review datasheet specifications for electrical characteristics to validate system timing constraints.

Part Context

The 7133SA35J belongs to the Renesas 7133SA family of dual-port SRAMs. This series is designed for applications requiring high-performance memory with independent port access. The part is historically significant in industrial and telecommunications equipment where reliable, fast memory was critical.

Replacement Considerations

Verify pin-to-pin compatibility with alternative dual-port SRAMs from Renesas or IDT. Check if newer variants offer RoHS compliance and extended temperature ranges. Ensure substitute parts match the 35 ns access time and 5V operating voltage requirements.
