7133LA35J

Overview

The Renesas Electronics Corporation 7133LA35J is a dual-port static random access memory integrated circuit. It provides a storage capacity of 32 kbit organized as 2K x 16 words. The device features an asynchronous parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in a 68-PLCC package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems.
• Asynchronous operation allowing flexible timing control without reliance on a global clock signal.
• CMOS technology implementation for efficient power consumption characteristics.

Applications

• High-speed data buffering between asynchronous system components
• Cache memory implementation in embedded processing architectures
• Data storage in telecommunications equipment requiring dual-access capabilities

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements against specific project regulations, as this variant may not meet current environmental standards. Validate package integrity upon receipt to ensure pin alignment matches the 68-PLCC specification before integration into assembly processes.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Ensure the design accommodates the 68-PLCC footprint and 35 ns access speed constraints. Verify that the operating temperature range aligns with the intended application environment and that the 5V logic levels match the system interface requirements.

Part Context

This part belongs to the IDT/Renesas 7133SA/LA series of dual-port SRAM devices. These components are designed for applications requiring high-speed data exchange between two independent masters. The LA suffix typically denotes commercial temperature range specifications compared to industrial variants.

Replacement Considerations

IDT7133LA35J serves as a direct equivalent designation. Verify pin compatibility and electrical parameters before substitution. Check manufacturer documentation for any functional differences between legacy IDT branding and current Renesas production runs.
