7133LA45J

Overview

The Renesas Electronics Corporation 7133LA45J is a dual-port, asynchronous 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 a parallel interface with a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-pin PLCC package measuring 24.21x24.21 mm. The component is designed for commercial temperature ranges.

Feature Summary

• Supports simultaneous independent read/write operations on two separate ports
• Utilizes CMOS technology for low power consumption
• Provides high-speed data transfer via parallel interface
• Compatible with standard TTL logic levels

Applications

• High-performance embedded systems requiring fast local memory
• Network equipment buffer memory applications
• Industrial control system data logging
• Telecommunications signal processing units

Procurement Notes

Verify the specific suffix J indicates the 68-PLCC package configuration. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check manufacturer lifecycle status for availability constraints. Ensure voltage requirements match system design specifications before integration.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Compare access times against system clock speeds to ensure timing compatibility. Evaluate package size constraints relative to PCB layout limitations. Consider thermal dissipation requirements for enclosed industrial environments.

Part Context

This part belongs to the 7133SA/LA series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 7133SA45J but differs in package type and operating temperature range. The LA series typically denotes extended or specific commercial grade variations compared to the SA series.

Replacement Considerations

Direct substitutes include the IDT7133SA45J for functional equivalence. Verify pinout compatibility before swapping. Alternative packages such as TQFP require level shifting or adapter solutions.
