7133LA25JI8

Overview

The Renesas Electronics Corporation 7133LA25JI8 is a dual-port static random access memory (SRAM) device with a storage capacity of 32 kbit, organized as 2K x 16. It features an asynchronous parallel interface with a maximum access time of 25 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 300 mA. It is housed in a 68-pin PLCC package and supports surface mount installation. The device functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data acquisition systems requiring rapid parallel access

Procurement Notes

Verify the specific suffix JI8 against official Renesas documentation to confirm the exact package type and temperature grade. Ensure compatibility with existing board layouts for the 68-PLCC footprint. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference part aliases such as IDT7133LA25JI8 for sourcing accuracy.

Selection Notes

Select this component when a 25 ns access speed and dual-port capability are required for 32 kbit memory applications. The industrial temperature range (-40°C to +85°C) makes it suitable for harsh environments compared to commercial variants. Consider the 68-PLCC package constraints for PCB space and routing density.

Part Context

This part belongs to the Renesas 7133LA series of CMOS dual-port SRAMs. It shares architectural similarities with other members like the 7133SA25J but differs in package and temperature specifications. The LA series typically denotes extended industrial temperature ranges and specific packaging options distinct from the SA series.

Replacement Considerations

IDT7133LA25JI8 is a confirmed equivalent part number alias for this component.
