7133LA25J

Overview

The Renesas Electronics Corporation 7133LA25J is a static random-access memory (SRAM) integrated circuit featuring dual-port asynchronous architecture. It provides a storage capacity of 32 kilobits organized as 2K words by 16 bits. The device supports parallel interface communication with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) surface-mount package.

Feature Summary

• Dual-port asynchronous SRAM architecture enabling independent simultaneous access
• CMOS technology for high-speed data processing capabilities
• Parallel interface supporting standard digital logic connections

Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded computing devices
• Data storage in industrial control applications

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the original specification indicates non-compliance. Validate package integrity and pin configuration against design specifications before integration into final assemblies.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the 68-PLCC package dimensions for PCB layout constraints and thermal management requirements during the design phase.

Part Context

This part belongs to the Renesas 7133 series of dual-port SRAMs, designed for applications requiring fast, independent access from two different masters. The 'LA' suffix typically denotes an extended temperature range compared to commercial variants, suitable for broader environmental conditions.

Replacement Considerations

The 7133SA70JI is listed as an upgrade alternative. Verify electrical compatibility and pin alignment before substitution.
