7134LA25JGI8

Overview

The Renesas 7134LA25JGI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 4K words by 8 bits. The device features asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors or systems
• Asynchronous operation eliminating the need for external clock synchronization signals
• CMOS technology ensuring low power consumption during read and write cycles

Applications

• High-speed data buffering between microprocessors and peripheral devices
• Cache memory implementation in embedded control systems
• Data logging applications requiring rapid sequential write operations

Procurement Notes

Verify the specific suffix JGI8 against official Renesas documentation to confirm the exact package variant and moisture sensitivity level. Confirm RoHS compliance status through current datasheets, as manufacturing updates may alter environmental declarations. Ensure compatibility with existing PCB footprints for the 52-PLCC configuration before procurement.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access without arbitration logic. The 25 ns speed suits moderate-frequency asynchronous buses. Compare against single-port alternatives if only one master accesses the memory. Verify that the 52-PLCC package fits the assembly constraints compared to surface-mount options like TQFP.

Part Context

This part belongs to the 7134LA series of dual-port SRAMs from Renesas Electronics. It serves as a high-performance memory solution for applications needing independent port access. The series typically offers various speed grades and packaging options to accommodate different system timing and physical layout requirements.

Replacement Considerations

IDT7134LA25JGI is listed as an alias or direct substitute. Verify pinout and electrical specifications match exactly. Other family members like 7134LA35 offer slower speeds but similar interfaces.
