7134LA20JI

Overview

The Renesas Electronics Corporation 7134LA20JI is a static random-access memory (SRAM) integrated circuit featuring dual-port asynchronous technology. It provides a storage capacity of 32 kbit, organized as 4k words by 8 bits. The device supports parallel interface operations with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and includes two independent circuits for simultaneous read/write access. The component is housed in a 52-PLCC package with J-leads, measuring 19.13x19.13 mm. It functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access
• Asynchronous parallel interface for flexible system integration
• CMOS technology ensuring low power consumption

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications requiring dual access ports

Procurement Notes

Verify the specific suffix 'JI' against official Renesas documentation to confirm the 52-PLCC package and commercial temperature grade. Confirm RoHS compliance status via current datasheets. Check for End-of-Life notices or Product Change Notifications prior to procurement. Ensure compatibility with existing PCB footprints for 52-PLCC packages.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave operations. Compare access times and power dissipation against alternative SRAM families. Verify that the 52-PLCC package fits the assembly constraints. Consider humidity sensitivity levels during storage and handling procedures.

Part Context

This part belongs to the 7134LA series of dual-port SRAMs from Renesas. It shares architectural similarities with other variants like the 7134LA20JG8 but differs in package type and manufacturer designation history. The series is designed for high-reliability applications requiring fast, independent memory access paths.

Replacement Considerations

Publicly confirmed substitutes include IDT7134LA20JI. Verify pinout compatibility and electrical specifications before substitution.
