7132LA35JI8

Overview

The Renesas Electronics Corporation 7132LA35JI8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 16 kbit, organized as 2K words by 8 bits. The device features a parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 52-PLCC package. The component is designed for commercial temperature ranges from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation without requiring a system clock signal
• CMOS technology providing low power consumption characteristics

Applications

• Buffering data between high-speed processors and slower peripherals
• Cache memory implementation in embedded systems
• Data storage in telecommunications equipment

Procurement Notes

Verify the exact suffix JI8 against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status as historical data indicates non-compliance for similar variants. Check current obsolescence status and lead times with authorized distributors. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when independent dual-port access is required for concurrent data handling. Compare against single-port SRAMs if only one processor needs access. Verify that the 35 ns speed meets system timing requirements. Ensure the 52-PLCC footprint fits the PCB layout constraints. Consider power dissipation limits at maximum operating temperatures.

Part Context

This part belongs to the Renesas 7132 series of dual-port SRAMs. It shares architectural similarities with other members like the 7132SA35J8 but differs in package configuration. The series is designed for applications requiring high-speed data buffering and protocol conversion between different bus speeds.

Replacement Considerations

Official substitutes include IDT7132LA35J8. Verify pin compatibility and electrical parameters before substitution. Check for updated packaging options such as tube or reel variations.
