71342LA20JG

Memory IC Overview

The Renesas Electronics Corporation 71342LA20JG is a high-speed, dual-port static random-access memory (SRAM) device. It features a storage capacity of 32Kb organized as 4K words by 8 bits. The component operates with an asynchronous parallel interface and supports a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum access time of 20ns and a write cycle time of 20ns. The device is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount technology. It functions within a commercial operating temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two distinct ports.

Memory IC Applications

• High-speed data buffering in industrial control systems.

Memory IC Procurement Notes

Verify the specific suffix JG against official manufacturer documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check current product lifecycle status as this component may be obsolete or subject to change. Ensure the selected distributor provides valid traceability documents for quality assurance purposes.

Memory IC Selection Notes

Select this component when a dual-port SRAM with 32Kb capacity and 20ns speed is required. Compare against other variants in the 71342 series for different temperature ranges or package types. Verify that the 52-PLCC footprint matches the target PCB design constraints. Consider power consumption specifications relative to system thermal management capabilities.

Memory IC Part Context

This part belongs to the Renesas 71342LA series of dual-port SRAMs. These devices are designed for applications requiring concurrent access to shared memory resources. The LA suffix typically denotes commercial temperature range operation. The series offers hardware semaphore support for port arbitration.

Memory IC Replacement Considerations

Consult official datasheets for direct pin-to-pin replacements within the same family. Verify functional equivalence regarding access times and voltage levels before substitution.
