7134LA20JG8

Overview

The Renesas Electronics Corporation 7134LA20JG8 is a high-speed, asynchronous dual-port static random access memory (SRAM) IC. It features a storage capacity of 32 kbit organized as 4K x 8 bits. The device supports parallel interface operation with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 52-pin PLCC package with J-leads. The component is designed for surface mount installation and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent access from two separate ports without hardware arbitration
• Asynchronous operation allowing flexible timing control for systems tolerant of external contention or wait states
• Automatic power-down mode controlled by chip enable signals to minimize standby power consumption

Applications

• Systems requiring simultaneous data access from multiple processors or controllers
• Buffering applications where on-chip port arbitration is not implemented
• High-speed data logging and temporary storage in industrial control environments

Procurement Notes

Verify the current lifecycle status before procurement, as official documentation indicates this specific part number may be subject to discontinuation notices. Confirm that the 52-PLCC package form factor remains compatible with existing PCB footprints. Ensure that the 20 ns access speed meets the system timing requirements. Validate RoHS compliance specifications against current regulatory standards for the target market.

Selection Notes

Select this component when a 32 kbit dual-port SRAM solution is required for asynchronous parallel interfaces. The 20 ns speed grade suits applications needing fast data throughput without complex synchronization logic. Consider the 52-PLCC package constraints for board space and mounting style. Verify that the commercial temperature range aligns with the operational environment, noting that industrial variants exist for wider thermal ranges.

Part Context

This device belongs to the 7134LA series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family, such as different speed grades or package options. The LA suffix typically denotes standard commercial temperature range operation. This series is designed for applications where simple, high-speed shared memory is needed without internal arbitration hardware.
