7142LA25JGI

Overview

The 7142LA25JGI is an asynchronous dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a storage capacity of 16 kbit, organized as 2K x 8 bits. The device features parallel interface access 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 surface-mount installation in a 52-PLCC package. The component is rated for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation without clock synchronization requirements
• Parallel data bus interface for direct system connectivity

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Real-time data logging in industrial control equipment

Procurement Notes

Verify the specific suffix JGI against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status through current datasheets, as legacy variants may differ. Check for obsolescence notices or product discontinuance announcements prior to procurement planning.

Selection Notes

Select this component when independent read/write access from two separate buses is required. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Verify that the 52-pin PLCC footprint matches the PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the 7142LA series of dual-port SRAMs designed for applications requiring high-speed data exchange between different processing domains. It serves as a bridge for data transfer in complex digital systems where latency must be minimized.
