7142LA5J8

Overview

The Renesas Electronics Corporation 7142LA5J8 is a 16K-bit (2K x 8) dual-port static random-access memory (SRAM) IC. It features asynchronous parallel interface operation with a typical access time of 5 nanoseconds. The device operates within a supply voltage range of 4.5V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. It is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) surface-mount package, designed for high-speed data buffering and storage applications requiring independent port access.

Feature Summary

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

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control networks

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm moisture sensitivity level handling requirements prior to assembly. Ensure compatibility with existing PCB footprints and voltage levels. Review latest datasheet revisions for any pinout or electrical specification updates before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access. Compare access times against system timing constraints. Verify package compatibility with automated assembly processes. Consider thermal performance within the specified operating temperature range for reliable long-term operation in target environments.

Part Context

Part of the 7142LA series of dual-port SRAMs. Shares architectural similarities with other variants in the family while differing in access speed specifications. Designed for applications requiring non-blocking simultaneous read/write operations across two distinct ports.

Replacement Considerations

IDT7142LA5J8 serves as a direct functional equivalent under Intel/IDT branding. Verify pin compatibility and electrical parameters before substitution. Cross-reference with current Renesas portfolio for modern alternatives if availability is critical.
