7142LA100CB

Memory IC Overview

The Renesas Electronics Corporation 7142LA100CB is a static random-access memory (SRAM) integrated circuit belonging to the 7142LA series. It features a storage capacity of 16 kilobits organized as 2K by 8 bits. The device utilizes CMOS dual-port asynchronous technology with parallel interface capabilities. It operates within a supply voltage range of 4.5V to 5.5V and supports an access time of 100 nanoseconds. The component is housed in a 48-pin ceramic dual in-line package with sidebend leads (CDIP-SB-48).

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.
• CMOS technology providing low power consumption characteristics relative to older bipolar implementations.
• Asynchronous operation allowing flexible timing control without external clock synchronization.

Memory IC Applications

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

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental directives. Validate pin compatibility and thermal specifications for existing PCB footprints before integration into new designs.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent host and peripheral access. Ensure system voltage levels align with the specified 4.5V to 5.5V operating range. Consider the 100ns access speed against application latency requirements. Evaluate the CDIP-SB-48 package constraints for mechanical fit and mounting orientation in the target assembly.
