7142LA25JI8

Overview

The Renesas Electronics Corporation 7142LA25JI8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits organized as 2K by 8 bits. The device features a parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent read and write operations on separate ports
• Asynchronous operation for flexible system timing integration
• CMOS technology ensuring low power consumption during standby and active states

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring wide temperature tolerance

Procurement Notes

Verify RoHS compliance status, as the source indicates non-compliance. Confirm end-of-life or discontinuation notices prior to procurement. Ensure the PLCC-52 package footprint matches the target design. Validate that the 4.5V to 5.5V supply requirement aligns with the system power rails. Check for moisture sensitivity level constraints during assembly.

Selection Notes

Select this component when a dual-port SRAM with 16Kb capacity and 25ns speed is required. The PLCC-52 package suits surface-mount designs compatible with J-leaded footprints. Verify compatibility with 5V logic levels. Consider the industrial temperature range if operating in harsh environments. Ensure the asynchronous interface meets the system bus timing requirements.

Part Context

This part belongs to the Renesas 7142 series of dual-port SRAMs. It shares architectural similarities with other members like the 7132SA/LA variants but differs in organization and pin count. The 'LA' suffix typically denotes specific package or temperature characteristics within the family. It serves as a high-speed memory solution for legacy and specialized industrial applications.
