7143LA90J8/S2418

Overview

The Renesas 7143LA90J8/S2418 is a dual-port static random-access memory (SRAM) integrated circuit with an asynchronous interface. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features a parallel interface and supports a supply voltage range of 4.5V to 5.5V. It operates within a temperature range of 0°C to 70°C. The component utilizes a 68-pin PLCC package for surface-mount installation.

Feature Summary

• Dual-port architecture enabling independent access from two separate systems
• Asynchronous operation without requiring a system clock signal
• Parallel data interface for direct connection to microprocessors

Applications

• Real-time data buffering in industrial control systems
• High-speed cache memory for embedded processors
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm pinout compatibility and moisture sensitivity level requirements. Ensure the operating environment remains within the specified commercial temperature limits. Confirm that the power supply voltage does not exceed the maximum rating during transient conditions. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when independent simultaneous read/write access is necessary for two distinct masters. The 32Kb capacity suits moderate-sized buffer requirements. The PLCC-68 package requires appropriate PCB footprint design. Consider thermal management if the device operates near the upper temperature limit under continuous load.

Part Context

This part belongs to the Renesas 7143SA/LA series of high-performance dual-port SRAMs. These devices are designed for applications demanding fast data transfer between different processing units. The series offers various speed grades to match specific timing constraints in complex digital systems.

Replacement Considerations
