7200L12J8

Overview

The Renesas Electronics Corporation 7200L12J8 is an asynchronous FIFO memory device with a 2K x 9 organization. It features a 12 ns access time and supports a maximum clock frequency of 50 MHz. The component operates on a single 5.0 V supply voltage within the 4.5 V to 5.5 V range, drawing a maximum supply current of 80 mA. It utilizes a unidirectional bus interface and is housed in a 32-pin PLCC package with dimensions of 13.97 mm x 11.43 mm x 2.79 mm. The device functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• CMOS parallel interface technology

Applications

• Data buffering between disparate system speeds
• Interface bridging in digital logic systems
• Temporary storage in high-speed data acquisition chains

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Review official discontinuation notices for final purchase timing constraints. Ensure compatibility with existing board layouts using the specified PLCC footprint.

Selection Notes

Evaluate the 2K x 9 depth against specific buffer requirements. Confirm that the 12 ns access speed meets system timing margins. Verify power supply stability within the 4.5 V to 5.5 V range. Assess thermal management needs for the 80 mA maximum current draw in the target environment.
