7202LA12SOG8

Overview

The Renesas Electronics Corporation 7202LA12SOG8 is an asynchronous FIFO memory device housed in a 28-SOIC surface-mount package. It provides a storage capacity of 9K bits, organized as 1K words by 9 bits. The component supports a maximum data rate of 50MHz with a typical access time of 12ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 80mA. Designed for industrial reliability, it functions within a temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Supports retransmit capability to ensure data integrity during bus contention or error conditions.
• Configurable depth and width expansion options facilitate scalable system architecture design.

Applications

• Data buffering between high-speed processors and slower peripheral devices
• Interface bridging between different clock domains in communication systems
• Temporary storage in digital signal processing pipelines

Procurement Notes

Verify the specific suffix 'SOG8' against official Renesas documentation to confirm the 28-SOIC package variant and tape-and-reel packaging configuration. Ensure compatibility with RoHS3 standards and check for any recent PCN updates regarding assembly site changes or labeling modifications before finalizing procurement orders.

Selection Notes

Select this component when a 1Kx9 asynchronous FIFO is required in a compact 28-pin SOIC footprint. It is suitable for applications needing 50MHz throughput with 12ns latency. Consider alternative packages like PLCC if higher pin counts are needed, or verify if the 7201 series suffices for smaller 512x9 requirements.

Part Context

This part belongs to the IDT 7200L series of asynchronous FIFOs, originally developed by Integrated Device Technology (IDT) and now manufactured by Renesas Electronics. The series is widely used in legacy and modern embedded systems requiring reliable data buffering. The 7202 variant specifically offers double the depth of the 7201 model.

Replacement Considerations

Direct substitutes include the IDT7202LA12SOG8 alias. Verify pinout compatibility with other 7202-series variants such as 7202LA12JG8 if package changes are acceptable.
