7201LA50J

Overview

The Renesas Electronics Corporation 7201LA50J is an asynchronous FIFO memory device belonging to the 7201L series. It features a storage capacity of 4.5K organized as 512 words by 9 bits. The component supports unidirectional bus operation with a maximum data rate of 28.5MHz and an access time of 35ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. The device is housed in a 32-PLCC package and functions reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous dual-clock architecture for independent read and write operations
• Unidirectional data flow capability for specific interface requirements
• CMOS technology ensuring low power consumption during operation

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary data storage in high-speed digital signal processing chains

Procurement Notes

Verify the exact suffix designation, as official documentation lists variants such as 7201LA50JG8 or 7201LA50JI8. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check for end-of-life notices or discontinuance announcements from Renesas Electronics to ensure long-term availability for production cycles.

Selection Notes

Select this component when a 512x9 word depth is required for asynchronous buffering. Ensure the system design accommodates the 32-pin PLCC footprint and the 4.5V to 5.5V power supply constraints. Verify that the 35ns access time meets the timing requirements of the connected logic interfaces.

Part Context

This part belongs to the Renesas 7201L family of asynchronous FIFOs, which provides flexible memory solutions for parallel data transfer applications. The family includes various speed grades and organization options, allowing designers to choose components based on specific throughput and latency requirements for embedded systems.

Replacement Considerations

Cross-reference with IDT7201LA50JG8 or IDT7201LA50JI8 for potential pin-compatible alternatives. Verify electrical specifications and package dimensions match before substitution.
