7201LA15JI

Overview

The Renesas 7201LA15JI is an asynchronous FIFO memory device with a capacity of 512 x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The component supports a data rate of 40 MHz and draws a maximum supply current of 80 mA. It utilizes a unidirectional bus architecture and is housed in a 32-PLCC package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data bus architecture
• CMOS technology implementation

Applications

• Data buffering between different clock domains
• Interface bridging in high-speed digital systems
• Temporary storage in communication protocols

Procurement Notes

This part number is obsolete and no longer manufactured. Verification of availability is restricted to direct replacement components or alternative packaging types offered by the manufacturer. Procurement must focus on confirmed substitute part numbers rather than original stock, as the primary item is discontinued.

Selection Notes

Selection requires identifying a direct replacement due to obsolescence. The 7201LA15JGI8 is listed as a direct substitute. Ensure the replacement maintains compatibility with the required 512 x 9 bit depth, 15 ns access time, and PLCC-32 package form factor for existing board designs.

Part Context

The 7201L series represents a family of asynchronous FIFOs from Renesas Electronics. This specific model belongs to the 7201 subset, characterized by its 512-word depth and 9-bit width configuration. It is designed for applications requiring reliable data buffering without complex control logic.

Replacement Considerations

The 7201LA15JGI8 is a confirmed direct replacement. Verify pinout and electrical specifications match the original design requirements before integration.
