7201LA25JI

Overview

The Renesas 7201LA25JI is a CMOS asynchronous first-in, first-out (FIFO) memory device featuring a storage capacity of 512 words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 28.5 MHz with a typical access time of 25 ns. The component utilizes a unidirectional bus architecture and is housed in a 32-PLCC surface-mount package. Designed for industrial temperature ranges, it provides reliable data buffering for parallel digital systems.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible system integration
• CMOS technology ensures low power consumption and high-speed data transfer capabilities
• Unidirectional data flow simplifies interface design for specific buffer applications

Applications

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

Procurement Notes

Verify RoHS compliance status as the source indicates non-compliance. Confirm availability through authorized distributors, noting potential discontinuation or limited stock. Ensure the PLCC-32 package matches your PCB footprint requirements. Validate that the 4.5V to 5.5V supply range aligns with your system's power rails before finalizing procurement.

Selection Notes

Select this component when a unidirectional FIFO is required for 9-bit wide data paths. The 25 ns access time suits moderate-speed applications compared to faster alternatives. Consider the PLCC-32 package constraints if space is limited. Verify that the asynchronous nature fits your timing requirements rather than synchronous designs.

Part Context

Part of the 7201L series, this device belongs to Renesas' legacy CMOS FIFO portfolio. It shares architectural similarities with other members like the 7201LA25J8 but differs in packaging and specific revision details. The series targets general-purpose memory buffering needs in industrial and commercial electronics.

Replacement Considerations

IDT7201LA25JI is a documented alias for this part number. Cross-reference pinouts and electrical specifications carefully when substituting with equivalent parts from other manufacturers to ensure compatibility.
