7201LA15TP

Overview

The Renesas Electronics Corporation 7201LA15TP 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 40MHz and an access time of 15ns. 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 28-PDIP package with through-hole mounting capabilities.

Feature Summary

• Asynchronous FIFO architecture for independent read and write clock domains
• Unidirectional bus directionality for standard data flow applications
• CMOS parallel interface supporting high-speed data transfer

Applications

• Data buffering between asynchronous logic systems
• Interface bridging in telecommunications equipment
• High-speed data acquisition systems requiring temporary storage

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations such as JG or SOGI8 indicate different packages like PLCC or SOIC. Confirm RoHS compliance status and moisture sensitivity levels prior to ordering. Check for end-of-life notices or discontinuation 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 4.5V to 5.5V operating voltage range. Consider the 28-PDIP package constraints if PCB layout requires through-hole technology. Verify that the 15ns access time meets the timing requirements of the target application interface.

Part Context

This part belongs to the Renesas 7201L family of CMOS parallel FIFOs. The family includes variants with different access times and package options, such as the 7201LA15JGI8 in PLCC-32 and the 7201LA15SOGI8 in SOIC-28. These devices are designed for general-purpose memory buffering in digital systems.

Replacement Considerations

Direct substitutes include other parts within the 7201L series with compatible pinouts and electrical characteristics. Verify package compatibility, as the 7201LA15TP uses a 28-PDIP footprint which differs from surface-mount alternatives.
