7201LA12TP

Overview

The Renesas 7201LA12TP is an asynchronous FIFO memory device housed in a 28-PDIP package. It provides a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 50MHz and features a typical access time of 12ns. It operates on a single power supply ranging from 4.5V to 5.5V, with a maximum supply current of 80mA. The device is designed for surface-mount or through-hole applications within an operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains without requiring a common system clock.
• Unidirectional bus architecture simplifies interface design for specific data flow requirements.
• CMOS technology ensures low power consumption while maintaining high-speed performance capabilities.

Applications

• Buffering data streams between components operating at different clock speeds
• Interface bridging in parallel communication systems
• Data buffering in industrial control networks

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet to ensure compatibility with your specific voltage and packaging requirements. Confirm that the 28-PDIP form factor matches your PCB footprint constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the supplier provides traceability documentation consistent with automotive or industrial standards if required for your final assembly.

Selection Notes

Select this component when designing systems requiring simple, reliable asynchronous buffering between parallel interfaces. The 512x9 word depth offers sufficient buffer space for moderate throughput variations. Consider the 12ns access speed relative to your system's maximum clock frequency to prevent data loss. Evaluate the 28-pin DIP package suitability for prototyping or legacy board replacements compared to modern surface-mount alternatives.

Part Context

This part belongs to the IDT 7200 series of high-performance asynchronous FIFOs, now manufactured under the Renesas Electronics brand following industry acquisitions. The series is widely recognized for its robustness in digital signal processing and telecommunications applications. The 7201 variant specifically targets general-purpose parallel data buffering needs where timing flexibility is critical.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the same 7200 series family. Verify electrical parameter equivalence before replacing with other manufacturers' asynchronous FIFOs.
