7201LA25TPI

Overview

The Renesas 7201LA25TPI is an asynchronous FIFO memory device with a capacity of 4.5K bits, organized as 512 words by 9 bits. It operates at a maximum data rate of 28.5 MHz with a 25 ns access time. The component supports unidirectional data transfer and functions within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 28-pin PDIP package and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Asynchronous first-in-first-out memory architecture
• Uni-directional data transfer capability
• Full and empty flag status indicators

Applications

• Data buffering in digital signal processing systems
• Interface bridging between disparate clock domains
• Temporary storage in high-speed data acquisition chains

Procurement Notes

This component is officially classified as obsolete or not recommended for new designs. Verify current availability through authorized distributors, noting that stock may be limited to surplus sources. Confirm RoHS compliance status and lead-free specifications prior to procurement, as legacy inventory may vary in environmental certification.

Selection Notes

Select this part for applications requiring simple, unidirectional asynchronous buffering with standard CMOS logic levels. Ensure the design accommodates the 28-pin DIP package constraints and verify that the 5V supply requirement aligns with the system power architecture. Consider pin compatibility if replacing older IDT variants.

Part Context

Part of the 7201L series of CMOS asynchronous FIFOs manufactured by Renesas Electronics. This series provides reliable data storage solutions for legacy and industrial systems requiring deterministic latency and straightforward interface protocols without complex configuration requirements.

Replacement Considerations

Verify pinout compatibility with IDT7201LA25TPI equivalents. Check functional equivalence regarding access times and voltage ranges before substitution.
