7201LA12JI

Overview

The Renesas 7201LA12JI is an asynchronous FIFO memory IC with a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It supports unidirectional data transfer at a maximum clock frequency of 50MHz and features a 12ns access time. The device operates on a single 4.5V to 5.5V power supply with a maximum current consumption of 80mA. It is housed in a 32-PLCC package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface integration.
• Unidirectional bus architecture simplifies system design for specific data flow requirements.
• High-speed performance supports data buffering applications requiring 50MHz throughput.

Applications

• Data buffering between digital systems operating at different clock speeds
• Flow control in high-speed serial-to-parallel conversion circuits
• Interface bridging between microprocessors and peripheral devices

Procurement Notes

Verify the exact package type and pinout compatibility before procurement, as PLCC variants may differ from other packages in the series. Confirm RoHS compliance status for the specific manufacturing lot, as legacy stock may vary. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when unidirectional asynchronous buffering is required with 512x9 depth. Compare against bidirectional alternatives if two-way communication is needed. Verify that the 12ns access time meets the system timing constraints and that the PLCC package fits the available PCB footprint.

Part Context

This part belongs to the Renesas 7201L series of CMOS asynchronous FIFOs. The series offers various speed grades and package options to accommodate different system requirements. The 7201 variant specifically provides 512-word depth, distinguishing it from deeper or narrower configurations in the same family.

Replacement Considerations

The 7201LA12JG is listed as an upgrade alternative. Verify package differences, as JG denotes PLCC while other suffixes may indicate SOIC or DIP. Ensure functional equivalence regarding unidirectional operation and timing specifications before substitution.
