7200L25JI

Overview

The Renesas Electronics Corporation 7200L25JI is an asynchronous FIFO memory integrated circuit designed for high-speed data buffering applications. It features a storage capacity of 2.25K bits, organized as 256 words by 9 bits. The device supports unidirectional data flow with a maximum clock frequency of 28.5MHz and a typical access time of 25ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. The component is housed in a 32-PLCC package with J-leads, measuring 14mm by 11.46mm, and is rated for commercial temperature operation from 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Unidirectional data path simplifies system design for point-to-point buffering scenarios.
• CMOS technology ensures low power consumption while maintaining high-speed performance capabilities.

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary storage in digital signal processing chains

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's latest documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status as older revisions may differ. Check for End-of-Life notices or obsolescence warnings before finalizing procurement plans. Ensure the 32-PLCC package footprint matches the target PCB layout requirements.

Selection Notes

Select this component when a small, fast, unidirectional buffer is required for 9-bit wide data paths. Compare against bidirectional alternatives if two-way communication is needed. Verify that the 4.5V to 5.5V supply voltage aligns with the system's power rails. Consider the 256-word depth sufficiency for the intended application latency requirements.

Part Context

This part belongs to the Renesas 7200L series of asynchronous FIFO memories. The series offers various depths and speeds to suit different buffering needs. The 7200L25 variant specifically targets applications requiring 25ns access times. It is distinct from the 72V series which typically operates at lower voltages.

Replacement Considerations

Publicly confirmed substitute: 7200L12JG. This alternative is listed as an upgrade option by the manufacturer. Verify functional equivalence regarding speed and voltage requirements before substitution.
