7204L15JI

Overview

The Renesas Electronics Corporation 7204L15JI is an asynchronous FIFO memory device with a storage capacity of 36K bits, organized as 4K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum data rate of 40 MHz with a 15 ns access time. The component is housed in a 32-PLCC package and supports unidirectional bus directionality. It functions across a temperature range of -40°C to +85°C and has a maximum supply current of 120 mA.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• Surface-mount PLCC packaging for board integration

Applications

• Data buffering between disparate system speeds
• Protocol conversion interfaces
• Digital signal processing pipelines

Procurement Notes

Verify the specific suffix 'J' against official documentation to confirm package type and compliance status. Confirm RoHS compliance requirements as historical records may vary. Check for moisture sensitivity levels if reflow soldering is planned. Validate that the discontinued status does not impact long-term project viability or availability through authorized channels.

Selection Notes

Select this component when a 4K x 9 asynchronous FIFO is required with 15 ns performance. Ensure the design accommodates the 32-pin PLCC footprint and 4.5 V to 5.5 V power rails. Consider the 120 mA current draw for thermal management. Verify compatibility with existing logic families operating at 40 MHz data rates.

Part Context

This part belongs to the 7200 series of high-speed FIFOs from Renesas. It provides non-volatile-like data retention during power cycles via its static CMOS structure. The series is designed for applications requiring reliable data transfer between asynchronous clock domains without complex handshaking protocols.

Replacement Considerations

The 7204L12JG is listed as a similar replacement option.
