7204L12PI

Overview

The Renesas Electronics Corporation 7204L12PI is an asynchronous FIFO memory device with a capacity of 4K x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 50 MHz. The component features a 12 ns access time and is housed in a 28-PDIP package. It functions as a unidirectional buffer suitable for digital signal processing applications.

Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Unidirectional data flow simplifies interface design
• CMOS technology ensures low power consumption

Applications

• Digital signal processing systems
• Data buffering between different clock domains
• Interface bridging in embedded systems

Procurement Notes

Verify the specific suffix 'PI' corresponds to the 28-pin DIP package and the required operating temperature range. Confirm RoHS compliance status as historical documentation may vary. Check for obsolescence notices or lifecycle status updates from Renesas before finalizing procurement plans.

Selection Notes

Select this part when a unidirectional asynchronous FIFO with 36 Kbit capacity is required. Ensure the system timing accommodates the 12 ns access speed. Compare against bidirectional alternatives if dual-clock domain flexibility is needed. Verify package compatibility with existing PCB footprints.

Part Context

This component belongs to the 7204 series of high-speed asynchronous FIFOs manufactured by Renesas Electronics. The series offers various access times and package options to support diverse memory buffering requirements in industrial and consumer electronics applications.

Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as variants with different access times or packages. Verify functional equivalence regarding bus width and depth before substitution.
