7202LA20JI8

Overview

The Renesas 7202LA20JI8 is an asynchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 9K bits, organized as 1K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 33.3MHz and an access time of 20ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 80mA. The device is housed in a 32-PLCC package with J-leads and is designed for surface mount installation.

Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Unidirectional bus direction simplifies interface design
• Relay capability supports signal buffering and level shifting

Applications

• Data buffering between asynchronous logic blocks
• Interface bridging in high-speed digital systems
• Signal relay applications requiring isolation

Procurement Notes

Verify the exact suffix designation against official Renesas documentation, as variations such as J8 or JGI8 may indicate different packaging or temperature grades. Confirm RoHS compliance status, as older revisions may not meet current environmental standards. Check for obsolescence notices, as this part number may be discontinued or subject to last-time buy restrictions.

Selection Notes

Select this component when a 1Kx9 asynchronous FIFO with 20ns speed is required. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 32-PLCC package constraints for PCB layout. Verify that unidirectional flow meets the application's data path requirements without needing bidirectional control signals.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFOs, which are CMOS parallel devices. The series typically includes variants with different depths and speeds, such as the 7201LA20J8 (512x9) and 7202LA20J8 (1Kx9). These components are designed for general-purpose memory buffering in industrial and commercial electronics.

Replacement Considerations

Official substitutes include IDT7202LA20J8 or IDT7202LA20SO depending on package preference. Cross-reference with other 1Kx9 20ns asynchronous FIFOs from compatible manufacturers if pin compatibility is verified.
