7202LA20J

Overview

The Renesas 7202LA20J is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates at a maximum data rate of 33.3MHz with a 20ns access time. The component supports unidirectional bus direction and includes relay capability. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 80mA. The device is designed for surface mount installation in a 32-PLCC package (14x11.46mm) and operates across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains without synchronization requirements.
• Relay capability enables the preservation of stored data during power-down or reset events.
• Supports depth and width expansion for flexible system integration.

Applications

• Data buffering between components operating at different clock speeds
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix J indicates the 32-PLCC package configuration. Confirm RoHS compliance status as older variants may differ. Check for obsolescence notices from Renesas, as this series has undergone lifecycle changes. Ensure the required 4.5V to 5.5V supply voltage aligns with your system design constraints before procurement.

Selection Notes

Select this model when a 9K bit asynchronous FIFO with 20ns speed is required. The 32-PLCC package suits board space constraints compatible with this footprint. Consider the 80mA max current draw for power budgeting. Verify that unidirectional data flow meets the application's interface needs, as bidirectional options exist in other series members.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFO memories. It shares core architecture with variants like the 7202LA12JG and 7202LA30LB, differing primarily in access speed and package type. The 7202LA20J specifically targets applications requiring moderate speed performance in a standard PLCC form factor.

Replacement Considerations

Direct substitutes include IDT7202LA20SO for SOIC-28 packaging or 7202LA12JG for faster 12ns performance in PLCC. Verify pin compatibility and electrical specifications before substitution. Consult Renesas PCN documents for official replacement recommendations.
