7201LA20J

Overview

The Renesas 7201LA20J is an asynchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It operates at a data rate of 33.3MHz with a maximum access time of 20ns. 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 housed in a 32-PLCC package (14x11.46mm) and is designed for surface mount installation. It supports operation across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous first-in-first-out memory architecture enabling independent read and write clock domains
• Integrated relay capability for signal buffering and timing adjustment
• Unidirectional data flow configuration optimized for specific interface requirements

Applications

• Data buffering between asynchronous logic systems
• Interface bridging in high-speed digital circuits
• Signal processing pipeline staging

Procurement Notes

Verify the part status carefully as this component is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary markets. Check for RoHS compliance status, which may be non-compliant for older batches. Ensure the 32-PLCC package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when a 512x9 asynchronous FIFO with 20ns access time is required. Consider the 32-PLCC package constraint for board layout. Evaluate if the unidirectional nature meets system data flow needs. Compare against newer alternatives if long-term supply stability is critical for the product lifecycle.

Part Context

This device belongs to the Renesas 7200 series of asynchronous FIFOs. It is manufactured by Renesas Electronics Corporation, formerly part of IDT. The 7201 variant specifically offers 4.5K depth. This series is designed for general-purpose memory buffering applications in industrial and commercial electronics.

Replacement Considerations

The 7201LA12JG is identified as an upgrade alternative from Renesas. Verify pin compatibility and electrical specifications before substitution.
