7201LA12J

Overview

The Renesas Electronics Corporation 7201LA12J is an asynchronous FIFO memory device with a storage capacity of 4.5K (512 x 9). It operates at a data rate of 50MHz and features an access time of 12ns. The component supports unidirectional bus direction and includes relay capability. It functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum supply current of 80mA. The device is housed in a 32-PLCC package and is designed for surface mount installation.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Integrated relay capability for signal buffering
• Unidirectional data flow architecture

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status as legacy variants may differ. Check moisture sensitivity levels for proper handling during assembly. Ensure the PLCC-32 package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a 512-word by 9-bit depth is required for unidirectional data transfer. The 12ns access time suits high-speed applications up to 50MHz. Consider the 32-PLCC package for through-hole or specific surface-mount constraints. Verify power supply stability within the 4.5V to 5.5V range for optimal performance.

Part Context

This part belongs to the 7201L series of asynchronous FIFOs from Renesas Electronics. It shares architectural similarities with other members like the 7201LA12JG and IDT7201LA12JG. The series is designed for reliable data storage and transfer in complex digital systems requiring decoupled clock domains.

Replacement Considerations

The 7201LA12JG is listed as an upgrade replacement for discontinued variants in the same family. Verify pin compatibility and electrical specifications before substitution.
