7202LA50J

Overview

The Renesas Electronics Corporation 7202LA50J is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 50 ns. The component supports a data rate of up to 20 MHz and draws a maximum supply current of 80 mA. It utilizes a unidirectional bus direction and is housed in a 32-PLCC package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow capability
• CMOS technology construction

Applications

• Data buffering between different clock domains
• Interface bridging in parallel communication systems
• Temporary data storage in high-speed digital circuits

Procurement Notes

Verify the specific suffix 'J' against official Renesas documentation to confirm package type and RoHS compliance status. Confirm availability as this part may be subject to discontinuation or limited stock. Ensure the required lead times align with production schedules before finalizing procurement orders.

Selection Notes

Select this component when a 1K x 9 asynchronous FIFO is required with a 50 ns access time. Consider the 32-PLCC package constraints for PCB layout. Verify that the 4.5 V to 5.5 V operating voltage matches the system power rails and that unidirectional data transfer meets the application requirements.

Part Context

This device belongs to the 7202L series of CMOS asynchronous FIFOs manufactured by Renesas Electronics. It is designed for general-purpose data buffering applications requiring moderate speed and standard parallel interfaces. The series typically offers various speed grades and package options to suit different design needs.

Replacement Considerations

Check for direct substitutes such as IDT7202LA50J or other 7202L series variants with compatible pinouts and electrical specifications. Ensure any replacement maintains the same 1K x 9 depth and 50 ns access time.
