7202LA12JG

Overview

The Renesas Electronics Corporation 7202LA12JG is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K x 9. It operates at a data rate of 50MHz with a maximum access time of 12ns. The component supports unidirectional bus direction and includes retransmit 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 (32-LCC J-leads) measuring 14x11.46mm, designed for surface mount installation.

Feature Summary

• Asynchronous operation with independent read and write clock domains
• Retransmit capability for reliable data transfer
• CMOS parallel interface architecture

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as variants exist in tubes and reels. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 32-PLCC footprint matches your PCB design constraints. Check for any recent product change notices regarding labeling or assembly sites.

Selection Notes

Select this part when a 1K x 9 depth and 9-bit width are required for asynchronous buffering. Consider the 12ns access time and 50MHz speed against system timing requirements. Evaluate the 32-PLCC package availability against your manufacturing capabilities. Compare power consumption and operating temperature range with alternative FIFO solutions.

Part Context

This component belongs to the 7202L series of asynchronous FIFOs from Renesas Electronics. It shares architectural similarities with other parts in the family but differs in speed grade and packaging options. The 7202LA12JG specifically denotes the 12ns speed variant in a tube package.
