7200L12JG

Overview

The Renesas Electronics Corporation 7200L12JG is an asynchronous FIFO memory device with a storage capacity of 2.25K bits, organized as 256 words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 33.3 MHz with a 20 ns access time. The component features unidirectional bus directionality and includes retransmit capability for read pointer reset. It is housed in a 32-PLCC package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Retransmit (RT) capability allowing read pointer reset to initial position
• Full and Empty flags prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring asynchronous data transfer
• Rate buffering applications between mismatched clock domains
• Data communications interfaces needing temporary storage

Procurement Notes

Verify the specific suffix JG confirms the 32-pin PLCC package and commercial temperature grade. Confirm RoHS compliance status as historical documentation may vary. Check for obsolescence notices or PCNs affecting assembly location or labeling before finalizing procurement plans.

Selection Notes

Select this component when a 256x9 word depth is required for unidirectional asynchronous buffering. Ensure the system design accommodates the 33.3 MHz maximum frequency limit. Verify that the 32-PLCC surface mount package fits the PCB layout constraints and thermal requirements for the 0°C to 70°C operating environment.

Part Context

This part belongs to the 7200 series of CMOS parallel FIFOs manufactured by Renesas Electronics. It serves as a specialized memory interface solution for high-speed data handling tasks where precise flow control via Full/Empty flags is critical for system stability and data integrity.
