7200L12SOG

Overview

The Renesas Electronics Corporation 7200L12SOG is an asynchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 256 x 9 bits, providing 2 kbit of data buffering. The component supports a maximum clock frequency of 50 MHz with a typical access time of 12 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 80 mA. Designed for bidirectional data transfer, it utilizes a 28-pin SOIC package suitable for surface mount installation. The device functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Bidirectional bus direction supporting flexible data flow management
• Retransmit capability allowing read pointer reset via external pulse
• Hardware Full and Empty flags preventing data overflow and underflow

Applications

• Multiprocessing systems requiring asynchronous data exchange
• Rate buffer applications between mismatched speed interfaces
• Digital signal processing data buffering stages

Procurement Notes

Verify the specific suffix against official documentation, as standard listings often use 'SOG8' or 'SOGI8'. Confirm RoHS compliance status, as older variants may not meet current environmental regulations. Check for End-of-Life notices, as this part number family has faced discontinuation in certain configurations. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when bidirectional asynchronous buffering is required at speeds up to 50 MHz. The 256 x 9 organization suits applications needing moderate depth with 9-bit word widths. Consider the 28-SOIC package constraints for PCB layout. Verify that the 4.5V to 5.5V supply range aligns with the system power architecture before integration.

Part Context

This device is part of the Renesas 7200 series of dual-port FIFO memories. It shares architectural similarities with other members like the 7201LA and 7236 series but differs in speed, capacity, and directionality. The 7200L variant specifically targets general-purpose buffering needs with a balance of performance and pin count.

Replacement Considerations

Public confirmed substitute part numbers are not available for this specific discontinued configuration.
