7205L12TP

Overview

The Renesas Electronics Corporation 7205L12TP is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 72K bits, organized as 8K words by 9 bits. It operates with a maximum data rate of 66.7 MHz and achieves a typical access time of 12 ns. The device functions within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. Designed for unidirectional bus applications, it utilizes a 28-pin PDIP package suitable for through-hole mounting. The component supports relay capability but lacks programmable flag support or First-Word-Fall-Through functionality.

Feature Summary

• Asynchronous operation enabling independent read and write clock domains
• Unidirectional data bus architecture for streamlined signal flow
• Integrated relay capability for enhanced signal integrity

Applications

• High-speed data buffering in communication systems
• Interface bridging between disparate logic families
• Data acquisition system temporary storage

Procurement Notes

Verify the specific suffix requirements against the official datasheet before ordering, as variations may exist. Confirm that the 28-PDIP package aligns with your PCB footprint constraints. Ensure the 4.5V to 5.5V supply voltage matches your system design. Check for end-of-life status or obsolescence notices from the manufacturer prior to finalizing procurement plans.

Selection Notes

Select this component when a high-speed asynchronous FIFO with 9-bit word width is required. The 12 ns access time suits applications demanding rapid data throughput. Consider the 28-pin DIP package if through-hole assembly is necessary. Verify that the unidirectional nature meets your interface requirements compared to bidirectional alternatives.

Part Context

This part belongs to the 7205 series of asynchronous FIFO memories manufactured by Renesas Electronics. The series typically offers various speed grades and organization options. The 7205L12TP specifically provides a balance of speed and density for general-purpose buffering tasks in industrial and commercial electronics.

Replacement Considerations

Consult the official replacement guide for direct substitutes. Cross-reference pinouts and electrical characteristics carefully. Ensure any alternative maintains the 9-bit data width and asynchronous operation mode.
