7205L30TDB

Overview

The Renesas Electronics Corporation 7205L30TDB is an asynchronous FIFO memory device with a storage capacity of 72K bits, organized as 8K words by 9 bits. It operates at a maximum data rate of 25MHz with an access time of 30ns. The component supports unidirectional bus operation and functions within a supply voltage range of 4.5V to 5.5V. Maximum supply current is specified at 150mA. It is housed in a 28-CDIP package and is designed for industrial temperature ranges.

Feature Summary

• Asynchronous dual-port architecture enabling independent read and write clock domains
• Hardware-based Full and Empty flags to manage data flow and prevent overflow or underflow conditions
• Uni-directional bus configuration for dedicated input and output paths

Applications

• Data buffering between components operating at different clock speeds
• Interface bridging in high-speed digital signal processing systems
• Temporary data storage in communication protocol converters

Procurement Notes

Verify the specific suffix TDB against official Renesas documentation to confirm package type and electrical characteristics. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for End-of-Life notices or obsolescence warnings before finalizing procurement plans. Ensure compatibility with existing board layouts for the 28-CDIP footprint.

Selection Notes

Select this component when an asynchronous interface with 9-bit word width is required. The 30ns access time suits moderate-speed applications. Verify that the 150mA current consumption fits the system power budget. Ensure the design accommodates the unidirectional bus constraint and utilizes the hardware flags for flow control rather than software polling.

Part Context

This part belongs to the 7205 series of CMOS FIFO memories manufactured by Renesas Electronics. The series provides various speed grades and configurations for parallel data transfer applications. The 7205L30TDB specifically represents the 30ns speed grade variant within this family, offering a balance of performance and integration for standard logic interfaces.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully. Generic FIFO replacements may lack compatible flag logic or voltage tolerances.
