7201LA20TDB

Overview

The Renesas Electronics Corporation 7201LA20TDB is an asynchronous FIFO memory integrated circuit manufactured by Renesas. It features a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The device supports unidirectional data bus direction and operates with a maximum data rate of 33.3MHz. It has a typical access time of 20ns and functions within a supply voltage range of 4.5V to 5.5V. The component is housed in a 28-CDIP package and is designed for surface mount installation. It operates within a temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation mode for independent read and write clock domains
• Unidirectional data flow capability for specific interface requirements
• CMOS technology implementation for parallel FIFO functionality

Applications

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

Procurement Notes

Verify the exact package type and pinout configuration against the official datasheet before integration, as CDIP variants may differ from PLCC versions within the same series. Confirm that the 0°C to 70°C commercial temperature range meets your system's environmental requirements. Ensure power supply stability within the 4.5V to 5.5V range to maintain the specified 20ns access time and 33.3MHz data rate performance.

Selection Notes

Select this component when asynchronous buffering with a 9-bit word width is required. Compare against other members of the 7201L series if different access times or package styles are needed. Verify that the unidirectional nature aligns with your data flow architecture. Consider thermal management capabilities within the commercial temperature grade for your specific enclosure design.

Part Context

This part belongs to the Renesas 7201L series of asynchronous FIFO memories. It shares functional similarities with other devices in the family but differs in package style and specific timing characteristics. The 7201L series is designed for general-purpose data buffering applications requiring reliable asynchronous operation between digital subsystems.

Replacement Considerations

Check for direct cross-reference part numbers from IDT or Renesas that share the same electrical specifications and pinout compatibility. Verify that any substitute maintains the 9-bit data width and asynchronous operation mode.
