TW9921AT-NA1-GR

Overview

The TW9921AT-NA1-GR is a video decoder integrated circuit manufactured by Renesas Electronics Corporation. It supports NTSC and PAL analog video standards for consumer video applications. The device utilizes an I2C control interface for configuration. It operates with dual power supplies of 1.8V and 3.3V. The component is housed in a 32-VFQFN package with exposed pad, specifically the 32-QFN (5x5) form factor. It features surface mount installation with wettable flanks to ensure reliable solder joint inspection.

Feature Summary

• Supports NTSC and PAL analog video decoding standards
• Utilizes I2C serial control interface for system integration
• Features wettable flank package design for enhanced solder joint visibility

Applications

• Consumer video equipment
• Analog video signal processing systems
• Video decoder modules

Procurement Notes

Verify the specific suffix AT-NA1-GR against official Renesas documentation to confirm the inclusion of wettable flank technology and exact pinout compatibility. Ensure that the required 1.8V and 3.3V power domains are correctly implemented in the target design. Confirm RoHS compliance status through the manufacturer's current environmental declaration before final procurement approval.

Selection Notes

Select this component when NTSC or PAL video decoding is required with high reliability soldering standards. The wettable flank feature distinguishes it from standard QFN packages by allowing automated optical inspection of side solder joints. Verify that the I2C interface matches the host controller capabilities and that the dual voltage supply architecture fits the system power budget constraints.

Part Context

This part belongs to the Renesas TW99xx series of video decoders. It is functionally related to other models such as the TW9992 and TW9900 within the same product family. These components share similar application domains in consumer video processing but may differ in supported standards, package types, or specific feature sets. Cross-referencing should be performed carefully based on datasheet specifications.

Replacement Considerations

Official substitute part numbers must be confirmed via Renesas cross-reference tools. Generic equivalents are not verified. Check for identical package dimensions and pin assignments if substituting with other TW99xx variants.
