Procurement Notes

The ASC8849AETK is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current supply status and alternative sourcing strategies is required before procurement planning.

Selection Notes

Select this component for applications requiring dedicated H.264 decoding at 720p resolution with ARM926EJ-S compatibility. Ensure design support for the TFBGA-484 package and verify interface requirements for Ethernet, I2S, SPI, UART, and Video connections match the system architecture.

Part Context

This part belongs to NXP's specialized application processor family, distinct from general-purpose microcontrollers. It shares the TFBGA-484 package form factor with related models like the ASC8848AETK but differs in core clock speed (500 MHz vs 400 MHz) and specific video processing throughput specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineering evaluation of pin-compatible alternatives or redesign for newer NXP video processors is necessary.
