TMS320DM6446ZWT

Product Summary

The TMS320DM6446ZWT is a Digital Media System-on-Chip. The TMS320DM6446ZWT leverages TI’s DaVinci technology to meet the networked media encode and decode application processing needs of next-generation embedded devices. The TMS320DM6446ZWT enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, high processing performance, and long battery life through the maximum flexibility of a fully integrated mixed processor solution. The dual-core architecture of the device provides benefits of both DSP and Reduced Instruction Set Computer (RISC) technologies, incorporating a high-performance TMS320C64x+ DSP core and an ARM926EJ-S core.
