Overview
The TMS320C6745CPTPD4 is a low-power digital signal processor (DSP) from Texas Instruments, based on the TMS320C674x DSP core. This device is part of the TMS320C6000™ platform and is designed to offer high processing performance while consuming significantly lower power compared to other members of the platform. It is ideal for original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to quickly develop and market devices requiring advanced signal processing capabilities.
