Overview
The TMS320C6742BZCEA2 is a fixed- and floating-point Digital Signal Processor (DSP) from Texas Instruments, based on the C674x DSP core. This low-power applications processor is designed to provide high performance with significantly lower power consumption compared to other members of the TMS320C6000 platform. It is ideal for original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to develop devices with robust operating systems, rich user interfaces, and high processor performance.
