●TMS320C2834x ( Delfino™) MCUs
●Overview
●The TMS320C2834x (C2834x) Delfino™ microcontroller (MCU) devices build on TI"s existing F2833x high-performance floating-point microcontrollers. The C2834x delivers up to 300 MHz of floating-point
●performance, and has up to 516KB of on-chip RAM. Designed for real-time control applications, the
●C2834x is based on the C28x™ core, making it code-compatible with all C28x microcontrollers. The on-chip peripherals and low-latency core make the C2834x an excellent solution for performance-hungry real-time control applications.
