TMS320C28345ZFET

德尔菲诺微控制器 Delfino Microcontrollers

TMS320C2834x Delfino™ MCUs

Overview

The TMS320C2834x C2834x Delfino™ microcontroller MCU devices build on "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.
