Description for the TMS320C28346
The TMS320C2834x (C2834x) Delfino™ microcontroller unit (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.
The TMS320C28346, TMS320C28345, TMS320C28344, TMS320C28343, TMS320C28342, and TMS320C28341 devices, members of the Delfino™ MCU generation, are highly integrated, high-performance solutions for demanding control applications.
Throughout this document, the devices are abbreviated as C28346, C28345, C28344, C28343, C28342, and C28341, respectively. Device Comparison provides a summary of features for each device.
