TMS320C28344 (ACTIVE) Delfino™ 32-bit MCU with 300 MIPS, FPU, 260 KB RAM, EMIF



TMS320C2000™ 32-bit microcontrollers are optimized for processing, sensing, and actuation to improve closed-loop performance in real-time control applications. The C2000™ microcontrollers line includes the Delfino™ Premium Performance microcontroller family and the Piccolo™ Entry Performance microcontroller family.

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.
