Product Introduction

Overview

The TMS320LF2402APGS, part of the TMS320C2000 platform, is a digital signal processor (DSP) controller from Texas Instruments. Although this specific model is now obsolete and no longer manufactured, it was designed for low-cost, low-power, and high-performance processing. The device is based on the TMS320C2xx DSP CPU core and is code-compatible with existing C24x DSP controllers, offering enhanced processing capabilities and a higher level of peripheral integration.
