description
The TMS320C242 device is a member of the TMS320 DSP family of digital signal processor (DSP) controllers
based on the TMS320C2xx generation of 16-bit fixed-point DSPs. This new generation is optimized for digital
motor/motion control applications. The DSP controllers combine the enhanced TMS320 DSP family
architectural design of the C2xx core CPU for low-cost, high-performance processing capabilities and several
advanced peripherals optimized for motor/motion control applications. These peripherals include the event
manager module, which provides general-purpose timers and PWM registers to generate PWM outputs, and
a single,10-bit analog-to-digital converter (ADC), which can perform conversion within 1 µs.
