description
The TMS320C242 device is a member of the ’24x family of digital signal processor (DSP) controllers based on
the TMS320C2xx generation of 16-bit fixed-point DSPs. The TMS320F241 device is fully compatible with the
’C242 to allow emulation during prototype development. (These two devices share similar core and
peripherals.) This new family is optimized for digital motor / motion control applications. The DSP controllers
combine the enhanced TMS320 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.
