16-bit, 5V Fixed-Point DSP - 'NRND' (Not Recommended for New Designs) - Technical Support Limited


This Product is no longer available

Replaced By TMS320C2802– The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.


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 us.
