TMS320C242 (OBSOLETE)

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.

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 us.
