description  
The TMS320C2xx generation of digital signal processors (DSPs) combines strong performance and great  
flexibility to meet the needs of signal processing and control applications. The T320C2xLP core CPU that is the  
basis of all ’C2xx devices has been optimized for high speed, small size, and low-power, making it ideal for  
demanding applications in many markets. The CPU has an advanced, modified Harvard architecture with six  
internal buses that permits tremendous parallelism and data throughput. The powerful ’C2xx instruction set  
makes software development easy. And because the ’C2xx is code-compatible with the TMS320C2x and ’C5x  
generations, your code investment is preserved. Around this core, ’C2xx-generation devices feature various  
combinations of on-chip memory and peripherals. The serial ports provide easy communication with external  
devices such as codecs, A/D converters, and other processors. Other peripherals that facilitate the control of  
external devices include general-purpose I/O pins, a 20-bit timer, and a wait-state generator.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
