description
The TMS320C5x generation of the Texas Instruments (TITM) TMS320 digital signal processors (DSPs) is fabricated with static CMOS integrated circuit technology; the architectural design is based upon that of an earlier TI DSP, the TMS320C25. The combination of advanced Harvard architecture, on-chip peripherals, on-chip memory, and a highly specialized instruction set is the basis of the operational flexibility and speed of the ’C5x‡ devices. They execute up to 50 million instructions per second (MIPS).
The ’C5x devices offer these advantages:
TMS320C50, TMS320LC50, TMS320C51, TMS320LC51, TMS320C53, TMS320LC53

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 3: All voltage values are with respect to VSS.

‡ This IOH can be exceeded when using a 1-kΩ pulldown resistor on the TDM serial port TADD output; however, this output still meets VOH specifications under these conditions.
