The ADMC401BSTZ is a single-chip DSP-based high performance Motor Controller for control of AC induction motors (ACIM), permanent magnet synchronous motors (PMSM), brushless DC motors (BDCM) and switched reluctance (SR) motors in industrial applications. The ADMC401 integrates a 26 MIPS, fixed-point DSP core with a complete set of motor control peripherals that permits fast motor control in a highly integrated environment. The DSP core of the ADMC401 is the ADSP-2171 which is completely code compatible with the ADSP-21xx DSP family and combines three computational units, data address generators and a program sequencer. The computational units comprise an ALU, a multiplier/accumulator (MAC) and a barrel shifter. The DSP core also adds instructions for bit manipulation, squaring (x2), biased rounding and global interrupt masking. In addition, two flexible double-buffered, bidirectional synchronous serial ports are included in the ADMC401.
