3.3V DSP for Digital Motor Control
Zhenyu Yu C2000 Applications

Abstract
New generations of motor control digital signal processors (DSPs) lower their supply voltages
from 5V to 3.3V to offer higher performance at lower cost. Replacing traditional 5V digital control
circuitry by 3.3V designs introduce no additional system cost and no significant complication in
interfacing with TTL and CMOS compatible components, as well as with mixed voltage ICs such
as power transistor gate drivers. Just like 5V based designs, good engineer
