Motorola DSP Advantages and Features
2.
2
The Motorola DSP56F80x family is well suited for digital motor control, combining the DSP’s
calculation capability with the MCU’s controller features on a single chip. These DSPs offer many
dedicated peripherals, such as Pulse Width Modulation (PWM) module(s), an Analog-to-Digital
Converter (ADC), Timers, communication peripherals (SCI, SPI, CAN), on-board Flash and RAM.
As an example, one member of the family, the DSP56F805, provides the following peripheral blocks:
In addition to the fast Analog-to-Digital converter and the 16-bit Quadrature Timers, the most
interesting peripheral, from the PM synchronous motor control point of view, is the Pulse Width
Modulation (PWM) module. The PWM module offers a high degree of freedom in its configuration,
allowing efficient control of the PM synchronous motor.
