DESCRIPTION

The PT2581 incorporates the high-performance ARM

frequency and high-speed embedded memories (32k-

bytes Flash memory, 8k-bytes SRAM and 6k-bytes

ROM).The PT2581 is core processor specifically

designed for motor control. The PT2581 integrates a

configurable processing core and peripheral circuits

to perform FOC and Sensor-less motor control.

System

control,

user

interface,

communication

interface and I/O interface can be programmed

through the embedded ARM-M0 for different motor

applications.

PT2581 offers standard communication interfaces

(the 3 channels for Bias-PGA, and the 3 channels for

PGA and Comparator), six general-purpose 16-bit/32-

bit timers, and six PWM channels. This approach

reduces the software burden and simplifies the

control system program because complex motor

control algorithms are executed in the PT2581.
