GENERAL DESCRIPTION

INTRODUCTION
The ST72141K devices are members of the ST7 microcontroller family designed specifically for motor control applications and including A/D conversion and SPI interface capabilities. They include an on-chip Moter Controller peripheral for control of electric brushless moters with or without sensors. An example application, for 6-step control of a Permanent Magnet DC motor, is shown in Figure 1.
