1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The ST72141K devices are members of the ST7
microcontroller family designed specifically for mo-
tor control applications and including A/D conver-
sion and SPI interface capabilities. They include
an on-chip Moter Controller peripheral for control
of electric brushless moters with or without sen-
sors. An example application, for 6-step control of
a Permanent Magnet DC motor, is shown in Figure
1.
The ST72141K devices are based on a common
industry-standard 8-bit core, featuring an en-
hanced instruction set.
Under software control, they can be placed in
WAIT, SLOW, or HALT mode, reducing power
consumption when the application is in idle or
standby state.
The enhanced instruction set and addressing
modes of the ST7 offer both power and flexibility to
software developers, enabling the design of highly
efficient and compact application code. In addition
to standard 8-bit data management, all ST7 micro-
controllers feature true bit manipulation, 8x8 un-
signed multiplication and indirect addressing
modes.
