1 INTRODUCTION
The ST72104G, ST72215G, ST72216G and
ST72254G devices are members of the ST7 mi-
crocontroller family. They can be grouped as fol-
lows:
– ST72254G devices are designed for mid-range
– ST72215/6G devices target the same range of
– ST72104G devices are for applications that do
All devices are based on a common industry-
standard 8-bit core, featuring an enhanced instruc-
tion set.

Under software control, all devices can be placed
in WAIT, SLOW, or HALT mode, reducing power
consumption when the application is in idle or
stand-by 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.
