1 INTRODUCTION
The ST72260G, ST72262G and ST72264G devic-
es are members of the ST7 microcontroller family.
They can be grouped as follows :
– ST72264G devices are designed for mid-range
– ST72262G devices target the same range of ap-
– ST72260G devices are for applications that do
All devices are based on a common industry-
standard 8-bit core, featuring an enhanced instruc-
tion set.
The ST72F260G, ST72F262G, and ST72F264G
versions feature single-voltage FLASH memory

capabilities.
Under software control, all devices can be placed
in WAIT, SLOW, Active-HALT or HALT mode, re-
ducing 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.
