2 INTRODUCTION
The ST72334J/N, ST72314J/N and ST72124J de-
vices are members of the ST7 microcontroller fam-
ily. They can be grouped as follows:
– ST72334J/N devices are designed for mid-range
– ST72314J/N devices target the same range of
– ST72124J 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, ACTIVE-HALT 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.
