2 INTRODUCTION
The ST72334J/N-Auto, ST72314J/N-Auto and
ST72124J-Auto devices are members of the ST7
microcontroller family. They can be grouped as fol-
lows:
– ST72334J/N-Auto devices are designed for mid-
– ST72314J/N-Auto devices target the same
– ST72124J-Auto devices are for applications that
All devices are based on a common industry-
standard 8-bit core, featuring an enhanced instruc-
tion set.
The ST72C334J/N-Auto, ST72C314J/N-Auto and
ST72C124J-Auto versions feature single-voltage

Flash memory with byte-by-byte In-Situ Program-

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.
