1 INTRODUCTION
The ST72324 devices are members of the ST7 mi-
crocontroller family designed for the 5V operating
range.
– The 32-pin devices are designed for mid-range
– The 42/44-pin devices target the same range of
For a description of the differences between
ST72324 and ST72324B devices refer to

All devices are based on a common industry-
standard 8-bit core, featuring an enhanced instruc-

tion set and are available with FLASH program
memory.
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 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.
