1 INTRODUCTION
The ST72F32A and ST7232A devices are mem-
bers of the ST7 microcontroller family designed for
the 5V operating range.
The 32 and 44-pin devices are designed for mid-
range applications
All devices are based on a common industry-
standard 8-bit core, featuring an enhanced instruc-
tion set and are available with FLASH or ROM pro-
gram 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.
