1 INTRODUCTION

The ST72321Mx Flash devices are members of

the ST7 microcontroller family 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 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.
