1 INTRODUCTION

The ST72F321 and ST72321 devices are mem-

bers 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 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.
