1 INTRODUCTION

The ST72260G, ST72262G and ST72264G devic-

es are members of the ST7 microcontroller family.

They can be grouped as follows :

Under software control, all devices can be placed

in WAIT, SLOW, Active-HALT or HALT mode, re-

ducing power consumption when the application is

in idle or stand-by state.

– ST72264G devices are designed for mid-range

applications with ADC, I C and SCI interface ca-

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.

pabilities.

– ST72262G devices target the same range of ap-

plications but without I C interface or SCI.

– ST72160G devices are for applications that do

not need ADC, I C peripherals or SCI.

All devices are based on a common industry-

standard 8-bit core, featuring an enhanced instruc-

tion set.

The devices feature an on-chip Debug Module

(DM) to support in-circuit debugging (ICD). For a

description of the DM registers, refer to the ST7

ICC Protocol Reference Manual.

The ST72F160G, ST72F262G, and ST72F264G

versions feature single-voltage FLASH memory

with byte-by-byte In-Circuit Programming (ICP)

capabilities.
