1 INTRODUCTION

The ST7234x devices are members of the ST7 mi-

crocontroller family. All devices are based on a

common industry-standard 8-bit core, featuring an

enhanced instruction set.

They feature single-voltage FLASH memory with

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

Application Programming (IAP) capabilities.

Under software control, all devices can be placed

in WAIT, SLOW, Auto-Wakeup from Halt, Active-

HALT or HALT mode, reducing power consump-

tion 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.

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.
