1 INTRODUCTION

The ST7LITE3 is a member of the ST7 microcon-

troller family. All ST7 devices are based on a com-

mon industry-standard 8-bit core, featuring an en-

hanced instruction set.

The ST7LITE3 features FLASH memory with

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

Application Programming (IAP) capability.

Under software control, the ST7LITE3 device can

be placed in WAIT, SLOW, or HALT mode, reduc-

ing power consumption when the application is in

idle or standby 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.

For easy reference, all parametric data are located

in section 13 on page 131.

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.
