ST7LITE0, ST7SUPERLITE

1 INTRODUCTION

The ST7LITE0 and ST7SUPERLITE are members

of the ST7 microcontroller family. All ST7 devices

are based on a common industry-standard 8-bit

core, featuring an enhanced instruction set.

The

ST7LITE0

and

ST7SUPERLITE

feature

FLASH memory with byte-by-byte In-Circuit Pro-

gramming (ICP) and In-Application Programming

(IAP) capability.

Under

software

control,

the

ST7LITE0

and

ST7SUPERLITE devices can be placed in WAIT,

SLOW, or HALT mode, reducing power consump-

tion 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 78.
