1 DESCRIPTION

The

ST7LITE0x

and

ST7SUPERLITE

(ST7LITESx) are members 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 ST7LITE0x and ST7SUPERLITE feature

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

gramming (ICP) and In-Application Programming

(IAP) capability.

Under software control, the ST7LITE0x 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 81.
