1 INTRODUCTION
T(ShTe7LwITwEwS.SDTxa7)tLaaSITrheEee0mt4xeUm.cobmearnsd of
ST7SUPERLITE
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 82.
