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.
