ST7FLITE2
1 INTRODUCTION
The ST7FLITE2 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 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.
The ST7FLITE2 features FLASH memory with
byte-by-byte In-Circuit Programming (ICP) and In-
Application Programming (IAP) capability.
Under software control, the ST7FLITE2 device
can be placed in WAIT, SLOW, or HALT mode, re-
ducing power consumption when the application is
in idle or standby state.
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.
