ST7LITE1xB

1 INTRODUCTION

The ST7LITE1xB is a member of the ST7 micro-

controller family. All ST7 devices are based on a

common industry-standard 8-bit core, featuring an

enhanced instruction set.

The ST7LITE1xB features FLASH memory with

byte-by-byte In-Circuit Programming (ICP) and In-

Application Programming (IAP) capability.

Under software control, the ST7LITE1xB device

can be placed in WAIT, SLOW, or HALT mode, re-

ducing power consumption 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 110. The ST7LITE1xB fea-

tures 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.
