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.
