1 INTRODUCTION

The ST7261 devices are members of the ST7 mi-

crocontroller family designed for USB applications.

All devices are based on a common industry-

standard 8-bit core, featuring an enhanced instruc-

tion set.

The ST7261 devices are ROM versions. The

FLASH version is supported by the ST72F623F2.

Under software control, all devices can be placed

in WAIT, SLOW, or HALT mode, reducing 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.
