GENERAL DESCRIPTION

INTRODUCTION

The ST72311R, ST72511R, ST72512R and ST72532R devices are members of the ST7 microcontroller family. They can be grouped as follows:

– ST725xxR devices are designed for mid-range applications witha CAN bus interface Controller Area Network

– ST72311R devices target the same range of applications but without CAN interface.

All devices are based on a common industry standard 8-bit core, featuring an enhanced instruction set.

Under software control, all devices can be placed in WAIT, SLOW, ACTIVE-HALT or HALT mode, reducing power consumption when the application is in idle or standby state.
