1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST72311R, ST72511R, and ST72532R devic-

es are members of the ST7 microcontroller family.

They can be grouped as follows:

– ST725xxR devices are designed for mid-range

applications with a CAN bus interface (Controller

Area Network). These devices are available in

OTP and EPROM versions only.

– ST72311R devices target the same range of ap-

plications but without the CAN interface. These

devices are available in ROM, OTP and EPROM

versions.

All devices are based on a common industry-

standard 8-bit core, featuring an enhanced instruc-

tion set.

Figure 1. Device Block Diagram

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.

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.
