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.
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.
