1 DESCRIPTION

The ST72361 devices are members of the ST7 mi-

crocontroller family designed for mid-range appli-

cations with LIN (Local Interconnect Network) in-

terface.

All devices are based on a common industry-

standard 8-bit core, featuring an enhanced instruc-

tion set and are available with Flash or ROM pro-

gram memory. The ST7 family architecture offers

both power and flexibility to software developers,

enabling the design of highly efficient and compact

application code.

The on-chip peripherals include an A/D converter,

a PWM Autoreload timer, 2 general purpose tim-

ers, 2 asynchronous serial interfaces, and an SPI

interface.

For power economy, microcontroller can switch

dynamically into WAIT, SLOW, Active-Halt, Auto

Wake-up from HALT (AWU) or HALT mode when

the application is in idle or stand-by state.

Typical applications are consumer, home, office

and industrial products.
