1 DESCRIPTION
The ST72F324L and ST72324BL devices are
members of the ST7 microcontroller family de-
signed for mid-range applications running at 3.3V.
Different package options offer up to 32 I/O pins.
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,
2 general purpose timers, an SPI interface and an
SCI interface.
For power economy, microcontroller can switch
dynamically into WAIT, SLOW, ACTIVE-HALT or
HALT mode when the application is in idle or
stand-by state.
Typical applications are consumer, home, office
and industrial products.
