1 DESCRIPTION
The ST72F325 Flash and ST72325 ROM devices
are members of the ST7 microcontroller family de-
signed for mid-range applications.
They are derivatives of the ST72321 and ST72324
devices, with enhanced characteristics and robust
Clock Security System.
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, I
For power economy, microcontroller can switch
dynamically into WAIT, SLOW, ACTIVE-HALT or

Main Differences with ST72321:
– LQFP48 and LQFP32 packages
– Clock Security System
– Internal RC, Readout protection, LVD and PLL
– Negative current injection not allowed on I/O port
– External interrupts have Exit from Active Halt
