Introduction
Description
The ST10F272M device is a new derivative of the STMicroelectronics ST10 family of 16-bit
single-chip CMOS microcontrollers.
The ST10F272M combines high CPU performance (up to 20 million instructions per second)
with high peripheral functionality and enhanced I/O capabilities. It also provides on-chip
high-speed single voltage Flash memory, on-chip high-speed RAM, and clock generation
via PLL.
The ST10F272M is processed in 0.18mm CMOS technology. The MCU core and the logic is
supplied with a 5 V to 1.8 V on-chip voltage regulator. The part is supplied with a single 5 V
supply and I/Os work at 5 V.
The ST10F272M is an optimized version of the ST10F272E, upward compatible with the
following set of differences:

Special characteristics
1.2.1 X-peripheral clock gating
This new feature have been implemented on the ST10F272M: Once the EINIT instruction
has been executed, only the X-peripherals enabled in the XPERCON register will be
clocked.
The new feature allows to reduce the power consumption and also should improve the
emissions as it avoids to propagate useless clock signals across the device.
1.2.2 Improved supply ring
An RC filter has been introduced in the 5 V power supply ring of the ballast transistor. In
addition, the supply rings for the internal voltage regulators and the I/Os have been split.
These two modifications should improve the behavior of the device regarding conducted
emissions.
Maximum CPU frequency is 40 MHz
Reduced range for the Standby Voltage: V
Identification registers: the IDMEM register reflects the Flash type difference and can
be used to differentiate the two devices by software
Improved EMC behavior thanks to the introduction of an internal RC filter on the 5 V for
the ballast transistors
Stby
must be in the range of 4.5 to 5.5 V.
