ST10F273M
1 Introduction
Introduction
1.1 Description
The ST10F273M device is a new derivative of the STMicroelectronics® ST10 family of 16-bit
single-chip CMOS microcontrollers.
The ST10F273M 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 ST10F273M is processed in 0.18mm CMOS technology. The MCU core and the logic is
supplied with a 5V to 1.8V on-chip voltage regulator. The part is supplied with a single 5V
supply and I/Os work at 5V.
The ST10F273M is an optimized version of the ST10F273E, upward compatible with the
following set of differences:
● Maximum CPU frequency is 40 MHz
● A single bank of IFlash has been implemented but the programming interface has been
kept compatible with the ST10F273E
● Identification registers: the IDMEM register reflects the Flash type difference and allows
to differentiate the two devices by software
● Improved EMC behavior thanks to the introduction of an internal RC filter on the 5V for
the ballast transistors
● The clock to the X-Peripherals is gated: X-Peripheral not used will not get the clock in
order to reduce the power consumption.

1.2.2
Special characteristics
X-Peripheral clock gating
This new feature have been implemented on the ST10F273M: 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.
Improved supply ring
An RC filter has been introduced in the 5V power supply ring of the ballast transistor. In
addition, the supply rings for the internal voltage regulators and the IOs have been split.
These two modifications should improve the behavior of the device regarding conducted
emissions.
