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 5V to 1.8V on-chip voltage regulator. The part is supplied with a single 5V supply and I/Os work at 5V.
The ST10F272M is an optimized version of the ST10F272E, upward compatible with the following set of differences:

● Maximum CPU frequency is 40 MHz
● Reduced range for the Standby Voltage: VStby must be in the range of 4.5 to 5.5V.
● 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 5V for the ballast transistors
