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.
