ST10F273M-4T3 STMicroelectronics 16bit MCU

ST10F273M-4T3 Overview

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.
