ST10F272M-4QR3

16位MCU采用256字节的闪存和20 KB的RAM 16-bit MCU with 256 Kbyte Flash memory and 20 Kbyte RAM

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
