Description

The STM32F031x4/x6 microcontrollers incorporate the high-performance

ARM® Cortex®-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speed

embedded memories (up to 32 Kbytes of Flash memory and 4 Kbytes of SRAM), and an

extensive range of enhanced peripherals and I/Os. All devices offer standard

communication interfaces (one I2C, one SPI/ I2S and one USART), one 12-bit ADC,

five 16-bit timers, one 32-bit timer and an advanced-control PWM timer.

The STM32F031x4/x6 microcontrollers operate in the -40 to +85 °C and -40 to +105 °C

temperature ranges, from a 2.0 to 3.6 V power supply. A comprehensive set of

power-saving modes allows the design of low-power applications.

The STM32F031x4/x6 microcontrollers include devices in six different packages ranging

from 20 pins to 48 pins with a die form also available upon request. Depending on the

device chosen, different sets of peripherals are included.

These features make the STM32F031x4/x6 microcontrollers suitable for a wide range of

applications such as application control and user interfaces, hand-held equipment, A/V

receivers and digital TV, PC peripherals, gaming and GPS platforms, industrial applications,

PLCs, inverters, printers, scanners, alarm systems, video intercoms and HVACs.
