Description

2 Description
The STM32F031x4/x6 microcontrollers incorporate the high-performance ARM
M0 32-bit RISC core operating at a 48 MHz maximum 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. The description below provides an
overview of the complete range of STM32F031x4/x6 peripherals proposed.
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.
