Description
The STM32F071x8/xB 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 128 Kbytes of Flash memory and 16 Kbytes of SRAM), and an extensive range of
enhanced peripherals and I/Os. All devices offer standard communication interfaces (two
I2Cs, two SPI/one I2S, one HDMI CEC and four USARTs), one 12-bit ADC, one 12-bit DAC
with two channels, seven 16-bit timers, one 32-bit timer and an advanced-control PWM
timer.
The STM32F071x8/xB 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 STM32F071x8/xB microcontrollers include devices in six different packages ranging
from 48 pins to 100 pins with a die form also available upon request. Depending on the
device chosen, different sets of peripherals are included.
These features make the STM32F071x8/xB 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.
