4.1 STM32F030R8T6 microcontroller
The STM32F030R8T6 microcontroller incorporates the high-performance ARM
Cortex™-M0 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded
memories (up to 64 Kbytes of Flash memory and up to 8 Kbytes of SRAM), and an
extensive range of enhanced peripherals and I/Os. All devices offer standard
communication interfaces (up to two I
12-bit ADC, up to 6 general-purpose 16-bit timers and an advanced-control PWM timer.
Figure 5. STM32F030R8T6 package
The STM32F030R8T6 microcontroller operates in the -40 to +85 °C temperature range,
from a 2.4 V to 3.6 V power supply. A comprehensive set of power-saving modes allows the
design of low-power applications.
