ARM-based 32-bit MCU, 48MHz

The STM32F070xB/6 microcontrollers incorporate the high-performance ARM Cortex -M0 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (up to 128 Kbytes of Flash memory and up to 16 Kbytes of SRAM), and an extensive range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (up to two I²Cs, up to two SPIs and up to four USARTs), one USB Full speed device, one 12-bit ADC, seven general-purpose 16-bit timers and an advanced-control PWM timer.The STM32F070xB/6 microcontrollers operate in the -40 to +85 °C temperature range from a 2.4 to 3.6V power supply. A comprehensive set of power-saving modes allows the design of low-power applications.The STM32F070xB/6 microcontrollers include devices in three different packages ranging from 20 pins to 64 pins. Depending on the device chosen, different sets of peripherals are included. The description below provides an overview of the complete range of STM32F070xB/6 peripherals proposed.These features make the STM32F070xB/6 microcontrollers suitable for a wide range of applications such as application control and user interfaces, handheld 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.
