STM32F051R4T6TR a 32-bit microcontroller MCU/ST [Copy link]

Description
The STM32F051xx microcontrollers integrate a high-performance ARM Cortex -M0 32-bit RISC core operating at up to 48 MHz, high-speed embedded memories (up to 64k bytes of Flash and 8k bytes of SRAM), and a wide range of enhanced peripherals and I/Os. All devices offer standard communication interfaces (up to two I2Cs, up to two SPIs, one I2S, one HDMI CEC, and up to two USARTs), a 12-bit ADC, a 12-bit DAC, six 16-bit timers, one 32-bit timer, and one advanced control PWM timer. The
STM32F051xx microcontrollers operate over the temperature range of -40 to +85°C and -40 to +105°C with a supply voltage of 2.0 to 3.6 V. A comprehensive set of power-saving modes supports the design of low-power applications. The
STM32F051xx microcontrollers include devices in seven different packages, from 32 to 64 pins, and are also available in chip form on request. Depending on the device selected, different sets of peripherals are included.
These features make the STM32F051xx microcontrollers suitable for a wide range of applications such as application control and user interfaces, handheld devices, A/V receivers and digital TVs, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms and HVACs.
