STM32F051K4U7 Description

The STM32F051K4U7 microcontrollers have an ARM? Cortex?-M0 32-bit RISC CPU running at up to 48 MHz, high-speed embedded storage (up to 64 Kbytes of Flash memory and 8 Kbytes of SRAM), and a comprehensive set of upgraded peripherals and I/Os. Standard communication interfaces (up to two I2Cs, two SPIs, one I2S, one HDMI CEC, and up to two USARTs) are available on all devices, as well as one 12-bit ADC, one 12-bit DAC, six 16-bit timers, one 32-bit timer, and an advanced-control PWM timer.

STM32F051K4U7 Features

• VDD = 2.0 V to 3.6 V for digital and I/O supplies

• VDDA = from VDD to 3.6 V analog supply

• POR/PDR (power-on/power-down reset)

• Voltage detector that can be programmed (PVD)

• Sleep, Stop, and Standby are low-power modes with VBAT power for the RTC and backup registers.
