Product overview

Description

The STM32F051xx 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 64 Kbytes of Flash memory and 8 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, one I2S, one HDMI CEC and up to two USARTs), one 12-bit ADC, one 12-bit DAC, six 16-bit timers, one 32-bit timer and an advanced-control PWM timer.

The STM32F051xx 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 STM32F051xx microcontrollers include devices in seven different packages ranging from 32 pins to 64 pins with a die form also available upon request. Depending on the device chosen, 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, 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.
