STM32L011F4P6 Description
The high-performance Arm? Cortex?-M0+ 32-bit RISC core, which operates at a 32 MHz frequency, is included in the access line ultra-low-powerSTM32L011F4P6 family along with high-speed embedded memories (up to 16 Kbytes of Flash program memory, 512 bytes of data EEPROM, and 2 Kbytes of RAM), a wide variety of enhanced I/Os, and peripherals.
High power efficiency is offered by the STM32L011F4P6 device for a variety of performances. A wide variety of internal and external clock sources, an internal voltage adaption, and numerous low-power modes are used to achieve it.
The STM32L011F4P6 device has a number of analog capabilities, including a 12-bit ADC with hardware oversampling, two comparators that consume very little power, multiple timers, a low-power timer (LPTIM), three general-purpose 16-bit timers, an RTC, and a SysTick that can serve as a timebase. They also have two watchdogs: a window watchdog based on bus clock and a watchdog with separate clock and window functionality.
The STM32L011F4P6 device also includes one I2C, one SPI, one USART, and a low-power UART among other advanced and conventional communication interfaces.
Additionally, the STM32L011F4P6 has a real-time clock and a group of backup registers that are powered while the device is in Standby mode.
The STM32L011F4P6 ultra-low-power device can run on a 1.8 to 3.6 V power supply with BOR or a 1.65 to 3.6 V power supply without BOR option (down to 1.65 V at power down). They are offered in the temperature range of -40 to +125 °C. The development of low-power applications is made possible by a wide range of power-saving modes.
