STMicroelectronics, Inc. Microcontrollers STM32L071KBU3TR

The STM32L071KBU3TR is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at frequencies up to 32 MHz. It features a power supply range of 1.65 V to 3.6 V and is designed for applications requiring low power consumption, with standby current as low as 0.29 µA and a wakeup time of 5 µs from Flash memory. The device includes up to 192 KB of Flash memory, 20 KB of SRAM, and 6 KB of EEPROM, all with error correction code (ECC) support. This microcontroller is equipped with a rich set of peripherals, including a 12-bit ADC capable of 1.14 Msps with up to 16 channels, multiple communication interfaces such as USART, UART, SPI, and I2C, and a 7-channel DMA controller. It also supports various timers, including two 16-bit timers with multiple channels, a real-time clock (RTC), and watchdog timers. The STM32L071KBU3TR is available in several package options, including LQFP and WLCSP, and is compliant with ECOPACK2 standards. This combination of features makes it suitable for battery-operated devices and other applications where power efficiency is critical.
