STMICROELECTRONICS STM32L072RBT6 微控制器, 32位, 超低功率, ARM 皮质-M0+, 32 MHz, 128 KB, 20 KB, 64 引脚, LQFP
The ultra-low-power STM32L072xx microcontrollers incorporate the connectivity power of the universal serial bus USB 2.0 crystal-less with the high-performance ARM® Cortex®-M0+ 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit MPU, high-speed embedded memories up to 192 Kbytes of Flash program memory, 6 Kbytes of data EEPROM and 20 Kbytes of RAM plus an extensive range of enhanced I/Os and peripherals.
The STM32L072xx devices provide high power efficiency for a wide range of performance. It is achieved with a large choice of internal and external clock sources, an internal voltage adaptation and several low-power modes.
The STM32L072xx devices offer several analog features, one 12-bit ADC with hardware oversampling, two DACs, two ultra-low-power comparators, AES, several timers, one low-power timer LPTIM, four general-purpose 16-bit timers and two basic timer, one RTC and one SysTick which can be used as timebases. They also feature two watchdogs, one watchdog with independent clock and window capability and one window watchdog based on bus clock.
Moreover, the STM32L072xx devices embed standard and advanced communication interfaces: up to three I2Cs, two SPIs, one I2S, four USARTs, a low-power UART LPUART, and a crystal-less USB. The devices offer up to 1924 capacitive sensing channels to simply add touch sensing functionality to any application.
The STM32L072xx also include a real-time clock and a set of backup registers that remain powered in Standby mode.
The ultra-low-power STM32L072xx devices operate from a 1.8 to 3.6 V power supply down to 1.65 V at power down with BOR and from a 1.65 to 3.6 V power supply without BOR option. They are available in the -40 to +125 °C temperature range. A comprehensive set of power-saving modes allows the design of low-power applications.
