NUCLEO-L053R8开发板主要特性,框图,电路图,材料清单和PCB设计文件.?The ultra-low-power STM32L053x6/8 are offered in 3 different package types: from 48 pins to 64 pins. Depending on the device chosen, different sets of peripherals are included, the description below gives an overview of the complete range of peripherals proposed in this family. These features make the ultra-low-power STM32L053x6/8 microcontrollers suitable for a wide range of applications:?? Gas/water meters and industrial sensors?? Healthcare and fitness equipment?? Remote control and user interface?? PC peripherals, gaming, GPS equipment?? Alarm system, wired and wireless sensors, video intercom?The ultra-low-power STM32L053x6/8 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 64 Kbytes of Flash program memory, 2 Kbytes of data EEPROM and 8 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals. The STM32L053x6/8 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 STM32L053x6/8 devices offer several analog features, one 12-bit ADC with hardware oversampling, one DAC, two ultra-low-power comparators, several timers, one low-power timer (LPTIM), three general-purpose 16-bit timers and one 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
