STMICROELECTRONICS  STM32L052R8T6  微控制器, 32位, 超低功率, ARM 皮质-M0+, 32 MHz, 64 KB, 8 KB, 64 引脚, LQFP

The is an ultra-low-power STM32 L0 series 32-bit Microcontroller incorporates the connectivity power of the universal serial bus USB 2.0 crystal-less with the high-performance ARM Cortex-M0+ RISC core operating at a 32MHz frequency. It features a memory protection unit MPU, high-speed embedded memories 64kB of Flash program memory, 2kB of data EEPROM and 8kB of RAM plus an extensive range of enhanced I/Os and peripherals. This device 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.
