STMICROELECTRONICS  STM32L152QEH6  微控制器, 32位, 超低功率, ARM 皮质-M3, 32 MHz, 512 KB, 80 KB, 132 引脚, UFBGA

The is an ultra-low-power STM32 L1 series 32-bit Microcontroller incorporates the connectivity power of the universal serial bus USB with the high-performance ARM Cortex-M3 RISC core operating at a frequency of 32MHz 33.3 DMIPS. It features a memory protection unit MPU, high-speed embedded memories Flash memory up to 512kB and RAM up to 80KB and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer two operational amplifiers, one 12-bit ADC, two DACs, two ultra-low-power comparators, one general-purpose 32-bit timer, six general-purpose 16-bit timers and two basic timers, which can be used as time bases. The device contain standard and advanced communication interfaces - two I²Cs, two I²Ss, three SPIs, three USARTs, two UARTs and an USB.
