STMICROELECTRONICS STM32L151UCY7TR 微控制器, 32位, ARM 皮质-M3, 32 MHz, 128 KB, 32 KB, 48 引脚, UFQFPN
The ultra-low-power STM32L151xC and STM32L152xC devices incorporate the connectivity power of the universal serial bus USB with the high-performance ARM® Cortex®-M3 32-bit RISC core operating at a frequency of 32 MHz 33.3 DMIPS, a memory protection unit MPU, high-speed embedded memories Flash memory up to 256 Kbytes and RAM up to 32 Kbytes and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
The STM32L151xC and STM32L152xC 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.
Moreover, the STM32L151xC and STM32L152xC devices contain standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2S, three USARTs and an USB. The STM32L151xC and STM32L152xC devices offer up to 23 capacitive sensing channels to simply add a touch sensing functionality to any application.
They also include a real-time clock and a set of backup registers that remain powered in Standby mode.
Finally, the integrated LCD controller except STM32L151xC devices has a built-in LCD voltage generator that allows to drive up to 8 multiplexed LCDs with the contrast independent of the supply voltage.
The ultra-low-power STM32L151xC and STM32L152xC 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 +85 °C and -40 to +105 °C temperature ranges. A comprehensive set of power-saving modes allows the design of low-power applications.
