According to latest news, on -STM32L0 STMicroelectronics microcontroller family new conference , STMicroelectronics Greater China market and application microcontroller Director , Asia Pacific James Wiart said wearable devices or broader things, smart devices, such as Smart Device, Smart Phone, Smart Watch, due to equipment size, battery and other restrictions , which require higher performance, such as lower power consumption, lower cost , a cost , optimum power and performance tradeoffs. And that the ST and other chip manufacturers, a product line has been unable to meet market demand, but there is a diverse product line or differentiated product line to meet the different applications.F0 wishful method for cost- sensitive applications. A few days ago , and in the past with the release of STM32L0 L1 Cortex-M3 based STM32 do low-power product line, which is to meet some really low-power , frequency need not particularly high range product line , STM32F401 this kernel is based on Cortex-M4 , which can provide a higher-performance DSP core , while the power consumption can be reduced to within the acceptable range. In addition , ST also has the best performance of the product line (STM32F429), meet intelligent watches Smart Watch, and human-machine interface applications. It is understood that the launch of STM32L0 based CortexM0 +, while STM32L0x series microcontroller product line, low power consumption , an important point in all of the voltage range, the chip can run frequencies up to 32MHz, because in the past some product line when the voltage drops below a certain frequency will be reduced , which means low voltage performance will be limited , but the new Italian law was designed to eliminate this limitation ; in run mode, 32MHz operating power consumption is 139 microamps / MHz , can be made into real applications. It is reported that STMicroelectronics will further expand STM32L0 open ecosystem , launched a circuit board installed an e Paper display as well as to explore the suite of linear capacitive touch sensor and self-test measurement system , allowing users to measure real-time power consumption. STM32L0 explore kit is expected to be listed in 2014 . STM32L0Nucleo board and explore the suite will integrate a ST-Link/V2 hardware debugger. ST Microelectronics will provide optimized to run on Nucleo kit evaluation board and explore the STM32L0 dedicated microcontroller sample code to further help designers to achieve the lowest power consumption goals. Ultra Low Power STMicroelectronics STM32 family of microcontrollers Hakim Jaafar marketing manager , said the traditional MCU sleep when the CPU into low-power mode , the peripherals off. Today's STM32Lx and L0 product line, when the CPU is closed, the serial port can also work , which means that serial port can receive data, you can send data, from this perspective , the real has the ability to exchange data and low power consumption .HakimJaafarSTM32L meet the needs of the following aspects , one must measure accuracy ; Second, with things today , the popularity of wireless communications , data needs to be uploaded at any time , which requires RTC, RTC STMicroelectronics accuracy can be built reach 0.95ppm, higher than the traditional terms of external RTC accuracy. In addition , the wireless aspect , including networking , OF, Bluetooth, wireless future applications everywhere, the most critical point , when you wireless transmission of data , security, encryption is a very important point . That which we have hardware AES128 bit encryption algorithm .
