 尝试了解新产品： ST公司的STM32 Nucleo
The ultralow power STM32L15xxx incorporates the connectivity power of the universal serial bus (USB) with the high-performance ARM Cortex-M3 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 128 Kbytes and RAM up to 16 Kbytes) and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer a 12-bit ADC, 2 DACs and 2 ultralow power comparators, six general-purpose 16-bit timers and two basic timers, which can be used as time bases. Moreover, the STM32L15xxx devices contain standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs and a USB. 

The STM32L15xxx devices offer up to 20 capacitive sensing channels to simply add 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 has a built-in LCD voltage generator that allows you to drive up to 8 multiplexed LCDs with contrast independent of the supply voltage. The ultralow power STM32L15xxx operates 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. It is available in the -40 to +85 ℃ temperature range, extended to 105℃ in low power dissipation state. A comprehensive set of power-saving modes allows the design of low-power applications.

These features make the ultralow power STM32L15xxx microcontroller family suitable for a wide range of applications:

• Medical and handheld equipment 
• Application control and user interface 
• PC peripherals, gaming, GPS and sport equipment 
• Alarm systems, Wired and wireless sensors, Video intercom 
• Utility metering
