ST STM32 Nucleo板32位MCU开发方案
ST公司的STM32 Nucleo开发板包括NUCLEO-F030R8(支持STM32F0), NUCLEO-F103RB(支持STM32F), NUCLEO-F401RE(支持STM32F4)和NUCLEO-L152RE(支持STM32L1),适合各种性能,功耗和特性的组合. STM32 Nucleo开发板集成了ST-Link调试器/编程器,能和各种开发环境如IAR EWARM, Keil MDK, mbed, 基于GCC的IDEs (Atollic TrueStudio)一起使用,很容易开发出STM32 MCU的新原型.本文介绍了STM32L1 32位MCU主要特性和框图,以及STM32 Nucleo开发板主要特性,框图,电路图,材料清单和PCB元件布局图.
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.
