ST STM32L151 32位MCU蓝牙低功耗(BLE)开发方案
ST公司的STM32L151VD-X和STM32L152VD-X是基于高性能ARM® Cortex®-M3 32位RISC内核的超低功耗MCU,工作频率32MHz(33.3DMIPS),集成了存储器保护单元(MPU),高速嵌入存储器(闪存高达384KB,RAM高达80KB),以及广泛的增强的I/O和连接到两条APB总线的外设.本文介绍了STM32L151VD-X和STM32L152VD-X主要特性,框图,以及蓝牙低功耗(BLE)评估板X-NUCLEO-IDB04A1主要特性,框图,电路图和材料清单.
The ultra-low-power STM32L151VD-X and STM32L152VD-X 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 384 Kbytes and RAM up to 80 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
The STM32L151VD-X and STM32L152VD-X 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.
