ST STM32L4P5AG超低功耗ARM MCU开发方案
ST公司的STM32L4P5xx系列是超低功耗微控制器,基于高性能Arm®Cortex®-M4 32位RISC核,工作频率高达120MHz.Cortex-M4核具有单精度浮点单元(FPU),支持所有ARM单精度数据处理指令和所有数据类型.Cortex-M4核还执行全套的DSP指令和存储器保护单元(MPU),从而增强应用安全性.器件嵌入了高速存储器(高达1MB闪存和320KB SRAM),用于静态存储器的灵活外接存储器控制器(FSMC),两个OCTOSPI闪存接口和连接到两个APB总线,两个AHB总线和32为多个AHB总线矩阵的广泛的增强I/O和外接.器件具有标准和高档通信接口包括四个I2C,三个SPI,三个SPI,三个USART,两个UART和一个低功耗UART,两个SAI,两个SDMMC,一个CAN,一个USB OTG全速,照相接口和同步并行数据接口(PSSI).器件工作温度 -40到 +85℃和 -40 到+125℃,工作电压1.71V到3.6V.主要用在各种低功耗应用领域.中电网为您整理如下详细资料，本文介绍了STM32L4P5AG主要特性,框图,电源框图和时钟树,以及开发板Discovery kit STM32L4P5G-DK主要特性,电路图,材料清单和PCB设计图.
STM32L4P5xx designates a family of ultra-low-power microcontroller devices (part of STM32L4+ Series) based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 120 MHz.
The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm® single-precision data-processing instructions and all the data types. The Cortex-M4 core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application’s security.
