概述

STM32L4P5xx是一种基于高性能Arm的超低功耗微控制器器件(STM32L4+系列的一部分)

皮质

-M4 32位RISC内核。

Cortex-M4核心采用单精度浮点单元(FPU)，支持所有Arm处理器

单精度数据处理指令和所有数据类型。

这些设备嵌入高速存储器(高达1mbyte的闪存和320kbytes的SRAM)，一个灵活的外部存储器控制器(FSMC)用于静态存储器(用于具有100个引脚以上封装的设备)，两个OCTOSPI闪存接口(用于具有100个引脚或更多封装的设备)和广泛的增强I/ o和连接到两个APB总线，两个AHB总线和32位多AHB总线矩阵的外设。

这些设备为嵌入式闪存和SRAM嵌入了几种保护机制:读出保护、写入保护、专有代码读出保护和防火墙。

这些器件提供两个快速12位adc (5 Msps)，两个比较器，两个运算放大器，两个DAC通道，一个内部电压参考缓冲器，一个低功耗RTC，两个通用32位定时器，两个专用于电机控制的16位PWM定时器，七个通用16位定时器和两个16位低功耗定时器。

它们还具有标准和高级通信接口，例如:

—4个i2c

- 3个spi

-三个UART，两个UART和一个低功率UART

-两个SAIs

—2台sdmmc

-一个可以

-一个USB OTG全速

-摄像头接口

-同步并行数据接口(PSSI)

器件工作温度范围为-40 ~ +85℃(+105℃结)和-40 ~ +125℃(+130℃结)，电源电压范围为1.71 ~ 3.6 V。

支持一些独立电源，例如用于ADC、DAC、opamp和比较器的模拟独立电源输入，用于USB的3.3 V专用电源输入和最多14个I/ o，可独立供电至1.08 V。

STM32L4P5xx系列提供从48引脚到169引脚的8种封装。
