STM32L4P5RE规格参数_功能特性_原装供应
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。
