概述
STM32L552xx器件是基于高性能Arm的超低功耗微控制器系列(STM32L5系列)
®
皮质
®
-M33 32位RISC内核。
大脑皮层
®
-M33内核的特点是单精度浮点单元(FPU),它支持所有Arm
®
单精度数据处理指令和所有数据类型。
®
-M33内核还实现了一整套DSP(数字信号处理)指令和内存保护单元(MPU),增强了应用程序的安全性。
这些器件嵌入高速存储器(512 kb闪存和256 kb SRAM),用于静态存储器的灵活外部存储器控制器(FSMC)(用于具有100引脚及以上封装的器件),Octo-SPI闪存接口(适用于所有封装)和广泛的增强型I/ o和外设连接到两个APB总线,两个AHB总线和32位多AHB总线矩阵。
STM32L5系列器件提供符合Arm可信安全架构(TBSA)要求的安全基础。
STM32L552xx器件为嵌入式闪存和SRAM嵌入了几种保护机制:读出保护、写保护、安全和隐藏保护区域。
STM32L552xx器件嵌入外围设备,增强安全性;
—一个HASH硬件加速器
-一个真正的随机数生成器
STM32L5系列设备提供主动篡改检测和保护,防止瞬态和环境扰动攻击,这要归功于几个内部监控,这些监控会在攻击发生时生成秘密数据擦除。
STM32L5系列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
- 1个SDMMC
-一个FDCAN
- USB设备FS
—USB Type-C / USB供电控制器
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,如ADC、DAC、opamp和比较器的模拟独立电源输入,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。
STM32L552xx器件提供从48引脚到144引脚的七种封装。
