STM32L451RCT6

STM32L451RCT6 is an ultra-low-power Arm® Cortex®-M4 32bit MCU+FPU, 100DMIPS, 160KB SRAM, analogue, audio. The Cortex-M4 core features a Floating point unit (FPU) single precision that supports all Arm® single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security, This device embed high-speed memories, a Quad SPI Flash memories interface and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32bit multi-AHB bus matrix. This device embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall. This feature standard and advanced communication interfaces, namely four I²Cs, three SPIs, three USARTs, one UART and one Low-Power UART, one SAI, one SDMMC, one CAN.
