STM32L451VET6 belongs to the family of ultra-low-power MCUs provided by STMicroelectronics. It is designed based on the high-performance Arm?Cortex?-M4 32-bit RISC core which operates at up to 80 MHz frequency. A full set of DSP instructions and a memory protection unit (MPU) are integrated to improve application security. Moreover, it supports a suite of protection mechanisms for embedded Flash memory and SRAM, including readout protection, write protection, proprietary code readout protection, and Firewall.
