The 16-channel 12-bit ADC and single 12-bit DAC cover analog sensor readout and control-voltage generation without external converters. Brown-out detect and a watchdog timer are built in, which simplifies safety-critical firmware design. The internal oscillator trims to enough accuracy for UART baud-rate generation, saving a crystal on cost-sensitive boards. ## Lifecycle and sourcing posture The STM32L451 base part number is shared across the L4 family.","metaTitle":"STM32L451VET6TR ARM Cortex-M4 MCU, 80MHz, 512KB Flash","metaDescription":"STMicroelectronics STM32L451VET6TR 32-bit ARM Cortex-M4 MCU. 80MHz core, 512KB Flash, 160KB SRAM, 100-LQFP, -40°C to 85°C.
