On-chip data converters are A/D 16x12-bit and D/A 1x12-bit, adequate for analog sensor readout and control-loop feedback.","metaTitle":"STM32L451VEI6 STM32L4 MCU, ARM Cortex-M4 80MHz, 512KB Flash","metaDescription":"STMicroelectronics STM32L451VEI6 32-bit ARM Cortex-M4 MCU at 80 MHz with 512 KB Flash and 160 KB SRAM in a 100-UFBGA package.
