The 83 available I/O in the 100-LQFP package give enough headroom for a parallel LCD or a memory-mapped FPGA interface alongside the usual UART, SPI, and I2C peripherals. ## Supply range and battery-edge operation The 1.71 V floor is the key number for a two-cell alkaline or single Li-ion design — the MCU stays alive through the battery's full discharge curve without a boost converter. At the high end, 3.6 V aligns with standard 3.3 V rails and Li-ion full-charge voltage. ## Peripheral set for system-level integration Connectivity includes CANbus, USB, QSPI, SAI, and multiple UART/USART, SPI, and I2C interfaces. The QSPI interface lets you memory-map an external serial NOR Flash for code shadowing or data logging without chewing up GPIO for a parallel bus. The SAI peripheral supports I2S audio codecs. On-chip data converters provide 16-channel 12-bit ADC and a single 12-bit DAC. Brown-out detect, reset, DMA, and a watchdog timer are integrated, reducing external BOM for supervisory circuits. ## Lifecycle and sourcing posture For new designs, the active lifecycle removes the supply-risk flag that obsolete or NRND parts carry.","metaTitle":"STM32L452VET6 ARM Cortex-M4 MCU, 80MHz, 512KB Flash","metaDescription":"STMicroelectronics STM32L452VET6 32-bit ARM Cortex-M4 MCU at 80MHz with 512KB Flash and 160KB SRAM in 100-LQFP.
