Product details

The STM32L452VET6 is an STMicroelectronics STM32L4 series 32-bit ARM Cortex-M4 MCU with single-precision FPU clocked at 80 MHz.

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. Brown-out detect, reset, DMA, and a watchdog timer are integrated, reducing external BOM for supervisory circuits.

For new designs, the active lifecycle removes the supply-risk flag that obsolete or NRND parts carry.
