The STM32L452VEI6 is built around an ARM Cortex-M4 core clocked at 80 MHz. The 100-UFBGA package measures 7x7 mm. ## Connectivity and peripherals — what is on-chip This MCU integrates a rich peripheral set: CANbus, multiple I²C and SPI, UART/USART with IrDA and LIN support, a Quad-SPI interface for external Flash, SAI for audio, and USB. The USB peripheral includes an on-chip PHY — no external transceiver needed for full-speed operation. There are 83 GPIOs, a 16-channel 12-bit ADC, and a single 12-bit DAC. ## Supply range and power management The STM32L4 family is ST's ultra-low-power platform, and this part supports multiple low-power modes (Stop, Standby, Shutdown) with typical current draws in the microamp range — though the exact figures depend on the clock configuration and peripheral gating. For a battery-powered design, the wide Vcc range and low-power architecture are the key selection drivers.","metaTitle":"STM32L452VEI6 ARM Cortex-M4 MCU, 80 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32L452VEI6 32-bit MCU with ARM Cortex-M4 core at 80 MHz, 512 KB Flash, 160 KB SRAM, industrial temp range -40 to 85°C, 100-UFBGA package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tray","RAM Size":"160K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"83","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-UFBGA","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L452","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.9200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cad9ed35fe76f9279f9f7119d5fb8f94.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32L452VEI6 have a built-in USB interface or require external PHY?","answer":"The STM32L452VEI6 includes an integrated USB full-speed (12 Mbps) peripheral with an on-chip PHY.
