The 512 KB Flash and 160 KB SRAM support a real-time OS, USB stack, and sensor-fusion algorithms running concurrently. ## Package and mounting The 100-UFBGA (7x7 mm) package is a fine-pitch BGA. The 0.5 mm ball pitch means the PCB needs a microvia-capable fab and an X-ray inspection step after reflow. MSL 3 out of the bag — if the moisture-barrier bag has been open past the floor-life window, bake at 125 °C for 24 hours before reflow. The 83 I/O lines are distributed across the BGA, so fanout via blind vias is the standard approach; a four-layer board with a ground plane under the BGA keeps the return paths clean. The small footprint saves board area, but hand-rework is impractical — plan for a stencil and a reflow oven. ## Industrial temperature — environment limits It is not AEC-Q100 qualified, so it does not belong in under-hood automotive modules or transmission controllers. For cabin or chassis applications that stay within the temperature range, the part can still be used if the program accepts non-automotive-grade risk — but the procurement team should flag that it lacks the PPAP documentation an automotive OEM requires. ## Peripheral set — what connects where The connectivity block includes CANbus, USB, QSPI, and up to five UART/USART channels, so this MCU can serve as a protocol bridge between a CAN sensor network and a USB-attached host. The 16-channel 12-bit ADC and single 12-bit DAC cover analog front-end capture and control-loop output. Brown-out detect and the watchdog are standard STM32 safety features — the BOR keeps the core reset until the supply crosses 1.71 V, which is useful for single-cell Li-ion designs where the voltage sags under load. For new designs, this means no immediate risk of a forced redesign.","metaTitle":"STM32L452VEI6TR ARM Cortex-M4 MCU, 80MHz, 512KB Flash","metaDescription":"STMicroelectronics STM32L452VEI6TR 32-bit MCU with ARM Cortex-M4 core at 80MHz, 512KB Flash, 160KB SRAM, industrial temp range, active lifecycle, sourced to","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":"Tape & Reel (TR)","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":"$6.2583","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9c3fbcd7d7e74f2a5d674b4a5d7e5cff.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32L452VEI6TR have pin and software compatibility with STM32L452VEI6?","answer":"The STM32L452VEI6TR shares the same base product number (STM32L452) as the STM32L452VEI6, so it is pin-compatible and software-compatible.
