This is the part for designs that need more throughput and memory than the STM32L1 series (32 MHz, Cortex-M3) but don't require the 120 MHz / 1 MB tier of the STM32L4+. On the connectivity side you get CANbus for industrial fieldbus, USB (device/host/OTG) for data logging or firmware updates over a thumb drive, QSPI for memory-mapped external Flash or PSRAM, and SAI for I²S audio codecs. The 16-channel 12-bit ADC and single 12-bit DAC cover analog sensing and setpoint outputs. Brown-out detect and DMA offload the core from housekeeping tasks. STMicroelectronics lists the STM32L452RCT6 as Active. For dual-sourcing resilience, the STM32L151CBU6A (Cortex-M3, 32 MHz, 64-LQFP) is a functional cross-shop candidate if your firmware can tolerate the lower clock and memory — but it is not a pin-for-pin drop-in; review the peripheral set and supply voltage differences before committing the BOM.","metaTitle":"STM32L452RCT6 ARM Cortex-M4 MCU, 80 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32L452RCT6 32-bit MCU with 80 MHz ARM Cortex-M4, 256 KB Flash, 160 KB SRAM, 52 I/O, CAN/USB/QSPI, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32L4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"52","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-LQFP","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":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9400","priceTiers":[{"qty":1,"price":"$6.94000","currency":"USD"},{"qty":10,"price":"$6.26700","currency":"USD"},{"qty":25,"price":"$5.97520","currency":"USD"},{"qty":80,"price":"$5.18825","currency":"USD"},{"qty":230,"price":"$4.95509","currency":"USD"},{"qty":440,"price":"$4.51789","currency":"USD"},{"qty":960,"price":"$3.93493","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cad9ed35fe76f9279f9f7119d5fb8f94.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L452RCT6/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L452RCT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L452RCT6 when reusing this data.
