With 52 general-purpose I/O and a 16-channel 12-bit ADC plus a single 12-bit DAC, it covers mixed-signal sensing and actuation in a single chip. For a production BOM this means no LTB risk and a stable supply channel through authorized distribution.","metaTitle":"STM32L452RET6 STM32L4 MCU, 80 MHz Cortex-M4, 512KB Flash","metaDescription":"STMicroelectronics STM32L452RET6 32-bit ARM Cortex-M4 MCU, 80 MHz, 512KB Flash, 160KB SRAM, 1.71-3.6V, -40 to 85°C, 64-LQFP.","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":"512KB (512K 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":"$8.3500","priceTiers":[{"qty":1,"price":"$8.35000","currency":"USD"},{"qty":10,"price":"$7.54000","currency":"USD"},{"qty":25,"price":"$7.18920","currency":"USD"},{"qty":160,"price":"$6.24231","currency":"USD"},{"qty":320,"price":"$5.96178","currency":"USD"},{"qty":480,"price":"$5.43573","currency":"USD"},{"qty":960,"price":"$4.73434","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cad9ed35fe76f9279f9f7119d5fb8f94.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L452RET6/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives to STM32L452RET6?","answer":"Within the STM32L4 family, the STM32L452RCT6 is a pin-compatible drop-in with 256 KB Flash instead of 512 KB — the same 80 MHz Cortex-M4 core, 160 KB SRAM, and peripheral set. The older STM32L151CBU6A (Cortex-M3, 32 MHz, 128 KB Flash) is not a direct performance or memory substitute; the STM32L452RET6 offers roughly 2.5× the core speed and 4× the Flash for applications needing more compute or firmware space."},{"question":"What development boards support STM32L452RET6?","answer":"STMicroelectronics offers the NUCLEO-L452RE and STM32L452E-DISCO discovery kit, both built around the STM32L452RET6.
