Typical applications include battery-powered IoT edge nodes, portable medical monitors, smart sensors, and wireless environmental loggers where every microamp matters. ## Memory and peripheral budget — sizing the BOM With 192 KB of Flash and 20 KB of RAM, this part fits firmware images for BLE stacks, sensor drivers, and a modest application layer. The 6 KB EEPROM is useful for calibration constants, device IDs, and configuration parameters that survive a firmware update. The 25 general-purpose I/Os in the 32-LQFP package are enough for a sensor array with SPI or I²C bus, a few pushbuttons, and status LEDs. ## Supply voltage and temperature — where it works No extended-temperature or automotive qualification here, so it stays in the commercial/industrial tier.","metaTitle":"STM32L072KZT6 ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STMicroelectronics STM32L072KZT6 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 192 KB Flash, 20 KB RAM, 6 KB EEPROM, 10x12b ADC, 2x12b DAC, USB, in 32-LQFP.","metaKeywords":null},"attributes":{"series":"STM32L0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"32MHz","Series":"STM32L0","Package":"Tray","RAM Size":"20K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"6K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L072","Program Memory Size":"192KB (192K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.6800","priceTiers":[{"qty":1,"price":"$5.68000","currency":"USD"},{"qty":10,"price":"$5.10600","currency":"USD"},{"qty":25,"price":"$4.82680","currency":"USD"},{"qty":80,"price":"$4.18325","currency":"USD"},{"qty":230,"price":"$3.96870","currency":"USD"},{"qty":440,"price":"$3.56109","currency":"USD"},{"qty":1500,"price":"$3.00333","currency":"USD"},{"qty":3000,"price":"$2.85317","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/67cb9094f3e6522ca004c703798dd6eb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L072KZT6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L072KZT6 and STM32L073KZT6?","answer":"The STM32L073KZT6 is a close sibling in the same STM32L0 series, typically offering additional USB crystal-less operation and a few more peripheral options. The core, memory, and package are identical; the difference is in the USB PHY integration. Check the STM32L0 reference manual for the exact peripheral set delta."},{"question":"Can STM32L072KZT6 be used in battery-powered IoT devices?","answer":"Yes, the 1.65 V minimum supply voltage, 32 MHz Cortex-M0+ core with multiple low-power modes, and integrated ADC/DAC make it well suited for battery-powered IoT edge nodes, wireless sensor tags, and portable instruments. The 192 KB Flash and 20 KB RAM are sufficient for BLE stacks and sensor fusion firmware."},{"question":"What is the closest functional second-source for STM32L072KZT6?","answer":"The STM32L151CBU6A is a functional alternative from the STM32L1 series, featuring a Cortex-M3 core at 32 MHz, 37 I/Os, and a 16-channel 12-bit ADC. It offers more processing headroom and analog channels but draws higher active current. It is not pin-compatible — the STM32L151CBU6A comes in a 48-pin package — so a board redesign is required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L072KZT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L072KZT6 when reusing this data.
