Connectivity includes I²C, IrDA, LINbus, SPI, UART/USART, and USB, with 37 I/Os. ## Industrial temperature range and small-footprint package The 48-UFQFN exposed-pad package (7x7 mm) keeps board area tight. The thermal pad helps pull heat into the PCB ground plane. The base product number is STM32L073. PCN or errata updates are published under that family umbrella.","metaTitle":"STM32L073CZU6D ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STMicroelectronics STM32L073CZU6D 32-bit MCU, ARM Cortex-M0+ core at 32 MHz, 192 KB Flash, 6 KB EEPROM, 20 KB RAM, -40 to 85°C, 48-UFQFPN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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, I²S, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L073","Program Memory Size":"192KB (192K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7868","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4871e6ea19450d665776dfcf01cc08ff.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the CPU architecture of STM32L073CZU6D?","answer":"It uses a 32-bit ARM Cortex-M0+ core, single-core design, running at up to 32 MHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L073CZU6D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L073CZU6D when reusing this data.
