USB connectivity (with on-chip PHY) is available for direct PC connection, and the 13-channel 12-bit ADC plus two 12-bit DACs cover analog front-end needs without an external converter. ## Peripherals and I/O for a sensor-node design Forty GPIOs in the 48-LQFP package give enough headroom for a typical sensor hub: I²C and SPI for sensors, UART/USART for a radio module or debug console, and USB for direct host connection.","metaTitle":"STM32L072CZT7TR STM32L0 ARM Cortex-M0+ MCU, 32 MHz","metaDescription":"STMicroelectronics STM32L072CZT7TR: 32-bit ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash, 20 KB RAM, 6 KB EEPROM, 48-LQFP, -40°C to 105°C, 1.65 V to 3.6 V.","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":"Tape & Reel (TR)","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":"40","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 13x12b; 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~105°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9575","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/264c0ee7c094c660bde8f39095821f8b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32L072CZT7 and STM32L072CZT7TR?","answer":"The difference is the shipping medium: STM32L072CZT7 is typically supplied in tray or tube packaging, while the STM32L072CZT7TR suffix indicates Tape & Reel (TR) packaging intended for automated pick-and-place assembly. The silicon, firmware, and electrical ratings are identical."},{"question":"What are the alternatives to STM32L072CZT7TR?","answer":"Within the STM32L0 family, pin-compatible alternatives include the STM32L071xx series (reduced Flash/RAM, no EEPROM) and the STM32L073xx series (additional USB and LCD controller). All share the same 48-LQFP footprint and Cortex-M0+ core, so a BOM swap does not require a PCB respin. For a direct parametric match with the same 192 KB Flash and 6 KB EEPROM, the STM32L072xx base part number covers the same die in different package/shipping variants."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L072CZT7TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L072CZT7TR when reusing this data.
