Package is a 48-pin UFQFN with exposed pad (7x7 mm), a compact footprint for space-constrained PCBs. ## 192 KB Flash and 6 KB EEPROM — firmware and data storage without external parts The 192 KB of Flash (192K x 8) and 6 KB EEPROM store firmware and calibration data without external parts. ## USB on board — direct PC connection for data logging and field updates USB connectivity is part of the peripheral set, which means this MCU can present itself as a virtual COM port or a mass-storage device for drag-and-drop firmware updates. For a battery-powered data logger, that eliminates an external USB-to-UART bridge IC. The USB peripheral is a standard full-speed device, not OTG, so it works as a peripheral only — fine for a sensor node that talks to a host PC or a USB charger detector. That means no last-time-buy clock is running, and the part is still in regular production at ST. The base product number is STM32L072, and the full STM32L0 series shares a common peripheral set and pinout across density options, so a migration to a larger Flash variant is straightforward if the firmware grows. ## Sourcing posture for this order code If you are filling a BOM line for a production run, send the quantity and target price band; we will source across our multi-supplier network and come back with a firm offer. For prototype quantities or a single reel, same process — just note the volume.","metaTitle":"STM32L072CZU6 ARM Cortex-M0+ MCU, 32MHz, 192KB Flash","metaDescription":"STMicroelectronics STM32L072CZU6 32-bit MCU with 32MHz ARM Cortex-M0+, 192KB Flash, 20KB SRAM, 6KB EEPROM, USB, 10x12b ADC.","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, POR, PWM, WDT","Connectivity":"I²C, IrDA, 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":"STM32L072","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)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/264c0ee7c094c660bde8f39095821f8b.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L072CZU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L072CZU6 when reusing this data.
