The 48-UFQFN package with exposed pad keeps the footprint small while the pad helps pull heat out in compact enclosures. ## Peripherals and connectivity for sensor fusion The part includes a 10-channel 12-bit ADC, brown-out detect, DMA, I²S, PWM, and a watchdog timer. Connectivity covers I²C, IrDA, SPI, and UART/USART — enough to talk to common MEMS sensors, displays, and radio modules without an external interface chip. ## 37 I/Os in a 48-pin package — what that means for layout With 37 I/Os brought out of a 48-UFQFN, the pin-to-pin pitch is tight — expect 0.5 mm or finer. The 1.65 V minimum supply means the I/Os are 3.3 V tolerant but not 5 V; level shifting is required for legacy 5 V peripherals.","metaTitle":"STM32L071CZU6 ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STM32L071CZU6 is a 32-bit ARM Cortex-M0+ MCU from STM32L0 series. 32 MHz core, 192 KB Flash, 20 KB SRAM, 6 KB EEPROM. 1.65 V to 3.6 V supply. -40°C to 85°C.","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, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","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","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L071","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":"$6.3300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/800dd075f25aea742da71c4c42c978e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32L071CZU6 pin compatible with STM32L072?","answer":"The STM32L071 and STM32L072 share the same pinout in the 48-UFQFN package, but the L072 adds a USB controller and larger SRAM.
