The part belongs to the STM32L0 series, ST's entry-level energy-efficient family aimed at battery-powered, portable, and industrial sensor nodes where every microamp matters. ## Package and footprint — the 32-UFQFPN with exposed pad Housed in a 32-UFQFN Exposed Pad package (supplier device package 32-UFQFPN, 5x5 mm), this is a compact, surface-mount device with a thermal pad underneath. The 27 general-purpose I/O pins are enough for a sensor hub or a small control panel with a few buttons, LEDs, and a serial interface. ## On-chip analog and connectivity The internal oscillator keeps the clock tree simple for many applications.","metaTitle":"ST STM32L052K8U6D ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L052K8U6D 32-bit ARM Cortex-M0+ MCU at 32 MHz with 64 KB Flash, 8 KB SRAM, 2 KB EEPROM, 27 I/O, 10x12b ADC, 1x12b DAC, -40 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":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"2K 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":"27","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L052","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1553","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0e08a9b8947f5c1faa7dae988a3ee99f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32L052K8U6 and STM32L052K8U6D?","answer":"The 'D' suffix typically denotes a specific shipping or packing variant — often tray versus tape-and-reel, or a minor revision.
