It carries 192 KB of Flash program memory, 20 KB of SRAM, and an integrated 6 KB EEPROM — enough for moderate firmware stacks and persistent parameter storage without an external serial EEPROM. ## Peripherals and connectivity for sensor-node and human-interface designs Connectivity covers I²C, IrDA, LINbus, SPI, UART/USART, and USB — enough for a sensor hub, a simple HMI with segment LCD, or a USB-to-serial bridge. The 40 GPIOs in the 48-UFQFN package give reasonable headroom for parallel interfaces and button/LED matrices. The device integrates a 13-channel 12-bit ADC and two 12-bit DACs, sufficient for reading analog sensors (temperature, pressure, battery voltage) and generating control voltages or audio waveforms. ## Package and thermal management — 48-UFQFN with exposed pad The exposed pad also provides a low-inductance ground return — critical for the USB interface's signal integrity. STMicroelectronics lists the STM32L082CZU6 as an active product (current lifecycle stage). The base product number STM32L082 covers a family of Flash and package options; this specific variant (CZU6) is the 48-UFQFN, -40 to 85°C grade.","metaTitle":"STM32L082CZU6 ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STMicroelectronics STM32L082CZU6 ultra-low-power 32-bit MCU, 32 MHz ARM Cortex-M0+, 192 KB Flash, 20 KB SRAM, 6 KB EEPROM, 48-UFQFN, -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":"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":"40","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L082","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":"$3.7972","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e691124bb30587d28ab89e4b3604e00c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock frequency of STM32L082CZU6?","answer":"The core runs at 32 MHz maximum.
