On-chip analog includes a 16-channel 12-bit ADC and two 12-bit DAC channels, which reduces the external signal-chain BOM for mixed-signal designs like portable instrumentation or environmental monitors. ## Supply and power budget At 3.0 V the part can sustain a 32 MHz CPU clock; dropping below about 2.0 V the maximum clock rate reduces, but the MCU remains operational down to 1.65 V. This means a design running from two AA cells or a Li-SOCl2 battery can stay alive through the entire discharge curve without a boost converter. Brown-out detect and POR are integrated peripherals, so no external supervisor is needed for clean power-on reset or brown-out recovery. The watchdog timer (WDT) can be enabled in hardware to catch firmware hangs in unattended equipment. ## Memory architecture and firmware strategy The 64 KB Flash is sized for mid-complexity firmware — sensor fusion algorithms, USB protocol stacks, or Modbus RTU slaves fit comfortably. The 20 KB SRAM supports moderate data buffering, and the separate 3 KB EEPROM (emulated or true EEPROM cells depending on the STM32L0 variant) allows wear-leveled storage of calibration data, serial numbers, or logging counters without consuming Flash erase cycles. DMA offloads peripheral-to-memory transfers for ADC conversions, SPI data streaming, or UART reception, keeping the Cortex-M0+ free for control loops rather than byte-shuffling. ## Connectivity and debug IrDA support covers optical isolation links in industrial environments. The 100-LQFP package with 0.5 mm pitch routes reasonably on a two-layer board, though the 84 I/O count means careful signal assignment to avoid congested routing channels. The 14x14 mm body fits compact enclosures. ## Lifecycle and sourcing The base product number STM32L072 covers a range of Flash and RAM density options in the same 100-pin footprint, providing a pin-compatible upgrade path within the family without a PCB spin.","metaTitle":"STM32L072V8T6 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L072V8T6 32-bit ARM Cortex-M0+ MCU at 32 MHz with 64 KB Flash, 20 KB RAM, 3 KB EEPROM, 16x12b ADC, 2x12b DAC, 84 I/O, 100-LQFP, -40°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":"3K 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":"84","Core Processor":"ARM® Cortex®-M0+","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L072","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3409","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/67cb9094f3e6522ca004c703798dd6eb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STM32L072V8T6 have a pin-compatible alternative in the same family?","answer":"The base product number STM32L072 covers multiple Flash and RAM density options in the same 100-pin LQFP footprint.
