The 20 K x 8 SRAM handles a few KB of stack plus a couple of large buffers — enough for a sensor fusion algorithm or a small display framebuffer. If your firmware pushes past 100 KB, look at the 192 KB or 256 KB Flash variants in the same L0 family; they share the same 64-LQFP footprint. ## Package and rework — 64-LQFP The 64-LQFP (10x10 mm body) is a standard fine-pitch gull-wing package. It reflows cleanly with a standard lead-free profile; the exposed pad is absent, so you don't need a bottom-side heater. The tray shipping medium is fine for low-volume builds; for reeled tape, order the 'TR' suffix variant. ## Lifecycle and supply posture ST lists the STM32L072RBT6 as Active. For dual-source resilience, the STM32L072xx family includes pin-compatible density variants that share the same 64-LQFP footprint — a straightforward BOM alternate if firmware fits.","metaTitle":"STM32L072RBT6 ARM Cortex-M0+ MCU, 32MHz, 128KB Flash","metaDescription":"STMicroelectronics STM32L072RBT6 32-bit MCU with ARM Cortex-M0+ core at 32MHz, 128KB Flash, 20K x 8 RAM, 6K x 8 EEPROM, 64-LQFP.","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":"51","Core Processor":"ARM® Cortex®-M0+","Package / Case":"64-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":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.0900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/67cb9094f3e6522ca004c703798dd6eb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32L072RBT6 in this component family?","answer":"Within the STM32L072xx series, the 64-LQFP footprint is shared across density variants.
