The 128 KB Flash and 20 KB RAM define the firmware budget: enough for a modest RTOS, a USB stack, and a sensor-fusion library, but you will be counting bytes on a complex BLE or graphics application. The 6 KB embedded EEPROM is the standout — it saves an external serial EEPROM for parameter storage, which on a battery-powered board can cut both BOM cost and PCB area. Boots from internal Flash with the BOOT0 pin strapped low; the SWD debug port stays alive even with the independent watchdog enabled. The 32 MHz PLL requires the Flash wait state set to 1 before raising the core clock above 16 MHz, or the first branch instruction hard-faults. The 64-LQFP package with 51 I/O gives enough pins for a parallel LCD interface plus sensor and actuator signals without multiplexing.","metaTitle":"ST STM32L083RBT6 ARM Cortex-M0+ MCU, 32 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32L083RBT6 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 128 KB Flash, 20 KB RAM, 6 KB EEPROM, 64-LQFP, -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":"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":"STM32L083","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)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9194","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94e01ab99bb60a1f72bc513d7b3677a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32L083RBT6?","answer":"The STM32L073RBT6 is pin-compatible in the same 64-LQFP package.
