No external boost converter is needed when powering from a single alkaline cell down to 1.65 V, which simplifies the BOM and saves board space. The brown-out detect and POR peripherals keep the core safe during ramp-up and sag. ## 32 KB Flash, 8 KB SRAM, 2 KB EEPROM — sizing the firmware budget The 32 KB Flash and 8 KB SRAM place this MCU in the entry-level density tier of the STM32L053 family. The 2 KB of true EEPROM (not emulated) survives 100k write cycles and is useful for calibration constants or configuration data that must persist across resets without wearing the Flash. If your application needs more than 32 KB of code space, the STM32L053C8 or STM32L053R8 siblings double the Flash to 64 KB while staying pin-compatible. ## Peripheral set: LCD, USB, 16-channel ADC, and more This MCU integrates a segment LCD driver capable of driving up to 8x40 or 4x44 segments, which is rare in a 32-bit MCU at this price point. The USB 2.0 full-speed interface (with internal oscillator) handles device-side communication without an external crystal. The 16-channel 12-bit ADC and single 12-bit DAC cover analog front-end needs for sensor conditioning and control loops. The base product number STM32L053 covers the full family, and the R6T6 variant is widely stocked across distribution channels.","metaTitle":"STM32L053R6T6 ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STM32L053R6T6 32-bit MCU from STMicroelectronics: ARM Cortex-M0+ core at 32 MHz, 32 KB Flash, 8 KB SRAM, 2 KB EEPROM, 1.65-3.6 V supply, -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, I²S, LCD, 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 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L053","Program Memory Size":"32KB (32K 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":"$6.1600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/53e74e23276668cce10b5d6ab1fe2ff9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32L053R6T6 and STM32L052R8?","answer":"The STM32L053R6T6 has 32 KB Flash and 8 KB SRAM, while the STM32L052R8 doubles the Flash to 64 KB and the SRAM to 8 KB (same SRAM).
