The 8 KB SRAM is tight for heavy buffering — a USB CDC-ACM virtual COM port with a 1 KB transmit buffer and a 1 KB receive buffer leaves 6 KB for the stack and heap, which is workable for sensor fusion or simple control loops. If your application needs larger RAM, step up to the STM32L073 series with 20 KB SRAM. ## Connectivity and analog — USB plus 16-channel ADC for sensor fusion The 16-channel 12-bit ADC samples at up to 1 Msps, enough for reading multiple analog sensors (temperature, pressure, gas) in a round-robin loop. The single 12-bit DAC can output a control voltage for an external actuator or a reference for a comparator. The 51 GPIOs in the 64-LQFP package leave plenty of pins for a parallel LCD interface or a keypad matrix. ## Package and footprint — 64-LQFP, 10x10 mm, 0.5 mm pitch No need to derate the core speed or Flash access at the temperature extremes — the part is characterized across the full range. For under-hood or engine-bay environments, look at the AEC-Q100 qualified STM32L0 variants.","metaTitle":"STM32L053R8T6 MCU, ARM Cortex-M0+, 32 MHz, 64KB Flash","metaDescription":"STMicroelectronics STM32L053R8T6 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 64KB Flash, 8KB RAM, 2KB EEPROM, USB, 16-ch 12-bit ADC, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32L0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"64KB (64K 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":"$5.3400","priceTiers":[{"qty":1,"price":"$5.34000","currency":"USD"},{"qty":10,"price":"$4.79300","currency":"USD"},{"qty":25,"price":"$4.53160","currency":"USD"},{"qty":160,"price":"$3.92738","currency":"USD"},{"qty":320,"price":"$3.72597","currency":"USD"},{"qty":480,"price":"$3.34331","currency":"USD"},{"qty":960,"price":"$2.81966","currency":"USD"},{"qty":2400,"price":"$2.67868","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/53e74e23276668cce10b5d6ab1fe2ff9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L053R8T6/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L053R8T6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L053R8T6 when reusing this data.
