The data converter block integrates a 16-channel 12-bit ADC and a single 12-bit DAC, enough for sensor acquisition and analog output in a mixed-signal control loop. ## Supply range and oscillator An internal oscillator is on-die, reducing external BOM count for clock generation.","metaTitle":"STM32L052R8T7 ARM Cortex-M0+ MCU, 32 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32L052R8T7 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 64 KB Flash, 8 KB RAM, 2 KB EEPROM, 51 I/O, -40 to 105°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, 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":"STM32L052","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4809","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0e08a9b8947f5c1faa7dae988a3ee99f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32L052R8T7 pin compatible with STM32L052R8T6?","answer":"Yes, the STM32L052R8T7 and STM32L052R8T6 share the same base product number STM32L052 and the same 64-LQFP package. The difference is the temperature grade: the T7 suffix indicates the -40 to 105°C range, while the T6 suffix covers -40 to 85°C.
