At this clock speed, the part handles 2-3 kHz current-control loops in a brushless DC motor drive, or processes 10+ analog sensor channels through the 19-input 12-bit ADC without needing an external multiplexer. The 8 KB SRAM leaves room for a modest data buffer — enough for a 4 KB OTA staging area plus stack and heap, assuming the application does not run a full RTOS with large task stacks. ## Industrial temperature grade and 55 I/O in a 64-LQFP The 64-LQFP (10x10 mm) package breaks out 55 general-purpose I/O, which is a dense pin count for the footprint and allows routing of parallel LCD data buses or multiple UART/SPI interfaces without signal sharing. Supply voltage spans 2V to 3.6V, so the part runs directly from a 3.3V rail or a 2.5V battery supply. ## Peripherals set — DMA, PWM, and analog conversion on one die The integrated DMA engine offloads the Cortex-M0 core during ADC conversions and serial data transfers, which matters for real-time control where every cycle counts. The PWM timer channels support complementary outputs with dead-time insertion, making this part suitable for three-phase inverter control in power tools or small pumps. The 19-channel 12-bit ADC and single 12-bit DAC cover multi-sensor acquisition and analog output generation without external converters. The PVD (programmable voltage detector) and POR (power-on reset) blocks simplify the power-supervision BOM — no external reset IC needed for most designs. ## Package traceability and surface-mount handling The 64-LQFP package is MSL 3 — the moisture-sensitive floor life is 168 hours out of the sealed bag. If the reel has been exposed beyond that window, a 24-hour bake at 125°C before reflow is the standard recovery step. The laser-etched marking on the top of the package carries the date code and lot trace code; a mismatch between the date code and the reel label is the first red flag for gray-market material.","metaTitle":"STMicroelectronics STM32F051R8T7TR ARM Cortex-M0 MCU, 48MHz","metaDescription":"STM32F051R8T7TR is an active 32-bit Cortex-M0 MCU from ST with 48MHz core speed, 64KB Flash, 8KB SRAM, 55 I/O, 19x12b ADC, -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":"48MHz","Series":"STM32F0","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"55","Core Processor":"ARM® Cortex®-M0","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 19x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F051","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)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5b8222026032a8f6c67417def25d2d17.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F051R8T7TR/alternatives.json"},"ai":{"faq":[{"question":"What is the STM32F051R8T7TR's listed speed and memory?","answer":"The core runs at 48 MHz."},{"question":"Where can I find the datasheet for STM32F051R8T7TR?","answer":"The full datasheet and reference manual for the STM32F051x8 series are published by STMicroelectronics under the base product number STM32F051.
