A typical bootloader plus a modest application — say, a Modbus RTU slave with a few analog inputs — fits in about 8–10 KB of code, leaving headroom for a small OTA staging area if you use the 1 KB page erase granularity. The 4 KB SRAM limits buffering: a single 1 KB UART FIFO plus a 512-byte protocol stack leaves about 2.5 KB for stack and variables. ## Obsolete — what it means for procurement No further factory orders are accepted, and no last-time-buy window remains open. A design-in for new projects is not viable; a pin-compatible migration to a current STM32F0 variant is the recommended long-term fix.","metaTitle":"STM32F050C4T6A ARM Cortex-M0 MCU, 48 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F050C4T6A 32-bit ARM Cortex-M0 MCU, 48 MHz, 16 KB Flash, 4 KB RAM, 48-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tray","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"39","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-LQFP","Product Status":"Obsolete","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F050","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$48.8900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8be81441a825aba1018fa841300e9c69.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F050C4T6A/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F050C4T6A obsolete?","answer":"Yes, STMicroelectronics lists the STM32F050C4T6A as obsolete.
