At the low end, 1.65 V operation lets the MCU stay alive during battery discharge without a boost converter — useful for portable and battery-backed designs. ## USB device capability — confirmed on the connectivity list The USB peripheral supports control, bulk, and interrupt transfers — enough for virtual COM port, HID, or custom device class implementations. The 32 KB Flash and 6 KB RAM are tight for composite USB devices, but a single-interface USB CDC or HID firmware fits comfortably. Housed in a 32-LQFP (7x7 mm body, 0.8 mm pitch), this is a hand-solderable, inspectable package — no BGA rework needed. The exposed pad is not present on this package variant, so all heat dissipation goes through the leads. For a 48 MHz Cortex-M0 drawing maybe 20-30 mA typical, that's fine; just ensure adequate copper on the power pins. The tray shipping medium means the parts arrive in antistatic trays, not tape-and-reel — factor that into your pick-and-place feeder setup if you're running high volume.","metaTitle":"STM32F042K6T7 ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F042K6T7 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 32 KB Flash, 6 KB RAM, USB, CAN, industrial -40°C to 105°C range.","metaKeywords":null},"attributes":{"series":"STM32F0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tray","RAM Size":"6K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, HDMI-CEC, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"26","Core Processor":"ARM® Cortex®-M0","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 13x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F042","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0800","priceTiers":[{"qty":1,"price":"$4.08000","currency":"USD"},{"qty":10,"price":"$3.66900","currency":"USD"},{"qty":25,"price":"$3.46840","currency":"USD"},{"qty":80,"price":"$3.00588","currency":"USD"},{"qty":250,"price":"$2.85172","currency":"USD"},{"qty":500,"price":"$2.55882","currency":"USD"},{"qty":1000,"price":"$2.15805","currency":"USD"},{"qty":2500,"price":"$2.05014","currency":"USD"},{"qty":5000,"price":"$1.97307","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2c1922c6f0807cc91ffca510b8e89a8e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F042K6T7/alternatives.json"},"ai":{"faq":[{"question":"Can I use STM32F042K6T7 for a USB device?","answer":"Yes, this MCU includes a USB 2.0 device controller as part of its connectivity peripherals.
