That combination is unusual at the 32 KB Flash level and makes the STM32F042K6T6 a natural fit for set-top boxes, smart remote controls, display interface boards, and IoT gateway nodes that need to bridge USB to CAN or I²C. The 26 GPIOs in the 32-LQFP package leave enough headroom for a small keypad, a few LEDs, and an external serial flash if the 32 KB program space gets tight. ## Industrial temperature, active lifecycle, RoHS3 It carries ROHS3 compliance, so it passes the EU material restriction directive without an exemption. ## 32-LQFP footprint — manual assembly and rework friendly The 32-LQFP package with a 7x7 mm body and 0.8 mm pitch is a standard low-profile quad flat pack. No hidden balls, no via-in-pad requirement — just a straightforward footprint that matches the 32-LQFP land pattern in any PCB layout tool. ## What this MCU is not — and why that matters for sourcing This is a Cortex-M0, not an M3 or M4. The 48 MHz ceiling and 6 KB SRAM mean it will not run a real-time OS with a TCP/IP stack and a GUI — the memory just is not there. If your design needs more than a few kilobytes of heap or a second UART, the STM32F042K6T6 is the wrong starting point. But for a dedicated control task — a USB-to-CAN dongle, a single-zone thermostat, a battery monitor that samples one voltage and sends it over I²C — the 48 MHz core is overkill, not under. The comparison with the STM32L151CBU6A (Cortex-M3, 32 MHz, larger SRAM, more I/O) is a class jump: the series targets ultra-low-power battery applications with a richer peripheral set, but at a higher unit cost. The STM32F042K6T6 stays in the value tier where the BOM dollar buys the connectivity, not the core. ## Sourcing this line — what the procurement desk needs The shipping medium is Tray, which is the standard for 32-LQFP devices; no reel or tape fees apply unless a reeled variant is requested separately.","metaTitle":"STM32F042K6T6 STM32F0 ARM Cortex-M0 MCU, 48 MHz, 32KB Flash","metaDescription":"STM32F042K6T6 32-bit ARM Cortex-M0 MCU from STMicroelectronics, 48 MHz core, 32KB Flash, 6KB SRAM, USB + CAN, 13x12b ADC, -40 to 85°C, 32-LQFP.","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 ~ 85°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8400","priceTiers":[{"qty":1,"price":"$3.84000","currency":"USD"},{"qty":10,"price":"$3.45200","currency":"USD"},{"qty":25,"price":"$3.26360","currency":"USD"},{"qty":80,"price":"$2.82850","currency":"USD"},{"qty":250,"price":"$2.68340","currency":"USD"},{"qty":500,"price":"$2.40780","currency":"USD"},{"qty":1000,"price":"$2.03067","currency":"USD"},{"qty":2500,"price":"$1.92914","currency":"USD"},{"qty":5000,"price":"$1.85662","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2c1922c6f0807cc91ffca510b8e89a8e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F042K6T6/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F042K6T6 compatible with STM32F042K4T6?","answer":"Yes, the two parts share the same base product number STM32F042 and the same 32-LQFP package, pinout, and peripheral set.
