The 6 KB SRAM is enough for a few packet buffers and modest state machines, but not for frame buffers or large data arrays. ## Connectivity and peripherals — USB, CAN, and serial interfaces on a 32-pin package The 26 I/O pins in the 32-LQFP package leave enough headroom for a handful of sensors, an LED bank, or a small keypad alongside the communication lines. ## Active lifecycle — no LTB concern for production planning This means it remains suitable for new design-ins and production ramps without supply-risk from discontinuation. ## Package and footprint — 32-LQFP hand-solderable The 32-LQFP package with a 7x7 mm body and 0.8 mm pitch is a standard quad flat pack that reflows easily and can be hand-soldered for prototyping or rework. No BGA reball or X-ray inspection is needed.","metaTitle":"STM32F042K4T6 ARM Cortex-M0 MCU, 48 MHz, 16 KB Flash","metaDescription":"STMicroelectronics STM32F042K4T6 32-bit MCU, ARM Cortex-M0 at 48 MHz, 16 KB Flash, 6 KB SRAM, USB/CAN, -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":"16KB (16K 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":"$3.6700","priceTiers":[{"qty":1,"price":"$3.67000","currency":"USD"},{"qty":10,"price":"$3.29700","currency":"USD"},{"qty":25,"price":"$3.11640","currency":"USD"},{"qty":80,"price":"$2.70100","currency":"USD"},{"qty":250,"price":"$2.56248","currency":"USD"},{"qty":500,"price":"$2.29928","currency":"USD"},{"qty":1000,"price":"$1.93916","currency":"USD"},{"qty":2500,"price":"$1.84220","currency":"USD"},{"qty":5000,"price":"$1.77295","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2c1922c6f0807cc91ffca510b8e89a8e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F042K4T6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F042K4T6 and STM32F042K6T6?","answer":"The STM32F042K6T6 doubles the Flash memory to 32 KB and the SRAM to 6 KB (same SRAM as the K4).
