Typical applications include appliance control panels, sensor hubs, and consumer AV gear where HDMI-CEC is needed for remote control pass-through. The 48 MHz core speed is the entry-level sweet spot for the STM32F0 family: fast enough for a UART-to-USB bridge, a simple motor commutation loop, or a CAN gateway, but not overkill for a cost-sensitive BOM. The 128 KB Flash is the mid-density option — enough for a modest firmware stack with a bootloader and a few protocol layers, but you will hit the wall if you try to cram a full RTOS with TCP/IP and a GUI. The 16K x 8 SRAM (16 KB) is tight; watch your stack and DMA buffer allocation, especially if you are using USB with double-buffered endpoints. The 1.65 V minimum supply means this part can stay alive on a battery that has mostly drained, which is a real advantage in portable or backup-power scenarios. ## Package and I/O — 100-LQFP with 86 pins to route The 100-LQFP (14x14 mm) gives you 86 usable I/O pins — enough to drive a parallel LCD, a keypad matrix, and a few external peripherals without a port expander. No exposed pad here, so thermal dissipation is through the leads only; keep the ambient load under 85°C and you are fine. The surface-mount footprint is the same as other 100-pin LQFP STM32 parts, so a board layout for an STM32F103 or STM32F4 in the same package will fit with a BOM swap. ## Peripherals you actually use The HDMI-CEC block is the niche feature: if your design needs to send or receive CEC commands on an HDMI link, this part handles it without an external translator chip. The STM32F0 series is a mature, volume-driven line, so supply through independent distribution is steady. If you are dual-sourcing, the STM32L151CBU6A (Cortex-M3, 32 MHz, 1.8 V) is a functional alternative with a different core and lower speed — check your firmware port before substituting.","metaTitle":"STM32F078VBT6 STM32F0 ARM Cortex-M0 MCU, 48 MHz","metaDescription":"STMicroelectronics STM32F078VBT6 32-bit MCU with ARM Cortex-M0 core, 48 MHz speed, 128 KB Flash, 16K x 8 RAM, 86 I/O, HDMI-CEC, USB, 1.65 V to 3.6 V supply","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":"16K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"HDMI-CEC, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"86","Core Processor":"ARM® Cortex®-M0","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 19x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F078","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2600","priceTiers":[{"qty":1,"price":"$6.26000","currency":"USD"},{"qty":10,"price":"$5.62400","currency":"USD"},{"qty":25,"price":"$5.31720","currency":"USD"},{"qty":80,"price":"$4.60825","currency":"USD"},{"qty":230,"price":"$4.37191","currency":"USD"},{"qty":540,"price":"$3.92291","currency":"USD"},{"qty":1080,"price":"$3.30848","currency":"USD"},{"qty":2700,"price":"$3.14305","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ab6bce2548ff2fe79d8b711acab87647.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F078VBT6/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F078VBT6 support HDMI-CEC?","answer":"Yes, the connectivity block includes HDMI-CEC, so it can send and receive CEC commands on an HDMI link without an external translator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F078VBT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F078VBT6 when reusing this data.
