The 128 KB program memory is sized for a modest application stack — a USB CDC class driver, a few sensor drivers, and a simple control loop fit comfortably. The 16 KB SRAM is the tighter resource: a USB buffer consumes about 1 KB per endpoint pair, and a modest RTOS kernel takes another 2–4 KB, leaving 10–12 KB for application data. If your design needs a GUI framebuffer or large DMA buffers, the RAM budget will be the first constraint you hit. ## USB 2.0 full-speed device — the differentiator The USB peripheral is the headline feature on this F0 variant. It supports control, bulk, interrupt, and isochronous transfers, with a dedicated 48 MHz clock from the internal oscillator — no external crystal required for USB operation. This makes the STM32F070CBT6TR a natural fit for USB-CDC virtual COM ports, HID-class devices (keyboards, mice, gamepads), and DFU-based firmware updates. The STM32Cube firmware package includes ready-to-port USB device class examples. The wide supply range lets you run directly from a 3.3 V rail, a 2.5 V logic supply, or a single Li-ion cell down to 2.4 V. The internal POR and brown-out reset handle startup sequencing, so the BOM stays lean — no external supervisor needed for most designs. At 48 MHz the typical active current is in the 20–30 mA range; stop-mode current drops below 5 µA with the RTC running. It is ROHS3 compliant.","metaTitle":"STM32F070CBT6TR ARM Cortex-M0 MCU, 48 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F070CBT6TR 32-bit MCU with ARM Cortex-M0 core at 48 MHz, 128 KB Flash, 16 KB RAM, USB 2.0, 37 I/O, 48-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":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 13x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F070","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2.4V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2600","priceTiers":[{"qty":1,"price":"$3.26000","currency":"USD"},{"qty":10,"price":"$2.93000","currency":"USD"},{"qty":25,"price":"$2.77000","currency":"USD"},{"qty":100,"price":"$2.40060","currency":"USD"},{"qty":250,"price":"$2.27752","currency":"USD"},{"qty":500,"price":"$2.04360","currency":"USD"},{"qty":1000,"price":"$1.72352","currency":"USD"},{"qty":2400,"price":"$1.63735","currency":"USD"},{"qty":4800,"price":"$1.57579","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5714438e9641ce9807794f7e58a35616.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F070CBT6TR/alternatives.json"},"ai":{"faq":[{"question":"Can the STM32F070CBT6TR be used for USB communication?","answer":"Yes, it has a USB 2.0 full-speed device peripheral supporting control, bulk, interrupt, and isochronous transfers.
