The 100-LQFP package gives you 80 I/O pins, enough for a control panel or a sensor hub. 256 KB of Flash is enough to hold a full RTOS kernel, a TCP/IP stack, and application code for an industrial gateway or a CAN-to-Ethernet bridge. The 64 KB RAM (organized as 64K x 8) handles moderate packet buffers and data arrays without forcing external SRAM. If you are staging OTA firmware updates, the Flash erase granularity (sector size) matters – check the reference manual for the sector map, but the density is comfortable for a single-bank update scheme. ## Connectivity mix – CAN, USB OTG, and serial lines This MCU carries CANbus and USB OTG on the same die, which is uncommon in the 100-pin STM32F1 tier. ST continues to manufacture the STM32F1 series, and the part is ROHS3 compliant. For dual-sourcing resilience, the STM32L151CBU6A is a functional alternative from the STM32L1 series – same Cortex-M3 core, similar ADC/DAC count, but clocked at 32 MHz and with a lower supply voltage floor of 1.8 V. The series trades speed for ultra-low-power operation, so the swap requires firmware and timing adjustments. Housed in a 100-LQFP (14x14 mm body), the STM32F105VCT7 is a surface-mount part with 0.5 mm pitch.","metaTitle":"STM32F105VCT7 STM32F1 ARM Cortex-M3 MCU, 72 MHz","metaDescription":"STM32F105VCT7 32-bit MCU with ARM Cortex-M3 core, 72 MHz speed, 256 KB Flash, 64 KB RAM, CAN/USB OTG, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"STM32F1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F1","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, POR, PWM, Voltage Detect, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"80","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F105","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.4400","priceTiers":[{"qty":1,"price":"$10.44000","currency":"USD"},{"qty":10,"price":"$9.42700","currency":"USD"},{"qty":25,"price":"$8.98840","currency":"USD"},{"qty":90,"price":"$7.80456","currency":"USD"},{"qty":270,"price":"$7.45385","currency":"USD"},{"qty":450,"price":"$6.79616","currency":"USD"},{"qty":990,"price":"$5.91922","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/813271393bd0544f247ae965ea1bf2b0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F105VCT7/alternatives.json"},"ai":{"faq":[{"question":"What are the direct replacements or alternatives for STM32F105VCT7?","answer":"The STM32L151CBU6A is a functional alternative from the STM32L1 series – same ARM Cortex-M3 core, similar 12-bit ADC/DAC count, but clocked at 32 MHz instead of 72 MHz and with a 1.8 V minimum supply.
