STM32F105VCT7 Обзор
An MCU (microcontroller unit) is a single-chip computer containing a processor core, program memory, data memory, and integrated peripherals. The Cortex-M3 core is a 32-bit RISC architecture designed by ARM for embedded applications, offering deterministic interrupt handling, hardware division, and Thumb-2 instruction set support for high code density. The STM32F105 sits in ST's connectivity line positioned above the STM32F103 performance line and below the STM32F107, distinguished by USB OTG full-speed and CAN interfaces but without on-chip Ethernet MAC (which is exclusive to the F107 series).
Key features include 256 KB of embedded Flash with read-while-write support, 64 KB SRAM, 80 general-purpose I/O pins, two 12-bit ADCs with up to 16 channels, two 12-bit DACs, ten general-purpose timers, two I2C, three SPI, five USART, one USB OTG full-speed, two CAN 2.0B interfaces, and an SDIO interface. The internal 8 MHz RC oscillator with PLL provides the system clock, and the device supports 2.0 V to 3.6 V operating voltage.
Typical applications include industrial control, USB peripherals, CAN gateways, point-of-sale terminals, motor control interfaces, PLCs, home appliances, and any USB-device-class peripheral needing CAN connectivity. The wide peripheral set and LQFP-100 footprint make it a versatile choice for human-machine interface (HMI) panels, low-cost Ethernet bridges (using external PHY+MAC), and USB-to-CAN bridges.
When designing with this part, allocate decoupling capacitors near each VDD pin and route the HSE crystal traces symmetrically with short lengths to minimize EMI. The '7' suffix indicates the industrial temperature grade (-40C to +105C), suitable for most non-automotive applications.

Типичное применение
STM32F105VCT7 подходит для 6 применениеs: USB-to-CAN Industrial Bridge, Human-Machine Interface (HMI) Panel Controller, USB Barcode Scanner / HID Peripheral, Industrial Control PLC Module, Motor Control Interface Board, Medical Patient Monitoring Data Logger.
USB-to-CAN Industrial Bridge
The STM32F105VCT7's USB OTG full-speed peripheral combined with dual CAN 2.0B controllers (bxCAN) makes it ideal for USB-to-CAN gateway modules used in industrial automation, automotive diagnostics, and CANopen networks. The Cortex-M3 core handles USB CDC class enumeration and CAN frame transmission with deterministic latency, while the 64 KB SRAM buffers CAN traffic bursts. The 256 KB Flash is sufficient for USB stack (e.g., LibUSB) and CANopen/CANFestival protocols. Placed on a small PCB with USB Type-B connector and CAN transceiver (e.g., TJA1050), the part delivers a compact bridge solution operating at 72 MHz with 12 Mbps USB and 1 Mbit/s CAN simultaneously.

Human-Machine Interface (HMI) Panel Controller
The 100-pin LQFP package provides 80 GPIO pins, ample for driving TFT displays, keypads, status LEDs, and external peripherals in HMI panels. The STM32F105VCT7's two 12-bit ADCs support touch-screen digitizer scanning, while the SPI and SDIO peripherals connect to display controllers and microSD storage. Running at 72 MHz, the Cortex-M3 executes FreeRTOS-based UI frameworks smoothly with the 64 KB SRAM accommodating frame buffers. Designers typically pair the MCU with an external TFT controller over SPI and use the FSMC-less GPIO bit-banging for parallel LCD interfaces up to QVGA resolution.
Рекомендуется
USB Barcode Scanner / HID Peripheral
USB OTG full-speed with on-chip PHY enables direct USB device, host, or dual-role operation without external transceivers, ideal for barcode scanners, RFID readers, and HID peripherals. The STM32F105VCT7 runs USB HID class firmware at 72 MHz with minimal CPU overhead, leaving the 64 KB SRAM and 256 KB Flash available for application code, decode libraries, and buffer storage. The 12 Mbps USB FS bandwidth accommodates keyboard, mouse, barcode wedge, and custom HID reports with sub-1 ms latency. Designers can integrate a USB Type-C interface directly using PA11/PA12 pins with proper ESD protection.
Рекомендуется
Industrial Control PLC Module
With dual CAN, five USARTs, three SPI, and two I2C interfaces, the STM32F105VCT7 serves as the main processor for compact PLC modules and industrial control boards. The Cortex-M3 at 72 MHz executes IEC 61131-3 runtimes or ladder-logic interpreters, while the 80 GPIO pins drive relays, optocouplers, and isolated digital I/O. The wide 2.0-3.6 V supply tolerance accommodates industrial 24 V systems stepped down to 3.3 V via isolated DC-DC converters. The 105C operating temperature (Grade 7) supports factory-floor cabinets without additional cooling.
Рекомендуется
Motor Control Interface Board
The STM32F105VCT7's ten timers (including one advanced-control timer with complementary PWM outputs) provide ample PWM channels for brushless DC (BLDC) and stepper motor control interface boards. The 12-bit ADCs sample current and back-EMF signals at up to 1 MSPS, while the Cortex-M3 executes field-oriented control (FOC) algorithms at 72 MHz. Designers typically pair the MCU with external gate drivers (e.g., ST L6234) and use the CAN peripherals for multi-axis communication. The 64 KB SRAM limits FOC to single-axis or basic dual-axis implementations.
Рекомендуется
Medical Patient Monitoring Data Logger
Medical-grade patient monitoring peripherals (pulse oximeters, thermometers, glucose meters) leverage the STM32F105VCT7's USB OTG for data transfer to PCs, dual CAN for hospital network connectivity, and SDIO for local data storage on microSD cards. The 256 KB Flash stores firmware with embedded USB stack, while the 64 KB SRAM buffers continuous monitoring data. The Cortex-M3 deterministic interrupt response (12-cycle tail-chaining) ensures accurate sensor sampling timing. The -40C to +105C temperature range supports battery-powered portable medical devices.

Ключевые отличия
- USB OTG with dual CAN in connectivity line (против STM32F103VCT6)
- No on-chip Ethernet MAC for cost optimization (против STM32F107VCT7)
- Industrial temperature grade with Grade 7 rating (против STM32F105VCT6)
Заметки по проектированию
The STM32F105VCT7 has 7 VDD pins (pins 11, 27, 36, 49, 63, 75, 100) and corresponding VSS pins that must each be decoupled with a 100 nF ceramic capacitor placed within 5 mm of each pin. Add a bulk 10 uF tantalum or ceramic capacitor near the regulator output. VDDA requires a separate 10 nF + 1 uF filter; tying VDDA directly to VDD without filtering degrades ADC SNR by 5-10 dB. VBAT must be tied to VDD if RTC/battery backup is unused, never left floating.
Route the HSE crystal traces (OSC_IN/OSC_OUT) symmetrically with traces under 5 mm length and a ground guard ring to prevent crosstalk with switching nodes. For USB, route PA11/PA12 as a 90-ohm differential pair with matched length within 2 mm and a ground plane underneath. The SDIO bus to microSD cards must have series 33-ohm resistors for signal integrity at 48 MHz clock. Keep the BOOT0 pin accessible via a test pad or jumper for firmware recovery.
Do not assume the F105 has Ethernet like the F107 - the F105 has the MAC registers reserved but no Ethernet peripheral. The '7' suffix indicates Grade 7 (-40C to +105C), not 125C - for 125C automotive use, look at STM32F105VCT7B or AEC-Q100 qualified parts. When migrating from STM32F103 firmware, verify bxCAN register initialization - the F105/F107 bxCAN has enhanced filter banks that differ from F103. USB OTG requires the PA11/PA12 pins to be at 3.3 V; lower VDD voltages disable USB PHY.
