This line is specifically designed for applications that require USB and CAN connectivity. The device integrates 128KB of Flash program memory and 64KB of SRAM. The USB 2.0 full-speed OTG interface includes an integrated PHY and supports host, device, and OTG modes. Two CAN 2.0B controllers provide connectivity for automotive and industrial networks. A comprehensive set of communication peripherals includes 5 USARTs, 3 SPI ports, and 2 I2C interfaces. The dual 12-bit ADC subsystem can sample at up to 1Msps.","working_principle":"The STM32F105VBT6 operates around the ARM Cortex-M3 core with its NVIC supporting up to 43 maskable interrupt channels. The multi-layer AHB bus matrix provides simultaneous access to Flash, SRAM, and peripherals from the core and DMA. The USB OTG controller integrates a full-speed PHY and supports SRP and HNP for OTG operation. The dual CAN controllers implement the CAN 2.0B protocol with hardware message filtering and transmit FIFOs. The ADC subsystem uses a 12-bit successive approximation architecture with configurable scan, continuous, and discontinuous modes. Power management includes multiple low-power modes (sleep, stop, standby) with wakeup sources from interrupts, CAN, USB, and external pins.","pin_description":"
