Features dual CAN 2.0B with dedicated SRAM, USB 2.0 FS OTG with on-chip PHY, 5 USART, 3 SPI with I2S, 2 I2C, 2\u00d7 12-bit ADC, 2\u00d7 12-bit DAC, and 12-channel DMA. R suffix denotes 64-pin, B suffix denotes 128KB Flash, T suffix denotes LQFP package, 6 suffix denotes -40 to 85\u00b0C industrial temp. The connectivity line is designed for applications requiring multiple communication interfaces (CAN, USB, Ethernet-ready).","working_principle":"The STM32F105 uses the ARM Cortex-M3 core with a 3-stage pipeline executing Thumb-2 instructions. The Nested Vectored Interrupt Controller (NVIC) provides low-latency interrupt handling with up to 60 maskable interrupt channels. The AHB\/APB bus matrix connects the CPU to Flash (with prefetch buffer for zero-wait-state at 72MHz), SRAM, and peripherals. The connectivity line adds dedicated SRAM for CAN (512B) and USB (1.25KB), reducing DMA contention with main SRAM. The dual CAN controllers support CAN 2.0B active with time-triggered communication option. The USB OTG controller supports Host, Device, and OTG modes with HNP\/SRP protocol handling. The 12-channel DMA can offload data transfers for USART, SPI, I2C, ADC, DAC, and memory-to-memory operations.","pin_description":"
