With 128KB Flash and 40KB SRAM (including 8KB CCM RAM), it features the most comprehensive analog peripheral set in the STM32F3 series: four 12-bit ADCs with 5 MSps combined sampling, two 12-bit DACs, seven fast comparators, and four internal operational amplifiers with programmable gain amplifier (PGA) mode. This analog integration eliminates external signal conditioning components in motor control, power conversion, and instrumentation applications. The 100-pin LQFP package provides 87 I\/Os including dual CAN, USB, and multiple communication interfaces.","working_principle":"The STM32F303VBT6 uses an ARM Cortex-M4 core with single-precision FPU executing DSP instructions (MAC, SIMD) in hardware. The four ADCs can operate in simultaneous or interleaved modes for higher effective sampling rates or synchronized multi-channel measurement. Each of the seven comparators has configurable hysteresis, blanking, and output routing to timers for fault protection. The four internal op amps can be configured as PGAs with programmable gain (2x-16x) for direct sensor signal amplification without external components. The advanced-control timers (TIM1\/TIM8) generate up to 6 complementary PWM channels with dead-time insertion, break inputs from comparators, and center-aligned mode for motor control. The 8KB CCM (Core Coupled Memory) RAM provides zero-wait-state execution for time-critical code.","pin_description":"
