The STM32F303CCT7 is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics' STM32F3 series, running at 72 MHz with a single-precision FPU and DSP instructions.
Rated for -40°C to 105°C ambient, this MCU operates from a 2 V to 3.6 V supply range.
The 15-channel 12-bit ADC and dual 12-bit DAC handle analog front-end tasks without an external converter.
Within the STM32F303 series, pin-compatible alternatives include the STM32F303CBT6 (128 KB Flash) and STM32F303RCT7 (256 KB Flash, 64-pin). For a production-ready replacement with similar peripherals, ST recommends evaluating the STM32G431 series, though pin compatibility should be verified against the target package.
