It is designed for real-time control applications that demand a mix of compute throughput and analog integration — think digital power supplies, motor drives, and field-oriented control loops where the 15-channel 12-bit ADC and three 12-bit DACs handle simultaneous current/voltage sensing and waveform generation without external converters. Operates from 2 V to 3.6 V and is rated for -40 °C to 85 °C. At 72 MHz the Cortex-M4 executes a single-cycle MAC or hardware divide.","metaTitle":"STM32F334C8T6 STM32F3 ARM Cortex-M4 MCU, 72 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F334C8T6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 64 KB Flash, 12 KB RAM, 15x12-bit ADC, 3x12-bit DAC, CANbus, in 48-LQFP.
