72 MHz Cortex-M4 with rich analog — built for digital power and motor control
The STMicroelectronics STM32F334C8T6 is a 32-bit ARM Cortex-M4 microcontroller from the STM32F3 series, clocked at 72 MHz and packing 64 KB of Flash program memory alongside 12 KB of SRAM. 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.
