Product details

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.

Frequently asked questions

Is STM32F334C8T6 obsolete or active?

The STM32F334C8T6 is active in production — no end-of-life notice has been issued by STMicroelectronics.

What is the maximum frequency of STM32F334C8T6?

The core runs at 72 MHz.

Is STM32F334C8T6 compatible with 3.3V logic?

Yes — the supply range is 2 V to 3.6 V, so 3.3 V logic is within the operating window without external level translation.

What are the equivalents of STM32F334C8T6?

Within the STM32F334 family, pin-compatible density variants exist (e.g., STM32F334C4T6 with 16 KB Flash, STM32F334C6T6 with 32 KB Flash) that share the same 48-LQFP footprint and peripheral map, allowing a firmware- or cost-driven swap without a PCB respin.
