Product details

48 MHz Cortex-M0 with integrated analog — BOM-fit for sensor and control applications

The 32 KB Flash (32K x 8) and 8 KB SRAM (8K x 8) define the application envelope. For a typical sensor node running a 10–15 KB firmware image with a 2 KB data buffer, this leaves comfortable headroom. If the design needs over-the-air update staging or a larger protocol stack, the pin-compatible STM32F051K8T6TR (64 KB Flash, 8 KB RAM) is the natural step-up within the same 32-LQFP footprint.

Analog integration — 13-channel 12-bit ADC and 12-bit DAC

The 13-channel 12-bit ADC covers multiple analog inputs (current/voltage sensors, potentiometers, thermistors) without an external multiplexer. The single 12-bit DAC can generate a reference voltage or drive an analog output for a setpoint or trim signal.

Temperature grade and environment — industrial range, not automotive

The 32-LQFP (7x7 mm) package is hand-solderable and rework-friendly, which helps during prototyping and low-volume production.

Frequently asked questions

Is the STM32F051K6T6TR obsolete or EOL?

No. The lifecycle status is Active.

What is the difference between STM32F051K6T6TR and STM32F051K8T6TR?

The STM32F051K8T6TR doubles the Flash to 64 KB while keeping the same 32-LQFP footprint, 48 MHz core, 8 KB RAM, and peripheral set. The K6 variant (32 KB Flash) is the cost-optimized choice for firmware images under 30 KB.

Is the STM32F051K6T6TR compatible with 3.3 V logic?

Yes. All I/O pins are 5 V tolerant when configured correctly per the STM32F0 reference manual.

What are the programming options for this MCU?

It supports SWD (Serial Wire Debug) for programming and debugging via a standard ST-Link or J-Link probe.
