Product details

Industrial temperature grade — what it buys you

The 105°C ceiling is the practical limit for convection-cooled industrial PCBs; above that you would need a higher-temperature-grade device or active cooling.

Package and layout — 32-LQFP (7x7 mm)

Housed in a 32-pin LQFP with a 7x7 mm body, this is a hand-solderable, inspectable package that fits two-layer boards without micro-vias. The 25 I/O lines are enough for a modest sensor array or a small keypad-and-display interface. Surface-mount only — no through-hole option.

Frequently asked questions

Does STM32F051K6T7 have an internal oscillator?

Yes, the oscillator type is listed as Internal, so no external crystal or ceramic resonator is required for the core clock. An external clock source can still be used if tighter timing accuracy is needed.

What is the difference between STM32F051K6 and STM32F051K8?

The STM32F051K8 doubles the program memory to 64 KB Flash while keeping the same 48 MHz Cortex-M0 core, 8 KB RAM, 32-LQFP package, and peripheral set. The K6 variant is the 32 KB Flash version.
