Product details

48 MHz Cortex-M0 with 64 KB Flash — what it fits

The 55 I/O lines and rich analog front end — 19-channel 12-bit ADC plus a single 12-bit DAC — make it a natural fit for industrial sensor nodes, motor-control feedback loops, and human-machine interfaces where you need to digitise multiple analog signals without external muxes.

Supply range, temperature grade, and package

The STM32F051R8H6 operates from 2.0 V to 3.6 V, covering single-cell Li-Po and 3.3 V regulated rails.

On-chip peripherals include DMA, I²S, POR, PWM, and WDT.

Frequently asked questions

What is the difference between STM32F051R8H6 and STM32F051R8T6?

The two parts share the same core, memory, and peripheral set. The difference is the package: STM32F051R8H6 comes in a 64-UFBGA (5x5 mm) while STM32F051R8T6 is in a 64-LQFP. The BGA variant saves board area but requires a reflow profile for the 0.5 mm ball pitch; the LQFP is easier to hand-solder and inspect. They are not pin-compatible — the BGA and LQFP pinouts differ.
