Product details

48 MHz Cortex-M0 with 64 KB Flash — fit for industrial control and sensor fusion

Industrial temperature grade and BGA package — design-in considerations

The 64-UFBGA (5x5 mm) footprint is the tightest package option in the STM32F051 family — the 0.5 mm ball pitch requires controlled impedance and via-in-pad techniques if you route all 55 I/O. On-chip DMA, POR, PWM, and WDT reduce external glue logic.

STMicroelectronics lists the STM32F051R8H7TR as Active. For dual-sourcing flexibility, the STM32F051 family includes several Flash and package variants — the base product number STM32F051 covers the common footprint options.

This STM32F051R8H7TR is available to source through independent distribution channels. No franchised-stock claim is made; each lot is traceable to ensure authenticity.

Frequently asked questions

What is the difference between STM32F051R8H7TR and STM32F051R8T6?

The primary difference is the package: the STM32F051R8H7TR comes in a 64-UFBGA (5x5 mm) package, while the STM32F051R8T6 uses an LQFP-48 or LQFP-64 package. The BGA variant saves board area but requires more complex PCB routing and assembly.

Is STM32F051R8H7TR RoHS compliant?

The STM32F051R8H7TR is listed as RoHS compliant per STMicroelectronics' standard for the STM32F0 series. No separate certificate is provided here; the datasheet includes the compliance declaration.
