Product details

Peripherals and I/O — what the 50 GPIOs connect to

The STM32F078RBH7TR: Fifty GPIOs bring out SPI, I²C, USART/UART, USB, IrDA, I²S, LINbus, HDMI-CEC, PWM timers, DMA, and an internal oscillator.

64-UFBGA — not a field-swap package

The 64-UFBGA (5x5 mm) is a 0.5 mm pitch BGA. It needs a controlled-depth stencil, X-ray inspection, and a reflow oven — not something you swap on site with a soldering iron. If your application requires field replacement, look at the LQFP-48 or LQFP-64 variants in the same STM32F0 family. For a production board that stays assembled, the BGA saves 30% board area versus a TQFP.

Frequently asked questions

What is the closest pin-compatible alternative to STM32F078RBH7TR in this component family?

The STM32F072RB is a close sibling in the same STM32F0 family with the same 48 MHz Cortex-M0 core and 128 KB Flash, but in an LQFP-64 package instead of the 64-UFBGA. The BGA footprint is not pin-compatible with the LQFP — you would need a board respin to swap between them. Within the 64-UFBGA package option, the STM32F078RBH7TR is the highest-density variant; lower Flash/RAM options like the STM32F058 use the same BGA land pattern but with reduced memory.
