Product details

The STM32F091VCH7 is an STMicroelectronics STM32F0-series 32-bit MCU built around the ARM Cortex-M0 core, running at 48 MHz.

Peripheral set and connectivity – CAN, I²S, and 12-bit ADC/DAC

That CAN controller is the differentiator versus the smaller STM32F0 parts – if the design needs a gateway node on a vehicle or industrial bus, this variant saves an external CAN transceiver interface chip.

100-UFBGA – rework and footprint realities

No hand-soldering; this is a machine-place part.

Lifecycle status and sourcing

The base product number is STM32F091, and the part is currently in volume production.

Frequently asked questions

What is the core processor of STM32F091VCH7?

ARM Cortex-M0, 32-bit single-core, running at 48 MHz.

When sourcing STM32F091VCH7, what's the closest functional second-source – STM32L151CBU6A?

The STM32L151CBU6A is not a pin-compatible or direct second-source for the STM32F091VCH7. It uses a Cortex-M3 core at 32 MHz, has 37 I/O, and a 1.8 V supply – different voltage domain, different footprint, and fewer pins. For a dual-sourcing strategy, stick with STM32F0-series parts sharing the same 100-UFBGA footprint and peripheral set.
