The STM32F070C6T6: The 48 MHz ARM Cortex-M0 core runs the 12-bit ADC with 12 channels for analog inputs.
The 32 KB Flash (32K x 8) and 6 KB SRAM handle the program store and data buffers.
The 48-LQFP (7x7 mm) gives 37 usable I/O lines.
ROHS3 compliant.
That is the entry-level density in the STM32F070 line — enough for USB HID/CDC, sensor fusion, or motor control with moderate data logging.
The STM32L151CBU6A is a Cortex-M3 part at 32 MHz with lower power but no USB, in a different package (UFBGA). It is not a pin-compatible drop-in. For a USB-capable second source within the STM32F0 family, look at the STM32F072 series (48 MHz, 128 KB Flash, USB) — same 48-LQFP footprint, but check the peripheral set differences.
