USB connectivity is available on-chip — the part includes a USB peripheral, so a USB device interface (e.g., virtual COM port, HID) can be added without an external PHY. The 25 available I/O pins in the 32-UFQFPN package are enough for a sensor hub or a simple human-machine interface with a small display and a few buttons. The ROHS3 compliance is confirmed on the manufacturer's documentation. ## Design-in checklist: package, supply, and temperature The internal oscillator is available, but for USB operation an external crystal (typically 8 MHz or 12 MHz) is recommended for accurate bit-rate generation.","metaTitle":"STM32L072KBU3 MCU, ARM Cortex-M0+, 32 MHz, 128 KB Flash","metaDescription":"STM32L072KBU3 32-bit MCU with 32 MHz ARM Cortex-M0+, 128 KB Flash, 20 KB RAM, 6 KB EEPROM, USB, 1.65-3.6 V supply, -40 to 125°C.
