The 48-UFQFPN package with exposed pad (7x7 mm) is the key mechanical difference from the LQFP-48 variant — it saves board area and improves thermal transfer through the pad, but requires a QFN-style solder-paste stencil and X-ray inspection for voiding under the centre pad.
The STM32F072C8U6TR includes CANbus, USB, multiple SPI and I²C channels, plus UART/USART with LIN and IrDA support.
The UFQFPN package here is pin-compatible in function but has a different footprint — the centre pad on the UFQFPN is a thermal/ground pad, whereas the LQFP has no exposed pad. Board redesign is required for the package change; the firmware is identical.
The core is rated for 48 MHz maximum, driven by an internal oscillator or an external clock source. The Cortex-M0 pipeline runs single-cycle multiply and branch at this speed.
