The 48-UFQFPN package with exposed pad (7x7 mm) keeps the PCB footprint small while the pad helps pull heat from the die in continuous operation.
44 I/O lines give enough headroom for a keypad, a small TFT display, and a few sensor interrupts. Two 12-bit DACs and a 17-channel 12-bit ADC handle analog I/O without an external converter.
ST lists the STM32G071CBU6 as an active product — no last-time-buy notice, no EOL risk in the near term.
The two share the same core, Flash density, RAM, and peripheral set. The difference is the package: the CBU6 comes in a 48-UFQFPN (7x7 mm) with exposed pad, while the CBT6 uses a 48-LQFP (7x7 mm) with gull-wing leads. The UFQFPN saves board height and has a smaller footprint, but the LQFP is easier to hand-solder and inspect. Choose the UFQFPN for compact, reflow-only assembly; pick the LQFP for prototyping or rework-friendly layouts.
