STM32L4Q5CGT6 from STMicroelectronics, in a LQFP-48(7x7). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model, then checked against ST open pin data); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VBAT power_in Backup-domain supply for the RTC, 32 kHz oscillator and backup registers, specified from 1.55 V to 3.6 V and used when VDD is not present.
2 PC13 bidirectional GPIO supplied through the power switch that sinks only 3 mA, so output use is limited to 2 MHz with a 30 pF load and it must not be used as a current source; it also carries RTC_TAMP1/RTC_TS/RTC_OUT and WKUP2.
3 PC14-OSC32_IN bidirectional GPIO supplied through the power switch with the same 3 mA and 2 MHz / 30 pF output limits, and it is the 32 kHz LSE oscillator input OSC32_IN.
4 PC15-OSC32_OUT bidirectional GPIO supplied through the power switch with the same 3 mA and 2 MHz / 30 pF output limits, and it is the 32 kHz LSE oscillator output OSC32_OUT.
5 PH0-OSC_IN bidirectional 5 V-tolerant (FT) GPIO that doubles as the high-speed external oscillator input OSC_IN.
