Product details

64 MHz Cortex-M0+ with 64 KB Flash — entry-level control MCU

48-UFQFPN 7x7 — compact footprint for space-constrained boards

Housed in a 48-lead UFQFPN with an exposed pad (7x7 mm), this package suits two-layer PCBs where thermal relief and routing density matter. The exposed pad needs a solid ground-plane solder connection for both thermal and electrical performance. Surface-mount only; no through-hole variant exists.

Frequently asked questions

What is the operating voltage of STM32G031C8U6?

The supply range is 1.7 V to 3.6 V on Vcc/Vdd. The internal oscillator and brown-out detect operate within this window, so no external regulator is required if the rail stays in that band.

Is STM32G031C8U6 5V tolerant?

No, the STM32G031C8U6 is not 5V tolerant. The maximum supply is 3.6 V, and I/O pins are not rated for 5 V levels. Level shifters are needed for 5 V logic interfaces.

What are the key specifications of STM32G031C8U6?

64 MHz ARM Cortex-M0+ core, 64 KB Flash, 8 KB RAM, 44 I/O, 19-channel 12-bit ADC, serial interfaces including I²C, SPI, UART/USART, IrDA, LINbus, and I²S, in a 48-UFQFPN 7x7 mm package, operating from -40 to 85°C.
