Product details

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

Peripherals and connectivity — what is on the die

There is no built-in USB interface. The data converter block provides 19 analog inputs multiplexed into a 12-bit ADC.

Memory sizing — 64 KB Flash, 8 KB RAM

The 64 KB Flash (64K x 8) and 8 KB SRAM (8K x 8) place this part in the value tier of the STM32G0 family. It fits firmware images for sensor fusion, basic motor control loops, and UART/SPI protocol handling.

Lifecycle — active, no end-of-life watch needed

Package and mounting — 48-LQFP, hand-solder friendly

The 7x7 mm body fits tight PCB layouts. No exposed thermal pad — junction-to-ambient thermal performance depends on copper area on the inner layers.

Frequently asked questions

Does STM32G031C8T7 have a built-in USB interface?

No. The connectivity block includes I²C, IrDA, LINbus, SPI, and UART/USART, but there is no USB peripheral on this die. If USB is required, look at the STM32G0B1 or STM32G4 series which embed a USB device or OTG controller.

What is the difference between STM32G031C8T7 and STM32G031C6T7?

The two parts differ in Flash and RAM density. The STM32G031C8T7 carries 64 KB Flash and 8 KB SRAM, while the STM32G031C6T7 carries 32 KB Flash and 6 KB SRAM. Both use the same 48-LQFP package, same 64 MHz Cortex-M0+ core, same peripheral set, and same -40 to 105 °C temperature range. The C8 variant is the higher-density option for firmware that needs more code space or buffer RAM.
