STMicroelectronics STM32G031C8U6TR

The STM32G031C8U6TR is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at 64MHz. It features 64KB flash and 8KB SRAM in a 48-UFQFN package with exposed pad for improved thermal performance. Designed for general-purpose embedded applications, it offers a balanced mix of performance, I/O, and low power.

• More I/O Options: 48-pin package provides greater flexibility for complex interfaces and multi-sensor systems.
• Enhanced Thermal Management: Exposed pad improves heat dissipation for reliable operation in enclosed spaces.
• Cost-Effective: Optimized feature set reduces BOM cost while maintaining essential peripherals.
• Robust Reset Management: Brown-out and power-on reset circuits prevent erratic behavior during power fluctuations.
